FORMATION OF CARBONATE IN THE SURFACE SEDIMENTS IN THE NORTHERN PART OF THE EAST CHINA SEA

Zhu Erqin Wang Qi Li Jianhua Xia Mingjie Cheng Qing ( Shandong College of Oceanography, Qingdao )  
There exists abundant carbonate in the surface sediments of the East China Sea. Its maximum content accounts for 51.2% of the whole weight of the samples or 70% of the whole volume. This article deals with some problems about carbonate, such as the variation of contents in the four parts(bulk sample,coarse-median-sand fraction, fine-sand one and silt-mud one), the distributive pattern,the mineral and biological form and the principal factors affecting its formation. In this region the continental shelf edge is an area with high carbonate content (30-50%).The other parts of the shelf are median ( 5-15%) in content; the areas with low content ( 5 % ) are distributed very sparsely. The carbonate has very high percentage ( 40.65% ) in the coarse-median-sand fraction which contributes a low amount to the bulk samples; and the other two fractions have the same mean content of carbonate as that ( 12.24% ) in the bulk samples. The carbonate in the region occurs mainly in the form of biogenic debris. We have made multiple cluster analyses of the quantitative statistics on the amount of the fossil fragments in 14 categories ( the total amount of foraminiferan, benthonic foram, planktonic foram, Echinoidea, Ophiuroid, Gasteopoda, Pteropoda, Lamelli-branchiata, Scaphopoda, Ostracoda, Anthozoa, Bryozoa, and Diatom ) of 7 phyla in the surface sediemnts ( coarse-fine-sand fraction ) .From the data we can see that there obviously exist four bioclast areas in the northern part of the East China Sea: 1 . Planktonic bioclast area. It is characterized by the planktonic foram and pteropoda in this region, and the coral and Bryozoa occupy a minor part. Nanno-fossil (Gephyrocapsa oceanica and Emiliania huxleyi are the dominant species) occurs only in the silt-mud fraction. Low-Mg calcite is the major mineral in foram, but high-Mg calcite. also constitutes a few genera. The fraction rich in biogenic debris of nannoplankton, also has a dominant composition of low Mg calcite. This area is characterized by high sedimentation rate of biogenic carbonate. 2 . Foram area. Foram debris accounts for 91.29% in the biogenic assemblage. This area occupies an extensive part of the intermediate shelf in which the eastern part is dominanted with the planktonic and has an significant sedimentation rate; but the other parts are characterized by the benthonic and a weak accumulation of modern carbonate. 3 . Mollusca area. This bioclast assemblage is restricted in the fossil delta of the Changjiang River. The total content of biogenic debris in the sediments is low. It is obvious that the accumulation of modern carbonate is quite weak. 4 . Nearshore bioclast area. It covers a narrow zone along the nearshore. Non-biological calcium carbonate consists of low-Mg calcite and occurs in the form of calcareous concretions, which generated in the fresh water on the land, and authigenic calcite crust crystallized in modern sea-botto'm. The concretions are distributed mainly in the fossil delta of the Changjiang River. The most important factor affecting modern biogenic sedimentation in the East China Sea is the warm Kuroshio Current, which controls the species of organism and the range and strength of biogenic sedimentation.
