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。
