The scheelite deposit on the west slope of the Paradise Range, in northwestern Nye County, Nevada (Fig. 1), is of interest because of the association of scheelite in a vein with an abundance of the unusual chlorite leuchtenbergite. In western Nevada and nearby portions of southern California, scheelite has been found in contact-metamorphic deposits,1 in pegmatites,2 and in quartz veins.3 Each type has furnished scheelite of economic importance, although the contact-metamorphic deposit at Mill City, Nevada, has been the outstanding producer in the United States in recent years. The scheelite-leuchten-bergite vein in the Paradise Range has yielded only a small production.
The scheelite vein (Figs. 2, 3; Pl. 181, fig. 1) is on the crest of a ridge in sec. 36, T. 12 N., R. 36 E., and the vein and adjacent ground are included in two patented claims, Betty O'Neil No. 1 and No. 2, together with a . . .
