论德尔尼黄铁矿型铜 钴矿床的地质特征及其与塞浦路斯铜矿的区别

通过对德尔尼铜 钴矿床与塞浦路斯铜矿的对比，进一步明确了德尔尼铜 钴矿床为与印支期黑云花岗岩有成因联系的岩浆热液矿床。矿区的超基性岩或超基性火山角砾岩都是不含矿的，与矿床无成因联系；底辟上升侵位也不存在。将德尔尼铜 钴矿床作为火山岩块状硫化物矿床系列中的最基性端员缺乏依据。

GEOLOGICAL CHARACTERISTICS OF DEERNI PYRITE TYPE COPPER/COBALT DEPOSIT AND ITS DIFFERENCE FROM CYPRUS COPPER DEPOSIT

Comparison of the Deerni copper/cobalt deposit with the Cyprus copper deposit futher confirms that the former represents a magmatic hydrothermal deposit having a genetic relation to the biotite granitization during the Indo Chinese epoch. A genetic tie with the ultrabasic rock or ultrobasic volcanic breccia has not so far been seen nor the diapiric emplacement of these rocks. Therefore, the argument of the Deerni diposit for the most basic member of volcanic massive sulfide deposit series is somewhat groundless.
