归来庄金矿床中金矿物与载金矿物的标型意义

TYPOMORPHIC SIGNIFICANCE OF GOLD MINERALS AND GOLD CARRYING MINERALS IN THE GUILAI-ZHUANG GOLD DEPOSIT IN PINGYI,SHANDONG

摘要:

归来庄金矿金矿物主要为自然金、碲铜金矿和银金矿，多呈角粒状产出，粒间金较常见，属细粒—微细粒金。载金矿物以脉石英、黄铁矿、褐铁矿及方解石为主。二者标型特征表明：该金矿属浅成中低温热液型金矿床，泰山群变质岩系为其主要矿源层，并且有来自地球深部的金质参与成矿。文中提出了与金矿化相关的元素变化特征和宏观找矿标志。

Abstract:

In the Guilaizhuang gold deposit native gold,kostovite and electrum are the main gold minerals which Commonly occur as fine to ting angular grains in the interstices of other minerals. Vein guartz,pyrite,limonite and calcite are the dominant gold-carrying minerals The typomorphic characteristics of these minerals have shown that the Guilaizhuang gold deposit belongs to the shallow-level meso-to epithermal deposit. The Taishan group metamorphic rocks are the main source bed of gold while some gold has come f...
