Pelagic foraminifer replaced by barite and filled with apatite and pyrite. Fragments of other foraminifer tests also are visible. Globular body at left is a section of either a foraminifer chamber or a radiolarian filled with barite and containing two pyrite crystals. Enlargement X 100. Custer County, South Dakota, ca. 1967. (Photomicrograph) Middle portion published as plate 2, figure 7 in U. S. Geological Survey. Professional paper 594-L. 1968.

Contact between Niobrara Formation (above) and Carlile Shale (below) at a locality about k miles south of Fairburn in the NW 1/4, SE 1/4, sec. 13, T. 5 S., R. 7 E. The phosphate nodules are in the bed at the head of the hammer. The matrix of the bed consists of pyrite, mostly oxidized to yield iron oxides and gypsum. Custer County, South Dakota. Circa 1967. Published as figure 3 in U. S. Geological Survey Professional Paper 594-L. 1968.

Bed of lignite in the lower part of the upper phase of the bauxite-kaolin zone at Little Hope Crossroads. Looking north 3 1/2 miles west of Falkner, SW 1/4, NW 1/4, sec. 5, T. 3 S., R. 3 E. Tippah County, Mississippi. October 30, 1943.

Close-up of photo no. 6 showing the deposition of clay balls and breccia from the contemporaneous erosion of a laminated clayey silt bed. Looking east, 6 miles northwest of Ripley, SE 1/4 sec. 29, T. 3 S., R. 3 E. Tippah County, Mississippi. November 17, 1942.

Attaching new stellite bit to outer barrel of a double-barrel core barrel. Drill rods at left are size "A". The core barrel is 13 feet long, and will take a 11-foot core. Inside diameter of inner barrel about 2 1/4 inches. Outside diameter of outer barrel is about 3 inches. Equipment of the Pennsylvania Drilling Co. Tippah County, Mississippi. May 1943.

Part of cross section of nodule-bed specimen. Specimen from locality pictured in photo no. tah00033. Most of the ooids are replaced with pyrite. The veins in the nodules are filled mostly with pyrite that extends into the matrix. Calcite incorporates pyrite in some parts of the veins, and some of the pyrite has altered to gypsum. The light-gray mineral surrounding fragments at the lower left of the nodule is pyrite. Custer County, South Dakota, ca. 1967. Published as figure 7 in U. S. Geological Survey. Professional paper 594-L. 1968.

Part of cross section of nodule-bed specimen. Specimen from locality pictured in photo no. tha00033. Many small nodules and fragments of fish teeth and bones make up groundmass of the larger nodules. The matrix is cemented with pyrite, much of which has altered to iron oxides and gypsum along bottom and top of bed. The light-colored streak at the left is ferruginous gypsum. Custer County, South Dakota. Circa 1967. Published as figure 5 in U.S. Geological Survey Professional Paper 594-L. 1968.
thumbnail
Making a trip with a Longyear diamond drill using a fishtail bit. Note string of tools in the hole hanging on a wrench caught on the end of the rig skid. The uppermost joint of rod, with water hose attached, is resting on the board to the right of the hole. Equipment of the Pennsylvania Drilling Co. Tippah County, Mississippi. May 1943.

Nodules from U, S. Geological Survey Mesozoic loc. D3757 that show recognizable but not identifiable traces of fossils and irregular lumpy nodules that do not reveal traces of fossils. First specimen second row from bottom is a fragment of baculite. Bottom specimens are pelecypods. Custer County, South Dakota. Circa 1967. Published as figure 6 in U.S. Geological Survey Professional Paper 594-L. 1968.
