| 摘 要： | 本溪县杨家堡子金矿赋存于早古生代奥陶系马家沟组及寒武系凤山组内,矿体主要围岩为变质程度轻微的碎屑沉积岩及碳酸盐岩,矿体受断裂构造控制,金矿物及载金矿物——黄(褐)铁矿均呈稀疏浸染状分布,金成矿与燕山期二长花岗岩关系密切,具有"卡林型"金矿床地质特征。认为杨家堡子金矿是与早古生代寒武系、奥陶系地层、岩性、岩相(变质相)、断裂构造及燕山期岩浆活动有成因联系的金矿床,对矿体的矿物组合进行分析,初步确定矿化成因应属低温热液型金矿床。

GEOLOGICAL CHARACTERISTICS AND GENESIS ANALYSES OF THE YANGJIAPUZI GOLD MINE IN BENXI COUNTY,LIAONING PROVINCE |

| Abstract: | The Yangjiapuzi gold mine is hosted in the Majiagou group of Ordovician and the Fengshan group of Cambrian.Surrounding rock of ore body is clastic sedimentary rocks and carbonate rocks with slight metamorphic. Ore bodies are controlled by fracture structure, and gold mineral and gold-bearing minerals of yellow (brown) Iron were distributed sparsely disseminated. Gold mineralization is closely related with Yanshan adamellite and has geological characteristics of Carlin-type gold deposit. Studies suggest that Yangjiapuzi gold mine is genetically ralated to Cambrian, Ordovician strata, lithology, facies (metamorphic facies), faults and Yanshanian magmatism. This paper analyzed the mineral composition of the ore body, preliminary identifie the ore belong to low temperature hydrothermal type gold deposits. |
