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 (Deposit): Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a)

Comment (Geology): Geologic Description = The area of this occurrence is underlain by Middle Triassic to Upper Pennsylvanian interbedded black argillite and volcanic sandstone. The upper part of sequence contains about 100 of radiolarian chert. The sequence is cut by numerous diabasic and gabbroic dikes (Wilson and others, 1998). The occurrence consists of pyrite and chalcopyrite disseminated in the bedded rocks, and of secondary malachite.

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Saunders, 1961

Comment (Workings): Workings / Exploration = Surface sampling only.

Comment (Geology): Age = the sulfide minerals probably are syngenetic with their Triassic-Upper Pennsylvanian host rocks.
