摘要
可可塔勒矿床位于新疆阿尔泰造山带南缘,产于泥盆纪火山-沉积盆地内铅锌矿(可可塔勒)体呈似层状、透镜状,矿石构造以条纹条带状、块状、斑杂状为主,矿物成分相对简单,矿体直接容矿围岩为火山-沉积岩。矿床属火山-沉积岩容矿的块状硫化物矿床。为介于典型的火山岩容矿的块状硫化物型矿床(VHMS)和典型沉积岩容矿的硫化物矿床(SEDEX型)之间的过渡类型(一种新类型块状硫化物矿床),其矿化特征与伊比利亚型矿床相类似。
Keketale Pb-Zn deposit is located in the south margin of the Altay orogenic belt. The ore bodies in the Devonian volcano-sedimentary basin occur in stratiform and lens shapes, and are closely hosted in volcanic-sedimentary rocks. Ore structures are predominantly banded, massive and mottled textures with relatively simple ore mineral composition. It is suggested that the deposit belongs to a volcanic-sedimentary rock-hosted massive sulfide deposit, i. e. , a new-type massive sulfide deposit or an intermediate type between typical volcanic rock-hosted massive sulfide deposit ( VHMS type) and typical sedimentary exhalative deposit (SEDEX type). Mineralization characteristics are similar to that of “Iberian-type” deposits.
