绍兴花岗闪长岩小岩株侵入在元古宙双溪坞群的细碧-石英角斑岩火山岩系之中。绍兴-江山深大断裂控制了矿田和岩株的构造。岩株可划分三个相带。本文详细研究了花岗闪长岩的构造以及三个相带的岩石成分。根据岩石化学和微量元素化学分析、簇群分析及同位素值的研究等证实,此侵入岩体和它的围岩主要来源于上地幔岩浆源。我们在此岩株的断裂和构造破碎带及其与火山岩的接触带中,圈定了四个有远景的金-银矿化带。
Shaoxing granodiorite small intrusive rocks in the Proterozoic Shuangxiwu group spit Bi - quartz horn porphyry volcanic rocks. Shaoxing-Jiangshan deep fault controlled the structure of the ore field and the rock mass. Rock strain can be divided into three phase belt. This paper studies in detail the structure of granodiorite and the rock composition of three facies belts. Based on petrochemical and trace element chemical analysis, cluster analysis and isotopic study, it is confirmed that the intrusive rock mass and its surrounding rock mainly come from the upper mantle magma source. We identified four prospective gold-silver mineralized zones in the fault and structural fractures of this rock mass and their contact with volcanic rocks.
