利用 1995年中韩合作项目在黄海东部海域获得的 YSDP10 2钻孔岩心 ,选取了 2 8个样品进行了矿物学的分析与测试 ,共发现矿物 2 4种 ,其中重矿物 2 0种 ,组合为绿泥石、云母、绿帘石、角闪石、石榴子石。结果显示重矿物组合及物质来源比较稳定 ,主要是冰消期以来海侵过程对陆架上早期沉积物的改造 ,其次是各种海洋动力对陆架基岩的侵蚀所形成的沉积物 ,在垂向上可以分成 3个矿物段 ,这 3个矿物段与沉积环境密切相关
Using the YSDP10 2 drilling core obtained from the Sino-ROK cooperation project in the eastern Yellow Sea in 1995, 28 samples were selected for mineralogical analysis and testing. Twenty-four kinds of minerals were found, of which 20 were heavy minerals with a combination of Chlorite, mica, epidote, amphibole, garnet. The results show that the heavy mineral assemblages and material sources are relatively stable, mainly due to the transgression of the early sediments on the shelf by the transgression process since the expiration of the ice, followed by the sediments formed by erosion of the various marine motive forces on the continental shelf rocks. It can be divided into three mineral segments, which are closely related to sedimentary environment
