| 摘 要： | 在五台山绿岩带中的东腰庄金矿 ,发现部分容矿绢云母石英 (片 )岩实为变质基性岩 (变质辉绿岩—辉绿玢岩或安山玢岩 )岩床在五台期构造作用下发生强烈的剪切变形和变质热液蚀变的产物。说明以绢云母石英 (片 )岩作为容矿围岩的东腰庄金矿 ,确有部分为变质基性岩在含金剪切带中发生热液蚀变的后生成因。矿床的形成和矿质的富集受剪切变形机制控制明显 ,并与区域构造背景有着密切的关系

A Simple Analysis of Metallogenic Geologic Features and Ore-Control Factors of Dongyaozhuang Gold Deposite in Wutaishan Greenstone Belt |
| |
| Abstract: | Dongyaozhuang gold deposits is in Wutaishan greenstone belt. The partial host rocks has been found sericite guartz schists are the products of metamorphic basic rocks(metadiabas, metadiabas porphyrite, metaandesite porphyrite)with strongle shear deformation and meta hydrothermal alteraion during the structure process of Wutai period, It suggests that those parts of Dongyaozhung golt deposits of holding ore by means of sericite quartz schists partly havre an epigenetic origin of metamorphic hydrothermal alteration in the shear zone. The formation of the deposits and assemblage of the ore materials are distinctly controlled by shear deformation mechanism and the regional structure setting. |
