【摘要】：通過(guò)采用兩種不同的粒度預(yù)處理方案,對(duì)南海南部表層沉積物進(jìn)行了粒度分析,探討了生物硅對(duì)南海南部表層沉積物粒度結(jié)果的影響。結(jié)果表明,生物硅無(wú)論是對(duì)粒度組分、粒度參數(shù),還是對(duì)沉積物類型都有顯著的影響。同時(shí),結(jié)合顯微鏡鏡下涂片鑒定的硅質(zhì)生物碎屑含量,認(rèn)為要獲取有效的南沙陸坡區(qū)的陸源沉積物的粒度分布特征需去除掉生物硅。通過(guò)對(duì)比發(fā)現(xiàn)南海南部表層沉積物生物硅的主要粒級(jí)分布范圍為8~90μm。
[Abstract]:The particle size of surface sediments in the south of the South China Sea was analyzed by using two different particle size pretreatment schemes, and the effect of biological silicon on the grain size of surface sediments in the south of the South China Sea was discussed. The results show that biogenic silicon has a significant effect on particle size composition, particle size parameters and sediment types. At the same time, in combination with the siliceous bioclastic content identified by microscopical smear, it is considered that the removal of biological silicon is necessary to obtain the grain size distribution characteristics of land-based sediments in the Nansha continental slope area. It is found that the main particle size distribution range of biogenic silicon in the surface sediments of the southern South China Sea is 890 渭 m.
