摘要
Abstract
Mengxing lead-zinc deposit is a large-scale lead-zinc depoist in the Longling-Luxi polymetallic metallogenic belt of west Yunnan.The macroscopic researches of stratigraphic lithology,tectonics,alteration,and other geologic features were carried out through the collection of regional geological data,then the system confirmed the deposit's metallogenic tectonic environment,lamellar limestone,and its cleavage features.The ore body is located in the bottom of carbonate rock formations,it has the obvious stratabound characters.The features of lamellar limestone in the mining area shows the oxidation-reduction fluid properties of the lead-zinc mineral.Metallogenesis is controlled by regional syncline and longitudinal fracture in total,the rock stratum in the mining area becomes to layer-to-layer sliding surface and layer-to-layer crushing belt,cleavage banding affected by bedding compression,it provides an important migration pathway and ore accommodation space to mineralization.Overall,the deposit belongs to sedimentary-reformed lead-zinc deposit in general,its deep part might overlay concealed rock body mineralization,and it has huge prospecting potential.关键词
