| 摘 要： | 查干布拉根银铅锌（金）矿床是大型低硫化型浅成低温热液矿床,区域上受北东向裂谷型得尔布干断裂带及次级北西向断裂控制,矿床形成于燕山晚期大面积火山岩喷发及次火山岩侵位之后热 活动期,矿术具有独特的矿物组合与蚀变分带,主成矿元素分带明显,主要受北西西向断裂及其下盘的火山通道所制约,矿床形成深度较浅,剥蚀程度较低。

| Abstract: | Chaganbulagen Ag, Zn(Au) deposit is a large type epithermal deposit of low sulfidation. It is controlled by NE-striked De' erbugan fracture zone and its secondary NW trending faults. The deposit was formed in the stage of hydrothermal activity after a large- scale volcanic eruption and subvolcanic emplacement in Late Yangshanian period. The main ore -forming elements show clear zonation. The deposit is of special mineral assemblages and alteration zonation, which is controlled by NWW striking faults and footwall volcanic vent. The forming depth of the deposit is quite shallow and it didn' t undergo intensive denudation. Therefore, its geological features are well preserved |
