They can also be divided into those that are fractured and those that produce from primary pore spaces or vugs. The first successful oil well in the Ouachita Mountains was drilled in 1913 or 1914.

Chemistry of mineral phases in conjunction with textural features suggests that the xenoliths formed in different parts of a convecting magma chamber that underwent a period of closed system fractionation.

This coal bed contains only fine elastic partings and is overlain by regionally extensive, closely spaced channel-belt deposits in the Upper Potomac coal field of the Appalachian basin. A blind-thrust ridge may have formed a sediment trap and prevented c coarse fluvial sediments from entering the swamp during a period (Westphalian D) when the thick Upper Freeport peat accumulated. Anticlinal thrust ridges and associated depressions may have existed uninterrupted for about 40 km parallel to the Appalachian orogen. Sediment shed from the breached anticlinal ridges accumulated in the sediment trap and was carried out of the ends of the trap by streams that occupied the shear zone at the ends of the blind-thrust ridge. The extent, parallel to the orogen, of thick, areally extensive UF is related to the length of the blind-thrust ridge that, in turn, controlled the spacing of the river-derived coarse clastic sediments that entered the main basin from the east. The thrust plane eventually emerged to the surface of the blind-thrust ridge and peat accumulation was terminated when the ridge became eroded and the sediment trapped behind it was released. The peat was buried by abundant coarse clastic sediment, which formed closely spaced channel belts and intervening flood basins. This model has implications for widespread peat deposits (now coal) that developed in tropical regions a few hundred kilometers from the sea in a tectonically active foreland basin.</p></div></div></div></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0166-5162(89)90055-4","issn":"01665162","usgsCitation":"Belt, E.S., and Lyons, P., 1990, Thrust-ridge paleodepositional model for the Upper Freeport coal bed and associated clastic facies, Upper Potomac coal field, Appalachian Basin, U.S.A.: International Journal of Coal Geology, v. 16, no. 1-3, p. 167-170, https://doi.org/10.1016/0166-5162(89)90055-4.","productDescription":"4 p.","startPage":"167","endPage":"170","numberOfPages":"4","costCenters":[],"links":[{"id":223468,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"16","issue":"1-3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb357e4b08c986b325d30","contributors":{"authors":[{"text":"Belt, Edward S.","contributorId":96422,"corporation":false,"usgs":false,"family":"Belt","given":"Edward","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":373462,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lyons, P.C.","contributorId":87285,"corporation":false,"usgs":true,"family":"Lyons","given":"P.C.","email":"","affiliations":[],"preferred":false,"id":373461,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Relative to the mid-crustal heat source model, the lateral-flow model suggests a more limited geothermal resource base, but a better-defined exploration target. We simulated ground-water flow and heat transport through two cross sections trending west from the Cascade range crest in order to explore the implications of the two models. The thermal input for the alternate conceptual models was simulated by varying the width and intensity of a basal heat-flow anomaly and, in some cases, by introducing shallower heat sources beneath the Quaternary arc. Near-surface observations in the Breitenbush Hot Springs area are most readily explained in terms of lateral heat transport by regional ground-water flow; however, the deep thermal structure still cannot be uniquely inferred. The sparser thermal data set from the McKenzie River area can be explained either in terms of deep regional ground-water flow or in terms of a conduction-dominated system, with ground-water flow essentially confined to Quaternary rocks and fault zones.","largerWorkTitle":"Transactions - Geothermal Resources Council","conferenceTitle":"1990 International Symposium on Geothermal Energy","conferenceDate":"20 August 1990 through 24 August 1990","conferenceLocation":"Kailua-Kona, HI, USA","language":"English","publisher":"Publ by Geothermal Resources Council","publisherLocation":"Davis, CA, United States","issn":"01935933","isbn":"0934412677","usgsCitation":"Ingebritsen, S.E., and Paulson, K., 1990, Numerical simulation of hydrothermal circulation in the Cascade Range, north-central Oregon, <i>in</i> Transactions - Geothermal Resources Council, v. 14, no. pt 1, Kailua-Kona, HI, USA, 20 August 1990 through 24 August 1990, p. 691-698.","startPage":"691","endPage":"698","numberOfPages":"8","costCenters":[],"links":[{"id":222770,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"14","issue":"pt 1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6925e4b0c8380cd73ba9","contributors":{"authors":[{"text":"Ingebritsen, S.

