After thermodynamic studies on the former two typical fine disseminated gold deposits, the following facts are found: both existent and transferring form of gold in mineralizing hydrothermal solution are predominated by Au 〓 and AuH〓SiO〓; the contribution of AuCl〓〓 is negligible to mineralization; and those contribution of gold bearing complexes including Au with As-S and Sb-S are much less than that of Au 〓 and AuH〓SiO〓, organic complex take effect in some degree during the relatively low temperature activating period of gold.

对以上两个典型微细浸染型金矿床的热力学研究，发现成矿热液中金的存在和迁移形式均以Au〓和AuH〓SiO〓为主，AuCl〓对金迁移成矿的贡献微不足道，金砷硫或金锑硫等复合配合物对金成矿的作用远不及Au〓和AuH〓SiO〓，有机配合物在温度较低的金的活化期有一定作用。

The activated or leached process and their influence elements are studied by 1DREACT software package of coupled mass/heat transfer and chemical reaction dynamics of water-rock interaction, according to the geological and geochemical characters of fine disseminated gold deposits.(1) Water-rock reaction time is not the important influence element of activating gold;(2) At first, activating capability of hydrothermal solution increases with the increasing of total sulfur activity; after lga〓≥-4, the content of activated gold in solution is mainly related to original content of gold in wall rock, and does not visibly dependent on total sulfur activity.(3) It is a complicated nonlinear process of influence of activating gold capacity of hydrothermal solution with the change of temperature, in general, 220 ℃ is most favorable to gold activation.(4) The influence of oxygen fugacity on gold activation has a multiple functions coupling nonlinear effect, in general, Igfo〓=-41 is most favorable to gold activation.(5) Solubility of gold in fluid decreases with the increasing of velocity of flow, the product of velocity and aurous solubility reaches maximum when velocity is 0.2～0.5m〓m〓. yr〓, i. e. this scope of velocity is most favorable to gold activation.

利用1DREACT水-岩相互作用反应-输运耦合动力学软件包，根据微细浸染型金矿床地质地球化学特征，计算机模拟研究了金的活化、浸取过程及其影响因素，发现：(1)金活化过程中水-岩反应时间不是其主要制约因素；(2)热液对金的活化能力开始随总硫活度的增高而增高，当lg a〓≥-4后，热液中活化金的含量将主要与围岩中金的初始丰度有关，而对总硫活度无明显依赖关系；(3)温度对热液浸金能力的影响是一个复杂的非线性过程，总体而言，220℃最有利于金的活化；(4)氧逸度对金活化的影响呈现出一种多因素叠加的非线性效应，总体而言，lgfo〓＝-41最有利于金的活化与浸取；(5)流体中金的浓度随流体流速的加快而降低，流速与金浓度的乘积在流速为0.2～0.5m〓m〓。yr〓时达到极大，即0.2～0.5m〓m〓。yr〓的流速范围最有利于本类矿床的金的活化。
