摘 要： 对东海沿岸陆架CJ08-630、CJ08-923、CJ08-1185三个柱状岩心56个重矿物样品63-125μm粒级重矿物的研究表明,重矿物种类有56种,最高含量可达53.1%;平均含量较低,为8.5%,;矿物组成以闪石类、帘石类、辉石类、片状矿物、自生黄铁矿及金属矿物磁铁矿、褐铁矿等等为主。重矿物来源复杂多样,包括陆源、火山、自生等各种来源的矿物。其中沿岸河流输入物是主要陆源矿物来源;此外还有沿岸和岛屿等的剥蚀物、冲刷物。沉积环境是影响重矿物分布的主要因素。
Abstract: On the coast of the East China Sea continental shelf CJ08-630, CJ08-923, CJ08-1185 three cylindrical core 56 heavy mineral samples 63 ~ 125 μ m particle heavy mineral studies show: Heavy minerals, 56 types of species, the highest content of up to 53.1 percent; average levels of low, at 8.5%. To amphibole mineral composition category, curtain-type, stone-like, flaky mineral, pyrite and self-metallic mineral magnetite, limonite, and so on the main. Heavy mineral sources of complex and varied, including land-based sources, volcanoes, since a variety of sources, such as the Health and minerals. Which enter rivers along the coast of the main sources of land-based sources of minerals; There is also the coast and islands of the erosion, erosion of. Sedimentary environment is the impact of heavy mineral distribution of the main factors.
