【摘要】 <正> 本文所涉及的地理范围是从辽东沿岸向南到32°N,124°E以西的整个黄海海域。共分析了142个表层样品(0.25—0.063mm粒级)。采用重液分离(重液的比重为2.80)后的镜下鉴定的方法,然后计算出矿物的百分含量。在调查区内共发现有47种矿物成分,其中轻矿物的平均含量为97％,重矿物的平均含量仅3％。现分述如下:更多还原

【Abstract】 The results of our study show that there are a total of 47 minerals in the sediment samples analyzed. The area investigated may be divided into six mineral provinces and one sub-province on the basis of their heavy and light mineral assemblages: the Liaodong mineral province of hornblende and orthoclase, the Penglai-Haiyang mineral province of mica and chlorite, the Qingdao mineral province of epidote, the ancient Huanghe River estuary mineral province of mica and dolomite, the southeastern mineral province of hornblende, sta-urolite, kyanite and andalustite, the transitional mineral province, the Cape of Chengshan mineral subprovince of magnetite and ilmenite. The sediments of the Huanghai Sea are mainly derived from the Huanghe River and coastal region.更多还原
