沉积（火山）岩中铅锌矿化与金矿化的关系——兼论我国铅锌矿化集中区的金矿勘查

近年来，我国在铅锌矿区或外围发现了越来越多不同类型的金矿床，铅锌矿化与金矿化之间的相互关系及其勘查指示意义已引起了广泛的关注。沉积（火山）岩中的铅锌矿化基本可分三种类型，不同类型的铅锌矿化有不同的成矿环境，而金的成矿地质事件是在特定地区与特定的热—构造事件相互耦合的。研究发现，只有在经历了后期强烈的热—构造事件的Sedex型或VMS型铅锌矿区才具备形成金矿化的条件，是金矿勘查的有利地区；MVT型和后期缺乏热—构造事件的Sedex型或VMS型铅锌矿区不具备形成金矿化的条件，是金矿勘查的不利地区。

Exploration Indication of Gold Deposits: the Lead Zinc and Gold Mineralization in (Volcano-) Sedimentary Rocks and Their Relationship

More and more large scale sediment hosted gold deposits are discovered and explored in Pb Zn ore field in China to which a extensive attention has bee n paid. (Volcano )Sediment hosted Pb Zn deposits can be divided into three ty pes :(1)MVT,(2)VMS ,and (3)Sedex type which occur in given tectonic settings,respe ct ively. And gold mineralization is linked to a special thermo tectonic event. Th e i ntensive research showes that sediment hosted gold deposits are only formed in t he region with late extensive thermo tectonic event in which the Sedex and VM S type Pb Zn deposits are occurred ,but MVT does not.So,the region located Sedex and VMS type deposits are the favourable prospects for gold deposits,and MVT h os ted region is not.
