Abstract
The Mugeug gold deposits is consisted of more than fourteen gold and silver-bearing quartz veins emplaced in Mesozoic granodiorite mass. In the Samhyungje vein, one of the representative vein in the mine, six stages of mineralizatidns are recognized: Stage I, deposition of base-metal sulfides and gray quartz; stage II, deposition of base-metal sulfides, electrum and white quartz with pinkish tint; stage m, deposition of base-metal sulfides and dark gray quartz; stage N, deposition of native silver, argentite, Ag-tetrahedrite, polybasite, arsenpolybasite and quartz; stage V, deposition of nearly barren quartz; stage VI, deposition of transparent quartz veinlets with minor pyrite. Ag contents of electrum increase steadily from stage II to stage N; 57.25-61.44 atom. % for stage II, 62.85-69.66 atom. % for stage m, 69.79-74.12 atom. % for stage N. Homogenization temperatures of fluid inclusions are as follows; stage II, from
