吉首市大坪方解石矿地质特征及成因探讨

Geological features and genesis of daping calcite in jishou-ping city

湘西地区有较多的方解石矿床分布,大坪方解石矿体(层)呈脉状产出,方解石以断裂裂隙填充方式富集,为地下热液型矿床。本文详细阐述了大坪方解石矿区地质特征、矿床地质特征、控矿因素,分析了矿床成因(中低温热液裂隙充填型),并对热液成因矿床的观点进行阐述,希望可作为本区或类似地区寻找同类型矿床研究和参考。

There are many calcite deposits in western hunan,and the dabing calcite ore body(layer)is produced in a vein.Calcite is enriched by fracture and fissure filling,which is an underground hydrothermal deposit.This paper expounds the ohtsubo calcite mining area geological characteristics,ore deposit geological features,ore-controlling factors,analyzes the genesis(fissure filling type of fluid(medium to low temperature),and elaborates the views on hydrothermal genesis of ore deposit,hope that can be used as or similar areas looking for the same type ore deposits in this area study and reference.
