| Abstract: | Placer minerals composition in the southern slope of Mt Leigongshan is demonstrated by the analysis on 1:50,000 scale natural placer of Yongle size and Pingjiang size in combination with regional geology mineral features, the Qingbaikou system (e.g. the Fanshao formation of the Xiajiang group, the Qingshuijiang formation, and the longli formation) and the Nanhua system are expressed to the environment-sedimented variance, its terrigenous debris originated from paleo-yangtze continental core. |
