Detailed mapping has shown that the carbonate rocks of Cambrian and Ordovician age in the Lancaster quadrangle, Pennsylvania, can be divided into 14 rock-stratigraphic units. These units are defined primarily by their relative proportions of limestone and dolomite. The oldest units, the Vintage, Kinzers, and Ledger Formations of Cambrian age, and the Conestoga Limestone of Ordovician age are retained in this report. The Zooks Corner Formation, of Cambrian age, a dolomite unit overlying the Ledger Dolomite, is named here for exposures along Conestoga Creek near the village of Zooks Corner. The Conococheague (Cambrian) and Beekmantown (Ordovician) Limestones, as mapped by earlier workers, have been elevated to group rank and subdivided into formations that are correlated with and named for geologic units in Lebanon and Berks Counties, Pa. These formations, from oldest to youngest, are the Buffalo Springs, Snitz Creek, Millbach, and Richland Formations of the Conococheague Group, and the Stonehenge, Bpler, and Ontelaunee Formations of the Beekmantown Group. The Annville and Myerstown Limestones, which are named for lithologically similar units in Dauphin and Lebanon Counties, Pa., overlie the Beekmantown Group in one small area in the quadrangle.

Soundings were made on the northwestern part of the island of Oahu near the town of Waialua and on the island of Hawaii on the \"saddle\" area near Pohekuloa and the Humuula sheep station. On Oahu, the geoelectrical study indicates that correlation among four stratigraphic units underlain by a vesicular basalt basement is possible. The electrical soundings indicate that it is feasible to determine the approximate depth to the fresh-saline water interface within the basalt. Two Schlumberger soundings with electrode spacings, AB/2, reaching 6,000 feel give sounding curves of the maximum and minimum type whose terminal branches indicate that the true resistivity of basalts saturated with sea water, in the survey area on Oahu, is about 30-40 ohm-m. On the island of Hawaii, an exploratory well drilled in basalt to a depth of 1,001 feet proved to be dry. In the area of this well, two deep soundings were made using the Schlumberger and the equatorial arrays. Although additional soundings at various orientations and larger spacings are needed, there appears to be a conductive layer below 1,600 feet which may represent basalt saturated with fresh water.

Together with thermal properties measurements made on the core, and additional temperature measurements in progress these data will he used to estimate geothermal flu: from the area. The purpose of this interim report is to make our preliminary temperature measurements available to other interested groups.
The locations of the sites are shown on figure 1, and data pertinent to the state of disequilibrium at the time of measurement are tabulated in table 1. In the geothermal profiles (figs. 2 through 13) the temperature is given in decrees centigrade and the depth (Z) in meters.

Similarly altered water-washed tuff occurs as tongues in the uppermost part of this member, and forms most of the lower 400-600 feet of the overlying Evacuation Creek Member of the Green River Formation. \r\n\r\n'The altered ash-fall beds of the Parachute Creek Member are all thin and show a characteristic pattern of alteration. Most beds range in thickness from a fraction of an inch to a few inches. One bed reaches a maximum thickness of 5 feet, and, unlike the other beds, is composed of several successive ash falls. The pattern of alteration changes from the outer part to the center of the basin. Most beds in the outer part of the basin contain about 50 to 65 percent analcite,with the interstices between the crystals filled mainly by microlites of feldspar, opal, and quartz, and small amounts of carbonate. At the center of the basin .essentially all the beds -are composed of microlites of feldspar, opal, and quartz, and small amounts of carbonate. The tongues of water-washed tuff in the uppermost part of the Parachute Creek Member and the similar rocks composing the lower 400-600 feet of the Evacuation Creek Mewber are feldspathized rocks composed mainly of microlites of feldspar, opal, and quartz, varying amounts of carbonate, and in some specimens tiny subrounded crystals of analcite. \r\n\r\nThe general trend in alteration of the tuffaceous rocks from analcitization near the margin to feidspathization near the center of the Piceance Creek Basin is believed to have taken place at shallow depth during diagenesis , as indicated by field observations and laboratory work. It is believed that during sedimentation and diagenesis the waters of the central part of the basin were more alkaline and following the breakdown of the original tuffaceous glass to a colloidal gel during diagenesis analcitized rocks crystallized near the basin margin and feldspathized rocks crystallized near the center of the basin.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr68113","usgsCitation":"Griggs, R.L., 1968, Altered tuffaceous rocks of the Green River Formation in the Piceance Creek Basin, Colorado: U.S. Geological Survey Open-File Report 68-113, Report: ii, 38 p.; 3 Plates: 23.73 x 26.29 inches, https://doi.org/10.3133/ofr68113.","productDescription":"Report: ii, 38 p.; 3 Plates: 23.73 x 26.29 inches","costCenters":[],"links":[{"id":492933,"rank":6,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_8249.htm","linkFileType":{"id":5,"text":"html"}},{"id":145386,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1968/0113/report-thumb.jpg"},{"id":42548,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1968/0113/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42549,"rank":4,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1968/0113/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42550,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1968/0113/plate-3.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":42551,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1968/0113/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Colorado","otherGeospatial":"Green River Formation in the Piceance Creek Basin","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -108.667,\n 40\n ],\n [\n -108.667,\n 39.227\n ],\n [\n -107.942,\n 39.227\n ],\n [\n -107.942,\n 40\n ],\n [\n -108.667,\n 40\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db686872","contributors":{"authors":[{"text":"Griggs, Roy Lee","contributorId":54170,"corporation":false,"usgs":true,"family":"Griggs","given":"Roy","email":"","middleInitial":"Lee","affiliations":[],"preferred":false,"id":168614,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":46245,"text":"ofr6891 -
