Title: Geological characteristics and genesis of the silver deposit at Xikeng in Yixian County, Southern Anhui Province
Abstract: This paper studies the deposit′s geological characteristics such as the shape of silver ore body,ore composition, texture and structure,ore forming physical and chemical condition ,existing forms of silver in the ore,and magmatism at the mine area.The stratous geochemistry of the mine area and far from the mine area is also studied. According to the study of the stratous geochemistry and geological characteristic of the deposit,the author thinks that it is a continuous process of thermal event of magmatism from thermal metamorphism of pro metallizing,tremolite diopside forming at early term to sulfidization at late term.The ore forming material comes from magmatic fluid.While acid magmatic fluid rises along zone of fracture in the mid stratum, the ore forming material fills up the fracture because of the reaction between the magmatic fluid and rock which is high active and rich incarbonate.
