摘要
鲁西地区主要有两种金矿类型:火山热液型和绿岩带型。火山热液型金矿成矿物质来源丰富、成矿热动力强,形成了一系列大中型金矿床;绿岩带型金矿床,在成矿物质来源、成矿热动力及赋矿构造空间等方面存在先天不足,只能形成小型金矿或矿(化)点。鲁西地区主要的找矿方向为寻找与燕山期侵入杂岩体有关的火山热液型金矿床。
There are two main types of gold in western Shandong province： volcano hydrothermal type and greenstone belt. volcanic hydrothermal gold metallogenic is rich of source material, with a powerful thermokinetic for forming deposits and formed a series of large and medium-sized gold deposits. But the source material, the thermokinetic for forming deposits and the space of the mineralization structure and so all about green belt gold deposits have a congenital deficient, so it can only form small gold or mining points. In summary, the ore-searching direction in western Shandong province is mainly the complex body at Yanshan Period of the volcanic hydrothermal type gold deposits.
