扬子板块东南缘微细粒浸染型金矿床为低温热液矿床，成矿热液演化体系比较复杂．本文依据热液地球化学和矿床地质研究．首次将该类矿床的成矿热液划分为四个成矿热液演化体系：（１）大气降水成矿热液演化体系，溶液以大气降水为主，形成热泉型金矿；（２）石油卤水成矿热液演化体系，溶液来源于地层，以有机质参与成矿为特征，形成石油卤水热液型金矿；（３）盆地卤水（建造水）成矿热液演化体系，形成盆地卤水型金矿；（４）岩浆水－建造水成矿热液演化体系，成矿热液主要由岩浆水和地层中建造水构成，形成岩浆水－建造水热液型金矿．不同演化体系热液的Ｃ、Ｏ、Ｈ、Ｓ同位素和矿液成分均有明显的差异．
The fine grain disseminated gold deposits in the southeastern margin of the Yangtze block are low-temperature hydrothermal deposits, and the ore-forming hydrothermal evolution system is rather complicated. This article is based on hydrothermal geochemistry and deposit geology. For the first time, the ore-forming hydrothermal fluids of this type of deposit are divided into four ore-forming hydrothermal evolution systems: (1) atmospheric precipitation mineralization hydrothermal evolution system, the solution is dominated by atmospheric precipitation and hot springs type gold deposits are formed; (2) Petroleum brine mineralization hydrothermal evolution system, the solution from the strata, with organic matter involved in mineralization is characterized by the formation of petroleum brine hydrothermal gold mine; (3) basin brine (water) mineralization hydrothermal evolution system, the formation of basin brine Type gold deposit; (4) magmatic water-hydrothermal mineralization system for water mineralization; the ore-forming hydrothermal fluids are mainly composed of magmatic water and constructed water in the formation to form magmatic water-a hydrothermal gold deposit. The hydrothermal C, O, H, S isotopes and ore fluids of different evolution systems have obvious differences.
