摘要:
通过对青海滩间山金矿花岗质岩石的岩石化学、稀土元素和铅同位素研究,证明了和金矿有关的花岗质 岩浆源于加里东期基性超基性岩的部分熔融或同源玄武岩分离结晶。岩浆中富金属硫化物的热液以及岩浆自 身的热能,为地层和岩浆中金元素的活化和运移提供了能量和载体,对金起着捕获和富集的作用,有利于金矿床 的形成。
Abstract:
Mylonite schist and granite are the main wall rocks of Tanjianshan gold deposit in Qinghai Province, and granitic rocks play an important role in the formation of gold deposit. Petrochemistry, REE and Pb isotope prove that the granitic magma comes from partial melting of Caledonian basic-ultrabasic rocks or crystallization of congenetic basaltic magma. The metal-sulfide-enriched hydrothermal fluid and thermal power of the granitic magma provide energy and carrier for the activation and movement of gold element, which capture and accumulate gold element, and is available to form gold deposit.
