| Abstract: | Jinya gold deposits lies in formation of Middle Triassic Epoch in Northwest Guangxi and is one of typical micrograined dissminated gold deposits in Yunnan Guizhou Guangxi basin.The problem of gold source was extended over in studying the deposits.In this paper it is considered that the gold of Jinya gold deposits came from turbidite depositional basin of Middle Triassic Epoch by analyzing source of sedimentary material in depositional basin of Middle Triassic Epoch,comparing geochemical fields of source area and sedimentary area and studying characteristic of concentration and dispersion in sedimentation and lithogenesis. |
