Unconformities separate a basal complex, two sequences of highly folded igneous and sedimentary rocks, and a younger sequence of gently dipping sedimentary rock. The basal Bermeja complex contains serpentinite, silicified porphyritic volcanic rock with some sedimentary rock, and minor spilite, amphibolitized spilite, and amphibolite. It is exposed chiefly in some anticlinal cores in southwestern&nbsp;</span><span class=\"ScopusTermHighlight\">Puerto</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">Rico</span><span>. Limestone, mudstone, andesite, and basalt form the older folded sequence. The Río Loco formation, bronzite andesite porphyry in part with pillow structures, was extruded perhaps in the Cenomanian. The&nbsp;</span><span class=\"ScopusTermHighlight\">Mayagüez</span><span>&nbsp;group includes most of the rocks in southwestern&nbsp;</span><span class=\"ScopusTermHighlight\">Puerto</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">Rico</span><span>: the Yauco mudstone, Parguera limestone, Brujo limestone, Melones limestone, Maricao basalt, Sabana Grande andesite, and El Rayo volcanic rocks. The maximum possible age range is Turonian to Maestrichtian. The group ranges in thickness from about 800 m in the south to 3800 m in the north, and it varies in lithology from limestone in the south to mudstone and volcanic rock in the north, indicating a volcanic center to the north during that time. The second folded sequence contains andesitic volcanic rock, bedded tuff, and massive limestone. The San Germán formation (Maestrichtian) includes andesite, the Cabo Rojo agglomerate member, and the Cotui limestone member. The Jicara formation, massive limestone and bedded tuff, is Paleocene; there is one exposure of an unnamed ? Eocene marl. Post-Eocene limestone and conglomerate are also exposed in the&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>. The structure of the basement complex is obscured by its massiveness and by the cover of younger rocks. Two major deformations have affected the rocks of southwestern&nbsp;</span><span class=\"ScopusTermHighlight\">Puerto</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">Rico</span><span>&nbsp;since Cenomanian to Santonian time. In the Maestrichtian, the first of these formed folds with a N. 60° W. trend, asymmetric or overturned to the south. Near the south coast the folding of thin&nbsp;</span><span class=\"ScopusTermHighlight\">Mayagüez</span><span>&nbsp;group rocks was probably influenced by trends in the Bermeja complex which caused deviations in the regional trends and also some overturning to the north. The San Germán formation, deposited unconformably on the eroded surface of the folded&nbsp;</span><span class=\"ScopusTermHighlight\">Mayagüez</span><span>&nbsp;group, contains large allochthonous blocks of older and contemporaneous rocks. These blocks, up to 2 km by 1 km in exposure, were deposited by slumping or sliding due to gravity within and at the base and top of the San Germán formation near Lajas and San Germán. Most rocks in the blocks are extremely contorted and contain deformed Foraminifera. The San Germán and Jicara formations and perhaps the ?Eocene marls were deformed into gentle open folds trending east in the&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>&nbsp;covered by this report. Oligocene, Miocene, and younger sedimentary rocks have been tilted and uplifted. Large east-west left-lateral transcurrent faults cross the&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>, offsetting and offset by two sets of transverse faults (N. 45° E., N. 20° W.): most faults are probably Maestrichtian to Oligocene, although minor faulting has continued to the present. Dikes and sills of quartz diorite porphyry and mica-quartz dacite porphyry intrude the ?Maestrichtian San Germán formation and older units. A diorite plug cuts the Bermeja complex, and a granodiorite plug intrudes the&nbsp;</span><span class=\"ScopusTermHighlight\">Mayagüez</span><span>&nbsp;group.&nbsp;</span></p>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1960)71[319:GOTMAP]2.0.CO;2","usgsCitation":"Mattson, P.H., 1960, Geology of the Mayagüez area, Puerto Rico: Bulletin of the Geological Society of America, v. 71, no. 3, p. 319-362, https://doi.org/10.1130/0016-7606(1960)71[319:GOTMAP]2.0.CO;2.","productDescription":"44 p.","startPage":"319","endPage":"362","costCenters":[],"links":[{"id":385772,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United  States","otherGeospatial":"Puerto Rico","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -67.52197265625,\n              17.832374329567518\n            ],\n            [\n              -65.302734375,\n              17.832374329567518\n            ],\n            [\n              -65.302734375,\n              18.58377568837094\n            ],\n            [\n              -67.52197265625,\n              18.58377568837094\n            ],\n            [\n              -67.52197265625,\n              17.832374329567518\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"71","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Mattson, Peter H.","contributorId":72659,"corporation":false,"usgs":true,"family":"Mattson","given":"Peter","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":816069,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Data published