The top of the reef is now 150-160 m below sea level. Radiocarbon and Useries dating indicates that it drowned about 13.9 ka by the combined effects of island subsidence (2.5 mm/year) and the rapid rise of sea level at the end of the last glaciation so that the relative submergence rate of more than 10 mm/year exceeded the upward growth rate of the reef. The submerged reef caps the offshore part of the southwest rift-zone ridge of Mauna Loa, which has apparently undergone little volcanic activity offshore since 170 ka, and possibly since 270 ka. This fact suggests that rift zone activity is becoming increasingly restricted toward the upper part of the volcano, a condition possibly heralding the end of the shield-building stage. ?? 1990 Springer-Verlag.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Volcanology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Springer-Verlag","doi":"10.1007/BF00302049","issn":"02588900","usgsCitation":"Moore, J., Normark, W.R., and Szabo, B.J., 1990, Reef growth and volcanism on the submarine southwest rift zone of Mauna Loa, Hawaii: Bulletin of Volcanology, v. 52, no. 5, p. 375-380, https://doi.org/10.1007/BF00302049.","startPage":"375","endPage":"380","numberOfPages":"6","costCenters":[],"links":[{"id":205348,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00302049"},{"id":223203,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"52","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a419e4b0e8fec6cdba42","contributors":{"authors":[{"text":"Moore, J.G.","contributorId":67496,"corporation":false,"usgs":true,"family":"Moore","given":"J.G.","email":"","affiliations":[],"preferred":false,"id":372841,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Normark, W.

Formation of these rocks within or near an island arc is indicated by the absence of pelagic sediments and the abundance of pillow basalt, turbiditic sediments, lahar deposits, and basaltic to rhyolitic tuff. The oldest extrusive rocks, which range from tholeiites with MORB characteristics to calc-alkaline andesites and rhyolites, formed in a young, relatively un-evolved island are or in a back-arc basin sufficiently close to an arc to receive calc-alkaline lava flows and coarse-grained, arc-derived detritus. tus. Overlying turbidites and lahar deposits of the Kaffan sandstone point to the initiation of a rifting event. High-Ti basalts, which erupted above the Kaffan sandstone, and related diabase are interpreted to be magmatic products of incipient intra-arc rifting. Renewed arc volcanism produced calc-alkaline volcanic rocks that interfingered with the high-Ti basalt and later dominated the section as the volcanic apron of the arc prograded basinward. Extrusion of voluminous calc-alkaline tuff may have been contemporaneous with intrusion of granodiorite and gravity-driven landsliding.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1990)102<1007:GAOOTL>2.3.CO;2","usgsCitation":"Quick, J.E., 1990, Geology and origin of the late Proterozoic Darb Zubaydah ophiolite, Kingdom of Saudi Arabia: Geological Society of America Bulletin, v. 102, no. 8, p. 1007-1020, https://doi.org/10.1130/0016-7606(1990)102<1007:GAOOTL>2.3.CO;2.","productDescription":"14 p.","startPage":"1007","endPage":"1020","numberOfPages":"14","costCenters":[],"links":[{"id":223469,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Saudi Arabia","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[42.77933,16.34789],[42.64957,16.77464],[42.34799,17.07581],[42.27089,17.47472],[41.75438,17.83305],[41.22139,18.6716],[40.93934,19.48649],[40.24765,20.17463],[39.80168,20.33886],[39.1394,21.2919],[39.0237,21.98688],[39.06633,22.57966],[38.49277,23.68845],[38.02386,24.07869],[37.48363,24.28549],[37.15482,24.85848],[37.20949,25.08454],[36.93163,25.60296],[36.6396,25.82623],[36.24914,26.57014],[35.64018,27.37652],[35.13019,28.06335],[34.63234,28.05855],[34.78778,28.60743],[34.83222,28.95748],[34.95604,29.35655],[36.06894,29.19749],[36.50121,29.50525],[36.74053,29.86528],[37.50358,30.00378],[37.66812,30.33867],[37.99885,30.5085],[37.00217,31.50841],[39.00489,32.01022],[39.19547,32.16101],[40.39999,31.88999],[41.88998,31.19001],[44.7095,29.17889],[46.56871,29.09903],[47.45982,29.00252],[47.70885,28.52606],[48.41609,28.552],[48.80759,27.68963],[49.29955,27.46122],[49.47091,27.11],[50.15242,26.68966],[50.21294,26.27703],[50.1133,25.94397],[50.23986,25.60805],[50.52739,25.32781],[50.66056,24.9999],[50.81011,24.75474],[51.11242,24.55633],[51.38961,24.62739],[51.57952,24.2455],[51.61771,24.01422],[52.00073,23.00115],[55.0068,22.49695],[55.20834,22.70833],[55.66666,22],[54.99998,19.99999],[52.00001,19],[49.11667,18.61667],[48.18334,18.16667],[47.46669,17.11668],[47,16.95],[46.74999,17.28334],[46.36666,17.23332],[45.4,17.33334],[45.21665,17.43333],[44.06261,17.41036],[43.79152,17.31998],[43.38079,17.57999],[43.1158,17.08844],[43.21838,16.66689],[42.77933,16.34789]]]},\"properties\":{\"name\":\"Saudi Arabia\"}}]}","volume":"102","issue":"8","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2413e4b0c8380cd57d93","contributors":{"authors":[{"text":"Quick, J.

