江西省万安县大坪地区成矿地质特征及找矿方向

Metallogenic geological characteristics and prospecting direction of Daping area,Wan'an county,Jiangxi province

通过对大坪矿区区域地质特征、矿体地质特征及矿石质量等研究表明,矿床成因以燕山晚期地层分异为主导,叠加次生风化作用共同制约的,研究区内断裂构造为控矿构造,构造形态、规模、产状对矿脉的变化起到决定性作用。文章所提出的找矿方向对江西省万安县大坪地区的矿产资源勘查工作具有一定的意义。

The study on the regional geological characteristics,ore body geological characteristics and ore quality of Daping mining area shows that the genesis of the deposit is dominated by the stratigraphic differentiation in the late Yanshan period and restricted by the superposition of secondary weathering.The fault structure in the study area is the ore controlling structure,and the structural shape,scale and occurrence play a decisive role in the change of the ore vein.The prospecting direction proposed in this paper is of certain significance to the mineral resources exploration in Daping area,Wan'an County,Jiangxi Province.
