焦家金矿属于蚀变岩型金矿,围岩蚀变发育,是我国储量最大的金矿床之一。该文对蚀变带中的钾长石的赋存状态、化学成分进行了分析研究,并与未蚀变的玲珑岩体中的钾长石进行对比。认为焦家金矿床主要存在三种成因类型的钾长石,即原生钾长石(岩浆成因)、高温热液钾长石、低温热液钾长石。结合前人的研究成果,探讨了热液钾长石的形成与成矿意义。
焦傢金礦屬于蝕變巖型金礦,圍巖蝕變髮育,是我國儲量最大的金礦床之一。該文對蝕變帶中的鉀長石的賦存狀態、化學成分進行瞭分析研究,併與未蝕變的玲瓏巖體中的鉀長石進行對比。認為焦傢金礦床主要存在三種成因類型的鉀長石,即原生鉀長石(巖漿成因)、高溫熱液鉀長石、低溫熱液鉀長石。結閤前人的研究成果,探討瞭熱液鉀長石的形成與成礦意義。

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.
