本文阐述了右江裂谷区微细粒浸染型金矿床控矿层位三叠系百蓬组泥质粉砂岩及砂质泥岩的粒度，比表面、孔隙度及孔隙类型和渗透率等物性特征，讨论了与其成矿流体的循回、水岩反应及其有效浸取围岩矿物质的关系。在此基础上提出了成矿流体和成矿物质主要来自于地层；由于热液向低势能方向迁移，造成断裂发育的盆地边缘区和水下隆起周围的环状断裂带为金矿床沉淀的场所。并通过形成金矿所需热液量的估算得出，该区金矿床的形成，是由于热流体（发生在矿区及其外围）的深循环作用或者是流体多次循回叠加作用。
This paper describes the particle size, specific surface area, porosity, pore type and permeability of the Triassic Baipeng formation mudstone in the Youjiang layer of the Youjiang fine-grained disseminated gold deposit in the Youjiang Rift Valley. It is related to the circulation of ore-forming fluid, water-rock reaction and its effective leaching of surrounding rock minerals. On this basis, it is proposed that the ore-forming fluids and ore-forming materials are mainly from the strata. Because the migration of hydrothermal fluids to the low potential energy, the marginal zone of the basin and the ring-shaped fault zone around the submarine uplift cause the deposition of gold deposits . And through the formation of the required amount of hydrothermal gold, it is concluded that the formation of gold deposits in this area is due to the deep circulation of the hot fluid (occurring in the mining area and its periphery) or the multiple superimposition of fluids.
