MR 93 Cruz, E.L., and Cobb, E.H., , Map showing occurrences of antimony minerals in Alaska: U.S. Geological Survey Mineral Investigations Resources Map 93, 3 p., 1 sheet, scale ,, MR Uraniferous fluorspar deposits of Tertiary age are found mainly in Upper Ordovician and Middle Silurian dolomites. These fluorspar deposits, regarded as epi-thermal in origin, occur predominantly as breccia pipes in dolomite adjacent to faults and intrusive rhyolite breccia bodies. Minor occurrences are veins in dolomite, disseminations in volcanic rocks, and mineralized intrusive rhyolite.

    The activity of mining a mineral deposit covers four basic, inter-related stages. Initial identification of an area with a mineral deposit is exploration. The goal is to locate a concentration of a mineral commodity and to define its inherent value in general terms. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion.

Geologic Setting The purpose of this chapter is to document the geology and mineral resources of the North-Central Idaho Sagebrush Focal Area (“study area”), which extends from east-central to. The shifting of meandering and braided rivers across the landscape as a result of their own deposition of sediment produces a flattened, sediment-rich landscape known as a flood plain.

The photograph to the right shows the Rio Negro as seen from space: as you can see, the landscape is scarred with former meanders where the river used to flow before it shifted its bed.
