微细粒浸染型金矿，又叫卡林型金矿床，是世界重要金矿类型之一。该类矿床普遍含有一套中、低温的矿物共生组合及围岩蚀变，赋矿地层有机碳含量高。本研究以我国著名微细粒浸染型金矿床──四川省松潘县东北寨金矿为例，对该类矿床进行了实验和地球化学热力学研究，获得以下认 Micro-disseminated gold, also known as Carlin-type gold deposits, is one of the world’s major gold types. Such deposits generally contain a set of medium and low temperature mineral assemblages and wall rock alteration, and the ore-bearing strata have high organic carbon content. Taking the gold deposit in Dongbeizhai, Songpan County, Sichuan Province as a well-known micro-disseminated gold deposit in our country as an example, this study was carried out on the thermodynamics and geochemistry of this type of deposit.
