块状硫化物矿床的形成离不开岩浆分异吗?——与姜齐节、秦克章等人商榷

认为块状硫化物矿床在成因方面实际上是多种多样的，与成矿有关的火山岩常常是双峰式火山岩组合，它们可能来自于不同的岩浆源区而与岩浆分异作用没有必然的联系。

MASSIVE SULFIDE DEPOSITS AND MAGMATIC DIFFERENTIATION

During the past few years, it was held that magmatic differentiation is indispensable for massive sulfide deposits. The recent study has revealed that a lot of volcanogenic massivesulfide deposits are related to bimodal volcanic rocks. For the Ashele deposit and its hostrocks, the basic volcanic rocks were originated from a mantle source, while the acidic volcanic rocks from a crust source. It indicates that there is no magmatic differentiation among the different kinds of volcanic rocks.A lot of other deposits are related only to basalts, without obvious magmatic differentiation. In general, different massive sulfide deposits have different relation to the volcanic rocks, and magmatic differentiation is not indispensable.
