摘要
本文介绍了一种新的成矿流体示踪法:N_2-Ar-He示踪体系,概述了其主要原理和分析方法,并以粤中长坑Au-Ag矿和粤东嵩溪Ag-Sb矿为例,进行了成矿流体N_2-Ar-He示踪体系研究,结果显示其成矿流体均主要来自建造水或沉积热卤水,为矿床成因研究提供了新的证据。
A new indicator of ore-forming fluids source, N2-Ar-He compositions in fluid inclusions, including its principle and analytical method, has been introduced. A case study has been taken on two Chinese ore deposits: the Changkeng Au-Ag deposit and the Songxi Ag-Sb deposit situated in Guangdong Province, South China. The results show that the ore-forming fluids in the two deposits are mainly composed of formation water or sedimentary hot brines, which provides new evidence for the genesis of the two deposits.
