摘要
对川西北壤塘西康群浊积砂岩的常量元素、稀土元素及微量元素的综合研究表明 ,其地球化学特征与大陆岛弧和活动大陆边缘沉积物相同。综合其它地质资料可以认为 ,本区浊积岩的物源区为康滇古陆。
A comprehensive investigation into the major elements, rare-earth elements and trace elements of turbidites of the Xikang Group in the Rangtang area, Sichuan Province shows that the geochemical characteristics of the sandstone are similar to those of sediments of continental island-arc and active continental margin. Based on the geological data, it is thought that the Kangdian oldland is the source of turbidites.
