Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Reference): Primary Reference = Karl, 1992

Comment (Deposit): Model Name = Disseminated sulfide minerals in trondhjemite.

Comment (Geology): Geologic Description = The country rock in the area of this site is Silurian trondhjemite that locally is sheared and sericitized, probably owing to Upper Cretaceous, greenschist-grade regional metamorphism (Berg, 1972 [I 684]). The occurrence consists of sparse base-metal sulfide mineralization in the trondhjemite, and is based on a sample of trondhjemite containing Cu-Pb-Zn sulfide minerals collected by a road construction crew in 1990 (Karl, 1992, loc. 17).
