西藏弄如日金矿南矿段最新勘探成果及意义
|
摘要
以补充详查的钻孔资料为基础,总结了弄如日金矿的最新勘探成果。结合最新勘探成果,弄如日金矿南矿段的下一步找矿方向应该围绕近南北向断裂、林布宗组红柱石角岩和中新世二长花岗斑岩的结合地带来进行,且沿矿体倾深方向存在稳定矿体的可能性非常大,应当作为下一步找矿勘探的重点。另外,在钻孔施工过程中应适当加密,以便更加准确地控制矿体产状及计算矿床储量。
Based on the drilling hole data with supplementary detailing survey,the latest prospecting achievements of the Nongruri gold deposit are summarized.According to the latest prospecting achievements,the next prospecting directions of the southern block should focus on the intersections of the approximate NS-trending fracture,the andalusite hornfels in bulinzong formation and the miocene monzonite granite-porphyry.It is highly impossible for the stable ore body existing along the inclination direction,which should be considered as the next key ore prospecting.In addition,more drilling holes should be arranged so as to control the occurrence of the ore body and calculate the reserves of the ore deposit more accurately.
