| Abstract: | According to the study topography, sedimentary, granularity and form of gold and characteristic features of the orebed. Authors think that the shuanglong gold placer is a terrace-type gold placer, which is an outwash accumulation due to the glacial and chemical actions in the mid-late pleistocene and the early Holocene epochs. |
