The profile distributions of silicate, phosphate and nitrate suggest that the organic material decomposition in area is mainly through nitrification during early diagenesis. Based on benthic fluxes of nutrients calculated using Fick's first law, benthic fluxes of silicate, phosphate and nitrate are -886.45~42.62 mol/(m^2d),-3.04~5.83 mol/(m^2d) and -189.43~21.05 mol-(m^2d), respectively, and perhaps silicate and nitrate are one of the major sources of nutrients for bottom water. Our results also reveal temporal and spatial variations of benthic fluxes for silicate, phosphate and nitrate, which may be related to sedimentation environment changes caused by global climatologic change.
在水-沉积物介面附近矽酸盐、磷酸盐和硝酸盐都存在著极陡的浓度梯度,Fick扩散定理的计算结果表明,研究区内矽酸盐、磷酸盐和硝酸盐的海底扩散通量分别为-886.45~42.62mol/、-3.04~5.83mol/和-189.43~21.05mol/,且矽酸盐和硝酸盐主要是从沉积物向底层水体扩散,是底层水体营养盐的来源之一;研究区内矽酸盐、磷酸盐和硝酸盐的海底扩散通量存在著一定的时间和空间变化,这可能与因全球气候变化而导致的沉积环境的改变有关。

This paper also shows the distribution of the fluorine in sediments of the area is mainly controlled by the chemical composition of the material from the surrounding islands, and the element seems to be incorporated by the hornblende at the most extent, thus the correlation between the element and the hornblende amount in the sediments can be expressed statistically as following: F=217+lnVh.
研究结果表明,测区沉积物中氟含量分布主要受周围岛屿风化基岩的化学成分制约;沉积物中主要含氟矿物:萤石/磷灰石、黄玉、黑云母等含量极低,氟在沉积物中赋存的矿物相主要与角闪石[AX_2Y_5Z_8O_(22)_2]有关。氟含量与碎屑矿物中角闪石的体积比间的关系式可大致表示为:氟含量=217+361nV_H;间隙水中的低氟主要由测区化学风化不发育及氟的钙盐沉积所致。

Among them, the black rings puts in order salt crust sand content to increase, but the white rings puts in order by the silt and the clay primarily. The light and shade interaction annulus of salt crust granulometric composition difference are showed that the saline lake passed by evolutionary process, because of the climate and temperature changes in turns, which causing the saline lake deposit ingredients have regular change results.
