Chemical analyses of coal and coal-associated rock samples from the Coalmont Formation, McCallum and Coalmont areas, North Park, Jackson County, Colorado

As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 44 coal and coal-associated rock samples were collected from the Paleocene and Eocene, Coalmont Formation in the McCallum and Coalmont areas, North Park, Jackson County, Colorado. Twenty-eight samples (24 coal and 4 coal-associated rock) are from the McCallum area and 16 samples (12 coal and 4 coal-associated rock) are from the Coalmont area. Locations of ten core holes and three mines where the samples were collected, and an outline of North Park are shown on figure 1. The 44 samples are briefly described in table 1.

Chemical analyses of deep core coal and shale samples from the Almond Formation, Washakie Basin, Sweetwater County, Wyoming

During gas and oil exploration efforts in the Washakie Basin in Sweetwater County, Wyoming, undertaken by Ladd Petroleum Co. (a subsidiary of Utah International Inc.) core from the Upper Cretaceous Almond Formation of the Mesaverde Group was collected from their 1-22 Federal well. (See figure 1 for location.) From this core three coal and two carbonaceous shale samples, orginally at depths ranging from 3,091 to 3,116 m (see table 1 for descriptions), were selected and given to the U.S. Geological Survey for study. Results of chemical analyses on the samples and a comparison of these analyses with analyses of near-surface Almond Formation coal samples in Carbon County, Wyoming, are the topics of this report.

Chemical analyses of coal from the Tongue River Member of the Fort Union Formation, Moorhead and southeastern part of the northward extension of the Sheridan coal fields, Powder River and Big Horn counties, Montana

As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 83 samples were collected from 23 core holes in the Paleocene Tongue River Member of the Fort Union Formation in Big Horn and Powder River counties, Montana. These holes are located in the Montana part of the Powder River coal region, specifically in the western part of the Moorhead coal field and on the eastern margin of the Northward Extension of the Sheridan coal field (fig. 1)

Coal resource and coal quality of Pumpkin Creek EMRIA site, Powder River County, Montana: With a section on chemical analysis

The Pumpkin Creek EMRIA site, an area of about 94 square miles, is located mainly in the southwestern part of the Coalwood coal field on the slightly westward dipping beds of the Tongue River Member of the Paleocene Fort Union Formation in Powder River County, Montana. Three coal beds, A, Sawyer, and Mackin-Walker, were evaluated by 32 drill holes. Coal resources--measured, indicated, and inferred--within the site and in beds more than 5 feet thick are 191,660,000 short tons, 1,356,950,000 short tons, and 34,400,000 short tons, respectively. The coal has an apparent rank of lignite A as shown by the analyses of 17 core samples. The average Btu value of 15 core samples of the Sawyer from the site on the as-received basis is 6,970, average ash content is 6.8 percent, and average sulfur content is 0.4 percent. A comparison of the analyses of samples from the Sawyer coal bed with other analyses of Powder River region coal samples shows that moisture, hydrogen, and oxygen contents are significantly higher, and volatile matter, fixed carbon, carbon, nitrogen, and total sulfur contents and heat of combustion are significantly lower in the Sawyer bed samples. A statistical comparison of the elemental compositions of the two sample groups shows that the Sawyer bed has significantly higher contents of B, Ba, Mn, Nb, U, Y, and Yb and significantly lower contents of Be, Co, Cr, Cu, Ni, Pb, Sc, Se, and Th. The sample of the lower split of the Sawyer bed (bed A) in drill hole PWW8 has a relatively high sulfur content of 1.7 percent, and presumably would not be mined with the rest of the Sawyer. The Mackin-Walker has a Btu value of 7,220, an ash content of 6.9 percent, and a sulfur content of 1.0 percent.

Montana

Chemical analyses of coal from the Tongue River Member, Fort Union Formation, Decker coal deposit, Big Horn County, Montana

As part of a continuing cooperative program between the U. S. Geological Survey and the Montana Bureau of Mines and Geology to collect and chemically analyze representative samples of Montana coals, 50 coal and 2 carbonaceous shale samples were collected from the Anderson, Dietz 1 and Dietz 2 coal beds in the Paleocene Tongue River Member of the Fort Union Formation. These samples were collected at six locations in sections 9 and 15, T. 9 S., R. 40 E., section 26, T. 8 S., R. 39 E., and section 29, T. 9 S., R. 39 E., Big Horn County, Montana.

Geology and coal resources of the Hanging Woman Creek Study Area, Big Horn and Powder River Counties, Montana

In an area of 7,200 acres (29 sq km) In the Hanging Woman Creek study area, the Anderson coal bed contains potentially surface minable resources of 378 million short tons (343 million metric tons) of subbituminous C coal that ranges in thickness from 26 to 33 feet (7.9-10.1 m) at depths of less than 200 feet (60 m). Additional potentially surface minable resources of 55 million short tons (50 million metric tons) are contained in the 9-12 foot (2.7-3.7 m) thick Dietz coal bed which lies 50-100 feet (15-30 m) below the Anderson. Analyses of coal from 5 core holes indicates that the Anderson bed contains 0.4 percent sulfur, 5 percent ash, and has a heating value of 8,540 Btu/lb (4,750 Kcal/kg). The trace element content of the coal is generally similar to other coals in the Powder River Basin. The two coal beds are in the Fort Union Formation of Paleocene age which consists of sandstone, siltstone, shale, coal beds, and locally impure limestone. A northeast-trending normal fault through the middle of the area, downthrown on the southeast side, has displaced the generally flat lying strata as much as 300 feet (91 m). Most of the minable coal lies northwest of this fault.

Chemical analyses of coal and shale from the Wasatch Formation in core hole B-1, city of Buffalo, Johnson County, Wyoming

During 1975, a continuous core (B-1) was taken through the uppermost 132.9 m (430 ft) of soil and rock underlying Buffalo, Wyo. The NX (7.6-cm (3in.)) bore hole is located in the NE 1/4 of the NW 1/4 of sec. 35, T. 51 N., R. 82 W., Johnson County, Wyo. (See index map in fig. 1.) The first 5.3 m (17.4 ft) was sampled by Shelby tube, the remainder by wire-line coring apparatus using a split inner tube. Bentonite-based drilling mud was used to drill that part of the hole below 30 m (98 ft). The core was preserved in approximately 15-cm (5.8-in.) lengths in sealed glass jars (Farrow, 1976).
