摘要
系统的常量元素、微量元素和稀土元素地球化学分析表明,皖南下震旦统雷公坞组碎屑岩,属弧后盆地沉积。以井潭组为代表的岛弧钙碱性火山岩区是其物源区。
A detailed geochemical analysis of major,trace and rare earth elements suggests that clastic rocks of Leigongwu Formation,Lower Sinian in southern Anhui derived from calc-alkaline volcanic are represented by JingtanFormation and deposited in a backarc basin.
