摘要
根据 1∶5万永乐幅及平江幅自然重砂全分析鉴定结果的统计 ,结合区域地质矿产特征 ,论证了雷公山南坡重砂的矿物组合。反映了青白口系 (下江群番召组、清水江组、隆里组 )及南华系沉积环境的变迁 。
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.
