利用南黄海222个沉积物样品的轻矿物鉴定资料,对南黄海的轻矿物百分含量分布进行了详细的划分,突出了极高值和低值含量的分布.划分出5个轻矿物组合分区:Ⅰ-南黄海北部矿物区,物质主要来源于黄河;Ⅱ-南黄海中部矿物区,物质多来源于黄河,一部分来源于长江;Ⅲ-混合矿物区,物质来源受黄河、长江的双重影响;Ⅳ-长江口东部矿物区,物质主要来源于长江;Ⅴ-南黄海南部矿物区、物质来源可能受残留沉积影响,且受现代长江的影响较大,区分出5个轻矿物分区的优势矿物组合以及特征矿物.
Using the light mineral identification data of 222 sediment samples in the South Yellow Sea, the distribution of light minerals in South Yellow Sea is divided in detail, highlighting the distribution of extremely high and low values, and five light mineral assemblages : Ⅰ- The northern part of the southern Yellow Sea mineral area, the material mainly comes from the Yellow River; Ⅱ- Central South Yellow Sea mineral area, most of the material comes from the Yellow River and partly from the Yangtze River; Ⅲ-mixed mineral area, the source of material is doubled by the Yellow River and the Yangtze River; Ⅳ- The minerals in the eastern part of the Yangtze Estuary are mainly derived from the Yangtze River; Ⅴ- The mineral sources in the southern part of the southern Yellow Sea may be affected by residual sediments, and are greatly influenced by the modern Yangtze River. Five dominant mineral assemblages are distinguished As well as characteristic minerals.
