Based on the quantitative studies of siliceous microorganisms and terrestrial detritus in 12 surface sediment samples , which were recovered by the first chinese national arctic expedition team , in the bering sea , it goes without saying that diatom abundance is dominant within the microorganisms which consists of diatoms , radiolarians and sponge spicules 摘要中國首次北極科學考察在白令海?取了12個表層沉積物樣品,其中對矽質生物和陸源碎屑的詳細研究發現,它們主要由矽藻、放射蟲和海綿骨針組成。

The coqen basin in xizang lies between the bangong - nujiang suture zone and yarlung zangbo suture zone , and once extended northwards and southwards , respectively centred by the qiekan - goicang - asog rift zone as the center of deposition and subsidence during the middle jurassic to the early creatceous . ( 1 ) during the middle - late jurassic , the rift zone was occupied by deep - water turbidites , radiolarian siliceous rocks , shallow - water carbonate rocks , clastic rocks and basic - ultrabasic rocks , while both sides of it by littoral and shallow marine elastic rocks and carbonate rocks 摘要位于班公湖怒江縫合帶與雅魯藏布江縫合帶之間的措勤盆地,在中侏羅世早白堊世期間具有以且坎古昌阿索裂谷帶為沉積、沉降中心向南北兩側展開的古地理格局:中晚侏羅世時期,裂谷帶內由深水濁積巖、放射蟲硅質巖和淺水碳酸鹽巖、碎屑巖巖片及基性超基性巖等組成;裂谷帶兩側由濱淺海相碎屑巖和碳酸鹽巖組成。

According to the fossils , we found one graptolite zone : mongraptus yukonensis - neomongraptus himalayensis zone ; two radiolarian combinations : entactinia - entactinosphaera , entqctinia itsukaichiensis combination , and three radiolarian zones : albaillella paradoxa zone , albaillella indensis zone and albaillella cartalla zone . 2 . the new cognition about the sedimentary environment of the original nanpihe formation 放射蟲可建立兩個組合和三個化石帶:晚泥盆世entactinia - entactinosphaera組合;早石炭世杜內期中期albaillellaparadoxa帶,杜內期晚期?維憲期早期albaillellaindensis帶,維憲期中期albaillellacartalla帶;晚二疊世entactiniaitsukaichiensis組合。

The pteridophyta fauna includes 3 genara and 6 species ( including 5 unnamed species ) , the graptolite fauna includes 3 genara and 4 species , the conodont fauna includes 10 genara and 17 species and the radiolarian fauna includes 12 genara and 28 species 鑒定后發現,植物共計3屬6種(其中包括5個未定種) ,筆石計有3屬4種,牙形石計有10屬17種,放射蟲計有12屬28種。

The geochemistry characteristic of fuchsia radiolarian silicalite indicates that they deposited in the of edge of oceanic basin near the continental margin , not the typical caontinental margin environment 從硅質巖的地球化學特征表現來看,紫紅色放射蟲硅質巖部分不是形成于典型的大陸邊緣環境中,而是形成于近大陸邊緣的洋盆邊緣環境。

Biogenic silica ( bsi ) is produced in the euphotic zone of the ocean by siliceous plankton such as diatoms or radiolarians 生物硅( bsi )的積累反映了生產力的長期和空間變化,它同時和全球c循環有著密不可分的關系。