Geologists call Mount St. Helens a composite volcano (or stratovolcano), a term for steepsided, often symmetrical cones constructed of alternating layers of lava flows, ash, and other volcanic debris. Composite volcanoes tend to erupt explosively and pose considerable danger to nearby life and property. In contrast, the gently sloping shield volcanoes, such as those in Hawaii, typically erupt nonexplosively, producing fluid lavas that can flow great distances from the active vents. Although Hawaiian-type eruptions may destroy property, they rarely cause death or injury. Before 1980, snow-capped, gracefully symmetrical Mount St. Helens was known as the \"Fujiyama of America.\" Mount St. Helens, other active Cascade volcanoes, and those of Alaska form the North American segment of the circum-Pacific \"Ring of Fire,\" a notorious zone that produces frequent, often destructive, earthquake and volcanic activity.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/7000008","usgsCitation":"Tilling, R.I., Topinka, L.J., and Swanson, D., 1990, Eruptions of Mount St. Helens : Past, present, and future (Revised Edition - 1990; Version 1.01 March 19, 2002): General Interest Publication, HTML Document, https://doi.org/10.3133/7000008.","productDescription":"HTML Document","additionalOnlineFiles":"Y","costCenters":[],"links":[{"id":134286,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":265542,"type":{"id":12,"text":"Errata"},"url":"https://pubs.usgs.gov/gip/msh/revision.html"},{"id":265565,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/gip/msh/title.html"},{"id":265566,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/gip/msh/contents.html"}],"country":"United States","state":"Washington","county":"Skamania","otherGeospatial":"Mount St. Helens","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.2501,45.5477 ], [ -122.2501,46.3892 ], [ -121.5148,46.3892 ], [ -121.5148,45.5477 ], [ -122.2501,45.5477 ] ] ] } } ] }","edition":"Revised Edition - 1990; Version 1.01 March 19, 2002","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fde92","contributors":{"authors":[{"text":"Tilling, Robert I. 0000-0003-4263-7221 rtilling@usgs.gov","orcid":"https://orcid.org/0000-0003-4263-7221","contributorId":2567,"corporation":false,"usgs":true,"family":"Tilling","given":"Robert","email":"rtilling@usgs.gov","middleInitial":"I.","affiliations":[],"preferred":true,"id":343956,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Topinka, Lyn J.","contributorId":102850,"corporation":false,"usgs":true,"family":"Topinka","given":"Lyn","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":343958,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Swanson, Donald A. 0000-0002-1680-3591","orcid":"https://orcid.org/0000-0002-1680-3591","contributorId":22303,"corporation":false,"usgs":true,"family":"Swanson","given":"Donald A.","affiliations":[],"preferred":false,"id":343957,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Waters were sampled within three different vegetative life zones and two transition zones. Water temperatures ranged from 24-25 ??C in streams draining lower elevations (35-250 m) in tropical wet forest, to 10 ??C in a crater lake at 2600 m in montane forest. Ambient phosphorus levels (60-300 ??g SRP L-1; 66-405 ??g TP L-1) were high at sites within six pristine drainages at elevations between 35-350 m, while other undisturbed streams within and above this range in elevation were low (typically <30.0 ??g SRP L-1). High ambient phosphorus levels within a given stream were not diagnostic of riparian swamp forest. Phosphorus levels (but not nitrate) were highly correlated with conductivity, Cl, Na, Ca, Mg and SO4. Results indicate two major stream types: 1) phosphorus-poor streams characterized by low levels of dissolved solids reflecting local weathering processes; and 2) phosphorus-rich streams characterized by relatively high Cl, SO4, Na, Mg, Ca and other dissolved solids, reflecting dissolution of basaltic rock at distant sources and/or input of volcanic brines. Phosphorus-poor streams were located within the entire elevation range, while phosphorus-rich streams were predominately located at the terminus of Pleistocene lava flows at low elevations. Results indicate that deep groundwater inputs, rich in phosphorus and other dissolved solids, surface from basaltic aquifers at breaks in landform along faults and/or where the foothills of the central mountain range merge with the coastal plain. ?? 1990 Kluwer Academic Publishers.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers","doi":"10.1007/BF00018971","issn":"00188158","usgsCitation":"Pringle, C.M., Triska, F., and Browder, G., 1990, Spatial variation in basic chemistry of streams draining a volcanic landscape on Costa Rica's Caribbean slope: Hydrobiologia, v. 206, no. 1, p. 73-85, https://doi.org/10.1007/BF00018971.","startPage":"73","endPage":"85","numberOfPages":"13","costCenters":[],"links":[{"id":205345,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF00018971"},{"id":223187,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"206","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b94b9e4b08c986b31ac0d","contributors":{"authors":[{"text":"Pringle, C.

