块状硫化物矿床的一个重要特征是与长英质火山岩密切相关.这种成因关系是找矿的基础.但大部分长英质火山岩无矿,有这种火山岩存在并不能保证找矿成功.若能找出某些方法鉴别含矿与无矿长英质火山岩,则可缩小找矿靶区. 岩浆的化学性质是受其发生和发展过程控制的.若含矿与无矿火山岩有不同的成因历史,则其差别就应反映到岩石化学性质上为了证明这一假说,加拿大多伦多大学已开始这一研究项目,目的在于以岩石化学为基础区分含矿与无矿长英质火山岩.可惜这里与铜锌块状硫化物矿床
An important feature of massive sulphide deposits is closely related to the Ordovician volcanic rocks, which are the basis for prospecting, but most of the Ordovician volcanic rocks are non-mineable. The existence of such volcanic rocks does not guarantee the prospecting success. If some methods can be identified to identify ore-bearing and non-ore-bearing quartz volcanic rocks, the ore-prospecting target can be narrowed.The chemical properties of magma are controlled by its occurrence and development process.If ore-bearing and ore-free volcanic rocks are different Origin of the history, the difference should be reflected in the petrochemical nature To prove this hypothesis, the University of Toronto has begun this research project, the purpose is to distinguish between petrochemical based ore-bearing and non-mine quartz volcanic rocks. And Cu-Zn massive sulfide deposits
