植物硅酸体（以下简称硅酸体）在海洋沉积学中的应用始于Smithson对Leigwy湾海底沉积物的分析。后来他又对日本九州的Ariake湾浅海沉积物做了硅酸体分析。Dumitrica在1973年对地中海沉积岩心做了硅酸体分析,深海钻探第47航次（1979）、第54航次（1982）都做了钻孔岩心的硅酸体分析,据钻孔岩心硅酸体分析结果,推测了中新世～上新世的古风向和北非的古植被。我国从1989年开始对海岸带堆积和近浅海沉积做了一些硅酸体研究工作,冲绳海槽C1孔岩心硅酸体分析是我国第一次在半深海做硅酸体分析工作,该岩心位于冲绳海槽中段水深1600m处,位置为126°10’E,27°02′N,岩心长6.25m,岩性以泥质粉砂和粉砂质泥为主。
The application of plant silicate (hereinafter referred to as silicate) in marine sedimentology began with Smithson’s analysis of the seabed sediments in Leigwy Bay. He later performed a silicate analysis of the shallow sea sediments in the Ariake Bay, Kyushu, Japan. Dumitrica performed a silicate analysis of the Mediterranean sedimentary core in 1973, and deep sea drilling on the 47th (1979) and 54th (1982) boreholes performed silicate analysis of boreholes. According to the borehole core silicate analysis As a result, the Miocene-Pliocene paleoclimate and the ancient North African vegetation were inferred. Since 1989, some researches on silicic acid have been done in coastal accumulation and near-shallow-sea sedimentation in China. The analysis of silicate in C1 hole in Okinawa Trough was the first time that China did silicate analysis in semi-deep sea, At the depth of 1600 m in the middle part of the Okinawa Trough, the location is 126 ° 10’E and 27 ° 02’N, with a core length of 6.25 m. The lithology is dominated by muddy silt and silty mud.
