摘　　要：山东省平邑县铜石地区是鲁西最重要的金矿产地,继归来庄大型金矿床发现之后,又相继发现了卓家庄特富金矿床及磨坊沟、梨方沟、贺山庄等具层控特征的金矿床,构成了铜石金矿田。这些金矿床的形成与铜石地区中生代多期次岩浆活动或隐爆作用密切相关,分布于岩体边部的隐爆-侵入角砾岩是金矿床的载体,成为寻找隐爆-侵入角砾岩型金矿的重要标志。Tongshi area in Pingyi county of Shandong province is the most important gold producing area in western Shandong. After the discovery of large scale of Guilaizhuang gold deposit, special--rich gold deposit of Zhuojiazhuang and some gold deposits with strata--controlling characteristics have found as well, such as Mofanggou gold deposit, Lifanggou gold deposit and Heshanzhuang gold deposit, etc. The formation of these gold deposits has close relation with Mesozoic multi--period magmatic activity and cryto--explosive function. Crypto--explosive and intrusive breccia distributed in the edges of rocks are carrier of gold deposits. They are important symbols for prospecting crypto--explosive and intrusive breccia type gold deposits.
