| Abstract/Notes | Mineralogical, f luid inclusion, and geochemical studies of precious metal mineralization within the Baimka trend in the western Chukchi Peninsula have been preformed. Porphyry copper–molybdenum– gold deposits and prospects of the Baimka trend are spatially related to monzonitic rocks of the Early Creta- ceous Egdygkych Complex. Four types of precious metal-bearing assemblages have been identified: (1) chal- copyrite + bornite + quartz with high-fineness native gold enclosed in bornite, (2) low-Mn dolomite + quartz + sulfide (chalcopyrite, sphalerite, galena, tennantite-tetrahedrite) ± tourmaline with low-fineness native gold and hessite, (3) rhodochrosite + high-Mn dolomite + quartz + sulfide (chalcopyrite, sphalerite, galena, ten- nantite-tetrahedrite) with low-fineness native gold, electrum, acanthite, Ag and Au–Ag tellurides, and Ag sulfosalts, and (4) calcite + quartz + sulfide (chalcopyrite, sphalerite, galena) with low-fineness native gold, Ag sulfides and selenides, and Ag-bearing sulfosalts. Study of f luid inclusions from quartz, sphalerite, and f luorite have revealed that hydrothermal ores within the Baimka trend precipitated from f luids with strongly variable salinity at temperatures and pressures ranging from 594 to 104oC and from 1200 to 170 bar, respec- tively. An indicator of vertical AgPbZn/CuBiMo geochemical zoning is proposed. The value range of this indicator makes it possible to estimate the erosion level of the porphyry–epithermal system. The erosion level of the Baimka deposits and prospects deepens in the following order: Vesenny deposit → Pryamoi prospect → Nakhodka prospect → Peschanka deposit → III Vesenny prospect. | ||
