摘要
GOLD mineralization and Sedex-type base metal mineralization (SBM) have been separately studied for along period. This may lead geologists to ignore the important exploration meaning of SBM in goldprospecting. A typical example is related to the Carlin-type gold ore deposits, in the study of which, Hg,As, Sb and other mineralizations have been stressed but SBM has been ignored. 1 A new phenomenon In recent years, it has been discovered that many Carlin-type gold ores and SBM are distributed inthe same geology unit but are disjunctive each other. In Carlin district of USA, Emsbo et al.have reported the Sedex-type Pb-Zn orebody in thedepth of Meikle Au deposit, the same phenomenon has been described in Screamer, Golden April,
