摘要
以老虎崖金矿床为研究对象,在充分野外地质勘查和前人工作的基础上,通过对历年来老虎崖一带勘查成果总结分析,认为老虎崖金矿矿床产出于东西向构造角砾岩或挤压片理化带中,矿体主要受背斜构造的灰岩与板岩的虚脱剥离空间控制,次要受背斜近轴部断裂控制,为一典型构造蚀变岩型金矿床,具较好找矿潜力。
This paper tiger cliff gold deposit as the research object, based on the field geological survey and previous work, through the analysis of the results of investigation on years of tiger cliff area, that tiger cliff gold deposit occurred in tectonic breccia or extrusion schistositilization, collapse stripping the main orebody by limestone and space the slate anticline con- trolled by anticline axis control in secondary fracture, altered rock type gold deposit is a typical tectonic erosion, with good prospecting potential.