The Peach Springs Tuff is the only known unit that can be correlated between isolated outcrops of Miocene strata from the central Mojave Desert of southeastern California to the western Colorado Plateau in Arizona, across five structural provinces, a distance of 350 km. Thus the age of the Peach Springs Tuff is important to structural and paleogeographic reconstructions of a large region. Biotite and sanidine separates from bulk samples of the Peach Springs Tuff from zones of welding and vapor-phase alteration have not produced consistent ages by the K-Ar method. Published ages of mineral separates from 17 localities ranged from 16.2 to 20.5 Ma. Discordant&nbsp;</span><sup>40</sup><span>Ar/</span><sup>39</sup><span>Ar incremental release spectra were obtained for one biotite and two of the sanidine separates. Ages that correspond to the last gas increments are as old as 27 Ma.

Laser fusion measurements yield a mean age of 18.51±0.10. The results suggest that sanidine and biotite K-Ar ages older than about 18.5 Ma are due to inherited Ar from pre-Tertiary contaminants, which likely were incorporated into the tuff during deposition. Sanidine K-Ar ages younger than 18 Ma probably indicate incomplete extraction of radiogenic&nbsp;</span><sup>40</sup><span>Ar, whereas laser fusion dates of biotite and hornblende younger than 18 Ma likely are due to postdepositional alteration. Laser fusion ages as high as 19.01 Ma on biotite grains from pumice suggest that minerals from pre-Tertiary country rocks also were incorporated in the magma chamber.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB095iB01p00571","issn":"01480227","usgsCitation":"Nielson, J.E., Lux, D.R., Dalrymple, G.B., and Glazner, A.F., 1990, Age of the Peach Springs Tuff, southeastern California and western Arizona: Journal of Geophysical Research Solid Earth, v. 95, no.

The oldest sedimentary rocks sampled were not fossiliferous, but are probably of Late Jurassic age. Sandstones and siltstones are the dominant lithologies except in the intervals between 1213 to 1450 m and 1993 to 2259 m where carbonates make up a major part of the section. Calcite is the primary cement throughout the section; chert, siderite, diagenetic clay and dolomite are locally important. The well contains coaly, gas-prone potential source rocks of Neocomian age, but these strata are only marginally mature for oil. The paleoenvironments recorded in the strata represent a general upward progression from nonmarine to marginal marine to neritic depositional conditions. These paleoenvironments are more marine than the stratigraphically equivalent sedimentary regimes of the New Jersey coastal plain to the west, but are generally more terrestrial than the paleoenvironments recorded in wells drilled seaward to the east. ?? 1990.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/0025-3227(90)90025-F","issn":"00253227","usgsCitation":"Poppe, L., Hall, R., Cousminer, H., Stanton, R., and Steinkraus, W., 1990, Biostratigraphy, lithofacies and paleoenvironments of the Gulf 718-1 well, U.S. Mid-Atlantic Outer Continental Shelf: Marine Geology, v. 92, no. 1-2, p. 27-50, https://doi.org/10.1016/0025-3227(90)90025-F.","productDescription":"24 p.","startPage":"27","endPage":"50","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":222948,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"U.S. Mid-Atlantic Outer Continental Shelf","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -76.00341796875,\n              36.89719446989036\n            ],\n            [\n              -72.02636718749999,\n              36.89719446989036\n            ],\n            [\n              -72.02636718749999,\n              41.0130657870063\n            ],\n            [\n              -76.00341796875,\n              41.0130657870063\n            ],\n            [\n              -76.00341796875,\n              36.89719446989036\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"92","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f19ee4b0c8380cd4ad3a","contributors":{"authors":[{"text":"Poppe, L.J.","contributorId":72782,"corporation":false,"usgs":true,"family":"Poppe","given":"L.J.","affiliations":[],"preferred":false,"id":372939,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hall, R.E.","contributorId":7007,"corporation":false,"usgs":true,"family":"Hall","given":"R.E.","email":"","affiliations":[],"preferred":false,"id":372936,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Cousminer, H.L.","contributorId":59182,"corporation":false,"usgs":true,"family":"Cousminer","given":"H.L.","email":"","affiliations":[],"preferred":false,"id":372938,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stanton, R.W.","contributorId":19164,"corporation":false,"usgs":true,"family":"Stanton","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":372937,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Steinkraus, W.E.","contributorId":84509,"corporation":false,"usgs":true,"family":"Steinkraus","given":"W.E.","email":"","affiliations":[],"preferred":false,"id":372940,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
