摘要
本文通过对双龙砂金砂床的地貌、沉积物、金的粒度及形态、矿床产出特征的研究，认为该矿床是在中晚更新世及全新世初期的冰川（水）的作用及化学作用下而形成的冰水堆积－阶地型砂金矿床。
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.
