摘要
用岩石磁化率各向异性分析方法研究了庐山东南麓下岸角剖面地层的古流向.结果表明:古流向为N、NW流向S、SE、SW,说明这套地层的物源为庐山.地层层理产状及重矿物组合也证明,这套地层为源于庐山的中小型河流冲积而成。
Estimate of the palaeocurrent was studied by using the anisotropy of rocks magnetic susceptibility(AMS) measurements at Xiaanjiao section in southeast Lushan areas.The results of the AMS measurements shows that the palaeocurrent of the stratum in Xiaanjiao section was from N、NW to S、SW、SE.The results points those rocks were from Lushan mountain,not from Ganjiang river.The results were proved by the composition of the heavy mineral and the inclinations of the bedding.
