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.
