连平县忠信南部地区地质特征及矿产成因分析

Geological characteristics and mineral genesis analysis of Zhongxin south area in Lianping County

根据区域地质资料和调查成果,从地层、岩浆岩和控矿构造阐述成矿地质条件,分析各矿区矿体特征和矿石质量,探讨研究区成矿物质来源和成因。矿床类型为中酸性岩体侵入形成的接触带矽卡岩型,矿体与围岩没有明显界线,属渐变过渡型。

According to the regional geological data and survey results,the metallogenic geological conditions are expounded from the strata,magmatic rocks and ore controlling structures,the ore body characteristics and ore quality of each mining area are analyzed,and the source and genesis of ore-forming materials in the study area are discussed.The deposit type is skarn type of contact zone formed by the intrusion of intermediate acid rock mass.There is no obvious boundary between the ore body and the surrounding rock,which belongs to the gradual transition type.
