Radiating intergrowths of quartz (white) and ferruginous rhodochrosite (gray) with small patches of finely divided sulphides (black); photomicrograph (ordinary light) of this thin section of ore from 1000-foot level, Belmont vein. Nye County, Nevada. 1915. Plate 6- A in U.S. Geological Survey. Professional paper 104. 1918.

Electrum showing crystal outlines associated with quartz and sulphides. The argentite was very probably formed by the replacement of galena, but all the other minerals are believed to be alpha hypo gene. Photomicrograph of polished surface of ore from 1,260- foot level, Murray vein, Tonopah Extension mine. Nye County, Nevada. 1915. Plate 5- B, with graphics, in U.S. Geological Survey. Professional paper 104. 1918.

Album caption:Fission-track map (photograph) of uranium distribution in the Grouse Canyon Member of the Belted Range Tuff. Core UE12P#1 sampled at 389.2 m in densely welded tuff. The glassy matrix shows uniform uranium distribution but heterogeneous uranium distribution occurrs in pumice (upper right), magnetite rims (upper left) and along borders of matrix and pumice (lower right). Nye County, Nevada. n.d. Published as figure 2-B in U.S. Geological Survey. Journal of research, v. 6, no. 4, July-August 1978, p. 489-498.

Album caption:Fission-track map (photograph) of uranium distribution in the Grouse Canyon Member of the Belted Range Tuff. Surface sample of densely welded tuff. Uranium distribution is homogenous in glassy matrix but inhomogeneous in pumice (upper) and in manganese oxides surrounding a plagioclase lath (lower). Nye County, Nevada. n.d. Published as figure 2-A in U.S. Geological Survey. Journal of research, v. 6, no. 4, July-August 1978, p. 489-498.

Electrum (stippled) irregularly intergrown with sphalerite and quartz; the argentite shown in this photograph was probably formed by the replacement of (beta hypo gene) of galena all the other minerals, including the electrum, are believed to be alpha hypo gene; Photomicrograph of polished surface of ore from 1,050-foot level, Macdonald vein, North Star Mine. Nye County, Nevada. 1915.

Album caption:Fission-track map (photograph) of uranium distribution in the Grouse Canyon Member of the Belted Range Tuff.Core UE12P#1 sampled at 389.8 m in zeolitized tuff.Uranium distribution is in many tiny point sources which correspond to iron oxide concentrations.Some uranium in this sample was remobilized during epoxy impregnation.Uraniferous debris collected in airbubble pits which were transected during production of the thin section.Resultant pits also appear as uranium hotspots. Nye County, Nevada. n.d. Published as figure 2-C in U.S. Geological Survey. Journal of research, v. 6, no. 4, July-August 1978, p. 489-498.
