| 摘 要： | 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。

| 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. |
