Theses, Ph.D., imprint []. Uranium never occurs as bare metal; rather, it most often occurs in oxides as the minerals uraninite (UO 2) or pitchblende (partially oxidized uraninite, conventionally given as U 3 O 8).In solution, uranium travels in molecular complexes with carbonate, sulfate and chloride as long as the chemical conditions are oxidizing. But under reducing conditions, uranium drops out of solution as oxide Author: Andrew Alden.

A Tertiary mountain-building episode is responsible for the uplift and current topography of the Black Hills region. This uplift was marked by volcanic activity in the northern Black Hills. The southern Black Hills are characterized by Precambrian granite, pegmatite, and metasedimentary rocks that comprise the core of the entire Black Hills uplift.

A coarse-grained, pink to salmon-coloured granitic pegmatite, with much quartz-feldspar intergrowth ("graphic granite") and impressive pink perthitic alkali feldspar (probably microcline), smoky quartz, and traces of the iron oxide attractive grey wash in the quartz may be due to low-intensity radiation damage.
