Water-rock interaction demonstrates that, a gold-boring formation , i. e., a set of light metamorphic clastic gritstone, sandy slate, and tuffaceous slate in Wuqiang Runnel Formation, Ban Stream Group, act as the source of gold deposits in South-West Hunan. The gold is originally derived from volcanic eruption materials in Wuling-Xuefeng period; for the typical single gold deposit such as Mobin, which is short of sulphide, chlorine is very important in the metallogenic process; sulphur and chlorine perform as the major negative ions to form complex ions with Au throughout the gold activation and migration movement. The complex ion of chlorine and gold may keep stable in a wide range of temperature; the physical-chemical conditions in typical geothermal fluid system are of deciding significance for gold activation, migration and precipitation.

特定体系的水岩实验证实了漠滨及整个湘西南金矿的成矿元素Au和伴生元素主要源于赋矿围岩-板溪群五强溪组的一套浅变质碎屑砂岩、砂质板岩和凝灰质板岩;首次突破传统认识,证明氯在中低温热液体系中能与Au形成稳定络合物的形式进行运移,因此氯在本区Au成矿过程中起着相当重要的作用;成矿热液流体中Au主要以金硫、金氯络合物形式在溶液中迁移,阴离子∑S、Cl〓对金的活化、迁移及沉淀起主导作用,Au的伴生元素As、Sb在热液体系中与Au形成金锑、金砷络合物有利于金的进一步活化、迁移及沉淀;中低温热液流体成矿过程中,体系的物理化学参数对Au的活化、迁移及沉淀富集起决定性作用。
