Heavy mineral alanysis of surface sediments from the west-Pakistan and the adjacent continental shelf

Sediment samples from the southern West-Pakistan and the adjacent shelf have been studied for their heavy mineral contents and compositions. It is shown that the sediment load of the Indus river has influenced the sedimentation in the shelf areas south, southwest and in front of the Indus delta to a greater extent than in northerly direction. In the northern shelf region the smaller local rivers have dominated the marine sedimentation.

本研究针对巴基斯坦南部沿海及邻近陆架（shelf）的沉积物样品，开展了重矿物（heavy mineral）含量与组成特征的系统分析。研究结果显示，相较于北向区域，印度河输沙量对印度河三角洲以南、西南及三角洲前缘的陆架区域沉积过程的影响更为显著。而北部陆架区域的海洋沉积作用，则主要由小型地方性河流主导。
