The Climax mine contains three molybdenite ore bodies and widespread late quartz-pyrite-sericite barren mineralization, each related to separate intrusive phases of the Climax stock. Alteration zones spatially related to each molybdenite ore body inc

The ores at Darwin occur as massive replacement bodies in silicated limestones of Pennsylvanian and Permian age adjacent to a Jurassic quartz monzonite stock. Three types of ore have a definite spatial relationship to the quartz monzonite: (1) pyrite

Minor element abundances were determined for galena and sphalerite from the Darwin mine, Inyo County, California. The temperature of deposition was calculated from the distribution coefficients determined experimentally by Bethke and Barton (1971) fo

The writers determined $$\delta O^{18}$$ and $$\delta C^{13}$$ of coexisting limestone and dolomite samples from several localities in the upper Mississippi Valley zinc-lead district and found little fractionation in mineral pairs. This is in conflic

This paper presents data on the distribution of minor elements in ore and gangue minerals and in adjacent host rock from the Illinois-Kentucky fluorite district and Upper Mississippi Valley zinc-lead district. Comparisons are made of the minor-elemen

The Wood River lead-silver deposits, near Bellevue in south-central Idaho, occur in veins in sheared zones in contact metamorphosed siliceous and limy argillites of Mississippian age near contacts with quartz diorite. Galena and sphalerite are the pr