on the&nbsp;</span><span class=\"ScopusTermHighlight\">East</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">Tintic</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">district</span><span>&nbsp;by the Survey and others were studied and map data made available from various mining companies were compiled. Preliminary economic studies were made to determine the present day value of the type of ore body discovered previously in the&nbsp;</span><span class=\"ScopusTermHighlight\">district</span><span>. Encouraging results from these investigations led to the selection of specific targets for exploration. Recommendations for&nbsp;</span><span class=\"ScopusTermHighlight\">a</span><span>&nbsp;project program were made and approved. Negotiations were successfully concluded in mid-1956 for&nbsp;</span><span class=\"ScopusTermHighlight\">a</span><span>&nbsp;unit lease agreement on lands in the&nbsp;</span><span class=\"ScopusTermHighlight\">East</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">Tintic</span><span>&nbsp;</span><span class=\"ScopusTermHighlight\">district</span><span>&nbsp;owned by the&nbsp;</span><span class=\"ScopusTermHighlight\">Tintic</span><span>&nbsp;Standard and&nbsp;</span><span class=\"ScopusTermHighlight\">Chief</span><span>&nbsp;Consolidated mining companies and their subsidiaries. Of the targets selected for exploration, the&nbsp;</span><span class=\"ScopusTermHighlight\">Chief</span><span>&nbsp;Oxide&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>&nbsp;seemed to be one of the most prominent. Our preliminary work in the&nbsp;</span><span class=\"ScopusTermHighlight\">Chief</span><span>&nbsp;Oxide&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>&nbsp;corroborated the findings of the U.S. Geological Survey described in Part I of this paper. After careful consideration it was decided to gamble the cost of an exploration shaft in this&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>&nbsp;for the purpose of providing an underground drilling platform. We also hoped by means of underground workings to establish the existence and nature of the postulated fault.&nbsp;</span><span class=\"ScopusTermHighlight\">A</span><span>&nbsp;limited amount of surface drilling was done prior to shaft sinking in order to locate&nbsp;</span><span class=\"ScopusTermHighlight\">a</span><span>&nbsp;shaft site and also to obtain additional information of subvolcanic structure and alteration. Underground exploration in the&nbsp;</span><span class=\"ScopusTermHighlight\">Chief</span><span>&nbsp;Oxide&nbsp;</span><span class=\"ScopusTermHighlight\">area</span><span>&nbsp;was started in January, 1957. The Burgin shaft was sunk to&nbsp;</span><span class=\"ScopusTermHighlight\">a</span><span>&nbsp;depth of 1,100 feet and by August, 1959, lateral development on the 1050 level totaled 4,721 feet and underground diamond drilling totaled 15,480 feet.

Iron-zinc ratios in sphalerite indicate that the ore minerals were deposited at a temperature between 425°C and 740°C. This temperature is within the range of the temperatures at which topaz, a comman associate of the ore minerals, has been synthesized in the laboratory. The temperature of deposition of the ore minerals is above the temperature interval in which clay minerals are stable. Thus, clay minerals could not have formed while ore was being deposited. As temperatures fell and entered the stability range of the clay minerals, argillic alteration encroached upon greisen ores and wall rocks. Reaction rims between quartz and topaz indicate that kaolinite could have formed according to the following reaction: topaz + quartz + water + limestone -* kaolinite + fluorite + Cajj\"C (Al,F)2Si04 + Si02 +3H2O+ CaCOa - Al2Si20B(OH)41 + CaF2 + H2CO3 The clay minerals, which formed from diverse rock types, consist of kaolinite, dickite, mixed-layered chlorite-montmorillonite, and minor montmorillonite, accompanied by variable amounts of muscovite and zinnwaldite. The dickite is most common in and near late veins that cut the earlier-formed greisen. Temperature is believed to be the principal agent governing the relations between ore deposition and&nbsp;</span><span class=\"ScopusTermHighlight\">argillization</span><span>. Similar relations are to be expected in other high-temperature deposits where abundant veining and fracturing indicate that wall rocks reached an isothermal condition above a maximum temperature of 480°C during ore deposition.&nbsp;</span></p>","language":"English","publisher":"Society of Economic Geologists","doi":"10.2113/gsecongeo.55.7.1478","usgsCitation":"Sainsbury, C., 1960, Metallization and post-mineral hypogene argillization, Lost River tin mine, Alaska: Economic Geology, v. 55, no. 7, p. 1478-1506, https://doi.org/10.2113/gsecongeo.55.7.1478.","productDescription":"29 p.","startPage":"1478","endPage":"1506","costCenters":[],"links":[{"id":385669,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United  States","otherGeospatial":"Bering land bridge","volume":"55","issue":"7","noUsgsAuthors":false,"publicationDate":"1960-11-01","publicationStatus":"PW","contributors":{"authors":[{"text":"Sainsbury, C.L.","contributorId":99968,"corporation":false,"usgs":true,"family":"Sainsbury","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":815737,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
