胶东焦家金矿床钾长石成因及成矿意义
摘要
Abstract
Jiaojia gold deposit belongs to altered rock type gold deposit,which has extensive wall rock al-teration.It is one of the biggest gold deposit in reserves.Occurrence and chemical composition of the K feldspar in the alteration rock have been analyzed and studied,and compared with the K feldspar in the non alterated Linglong rock bodies.Three genetic types of K feldspar occurred in Jiaojia gold deposit, including native K feldspar (magmatic origin),hydrothermal K feldspar of high temperature and hydro-thermal K feldspar of low temperature.Finally,combining with previous research,the formation and its mineralization significance of the hydrothermal K feldspar have been discussed.关键词
