山东灵山沟金矿床的成矿特征及矿化富集规律

THE METALLOGENETIC CHARACTERISTICS AND REGULARITIES OF MINERALIZATION AND Au—ENRICHMENT AT LINGSHANGOU GOLD DEPOSIT,SHANDONG PROVINCE

摘要:

灵山沟金矿床位于著名的招莱金矿带中部,是该成矿带内兼具“玲珑式”、“焦家式”双重矿化特征的过渡型金矿的典型代表。本文重点阐述了该矿床的成矿多阶段性和矿化分带性特征,初步总结了矿化局部富集的一般规律及其在整个招莱地区的普遍性意义。

Abstract:

Lingshangou gold deposit is located in the middle of the famous Zhaolai gold belt. It has both "Linglong-type" and "Jiaojia-type" dual minerogenetic characteristics. Gold mineralization mainly occurred during hydrothermal process and can be classified into four ore-forming stages, viz. Ⅰ:Py-Q_2, Ⅱ: Q_2Py, Ⅲ: Q_2-Polymetallosulhides, Ⅳ: Q_2-Carbonates. Among them, Ⅱ and Ⅲ are major ones. the gold deposit has two zonation types, i. e. zoning of mineralization typs caused by the mechanical properties of orecon...
