Geological characteristics and genetic analysis of the Pinghe lead-zinc silver deposit in Tianwei mining area,Yizhang County,Hunan Province
This article introduces the overview of lead zinc silver deposits,including their stratigraphy,geological structure,magmatic rock and surrounding rock alteration,deposit characteristics,and ore body characteristics.Subsequently,the article analyzed factors such as ore-forming temperature,ore-forming fluid sources,ore-forming material sources,and ore-forming age.Through analysis,it can be concluded that the ore deposits are mainly distributed in limestone,shale,and sandstone,with high ore-forming temperatures.The ore-forming fluids mostly come from underground hot water,and the ore-forming materials mostly come from surrounding rocks and deep crustal materials.In addition,geological structure and alteration of magmatic rocks and surrounding rocks are also important factors in the formation of mineral deposits.The above conclusions are of great significance for understanding the formation mechanism of lead zinc silver deposits and guiding mineral exploration and mining.
