内蒙古赤峰市官地银金矿床地质特征及成矿分析OACSTPCD
GEOLOGY AND METALLOGENY OF THE GUANDI ELECTRUM DEPOSIT IN CHIFENG, INNER MONGOLIA
官地银金矿床规模为中型矿床,产出于燕山早期闪长岩及潜火山岩中.矿体与潜火山岩岩体之间在空间上和成因上关系密切.闪长岩和潜火山岩既是矿体围岩,亦是成矿母岩.此外,二叠系安山岩可能亦为矿源层.成矿作用在低温、低压,大气降水为主的条件下形成.有利的矿源地层和火山机构是成矿的主要控制因素.
The middle-sized Guandi electrum deposit occurs in the early Yanshanian diorite and subvolcanic rocks. The ores are closely related to the subvolcanic rocks in both space and origin. The subvolcanic rocks are not only the wall rocks but also the parent rocks for the ores. Moreover, the Permian andesite is another ore-forming country rock. The metallogenesis is achieved under the conditions of low temperature, low pressure and atmospheric precipitation. The m…查看全部>>
