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。

摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题：①铀成矿既可形成于浅源浅成低温条件，也可形成于深源深成高温或深源浅成中低温条件，在强调深源时，不是简单地认为是幔源就可以了，还必须强调壳幔作用的地质过程；②打破人为的&类型&划分，加强&铀成矿系统&的研究，更好地指导找矿；③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题，注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿；④火山盆地基底对铀成矿的作用主要是提供铀源，将基底对铀成矿的影响从感性认识推向理性认识，有效地指导找矿；⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论，它不仅仅是一个理论问题，而且有助于铀成矿预测；⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造，是华东火山岩型铀矿找矿的新领域。

Combined with the regional data the research indicates that (1) the Tianmenshan main body formed in the Middle Jurassic Epoch, whereas the minor body was the further differentiated and evolutive product of the main body;(2) in the Chongyi-Dayu-Shangyou ore concentrated area, the west of Gannan area, the diagenetic age and metallogenic age are basically concordant, and the mineralization concentrated during 150~155 Ma;(3) from the middle-plutonic granite intrusion to the hypabyssal granite-porphyry vein, the magmatic activities experienced only 1~5Ma, indicating there was the concentrated period of mineralization.

结合区域资料，研究表明：①天门山岩体的主体形成于中侏罗世，补体是主体进一步分异演化的产物；②在赣南西部的崇余犹矿集区内成岩与成矿的年龄基本上是协调一致的，成矿集中期为150～155 Ma；③岩浆活动由中深成相花岗岩侵入体演化到浅成相花岗斑岩脉仅相差1～5Ma，表明存在成矿集中期。
