新疆東準噶爾卡拉麥里碰撞帶志留-泥盆系生物地層化石生物群時序 新疆東準卡拉麥里碰撞帶是國內重大基礎理論研究的熱點之一尤其碰撞帶時限問題存在不同觀點[1-5]。長期以來該地區一直存在“構造熱”對地層的研究卻十分滯后尤其對志留-泥盆系地層研究更少對泥盆地層的研究更是從未涉及。卡拉麥里碰撞帶南緣志留系由白山包組由老溝組(新建)組成泥盆系紅柳溝組泥盆下中統卡拉麥里組泥盆上統克安庫都克組組成。

摘要:
通過精細的生物地層學工作,從時代和生物群組合入手,厘定了志留-泥盆各時期的巖石地層單位時序,在卡拉麥里碰撞帶南緣建立較為合理的地層序列中上志留統白山包組第一段可建立扭圖瓦貝Tuvaestrophia sp.)-薄扭貝Leptostrophia sp.)- 原始戟貝Protochonetes sp.)生物群組合第二段大型圖瓦貝Tuvaella gigantea Tschernyschew)-近平無洞貝(相似種)Atrypa cf. depressa Zhang)-蓋嘴貝Stegerhynchus sp.)生物群組合,第三段大型圖瓦貝Tuvaella gigantea Tschernyschew)-拉氏圖瓦貝Tuvaella rackovskii Tschernyschew)-扁平薄皺貝Leptaena cf. depressa)-新疆高面石燕Tannuspirifer xinjiangensis Zhang)生物群組合上志留統老溝組小鴿無洞貝Atrypella cf. columbella Barrande)-單褶準無窗貝Athyrisina cf. uniplicata Grabau) -安嘎西蓋嘴貝tegerhynchus angaciensis Tschernyschew)生物群組合下泥盆統紅柳溝組動物群組合,下中卡拉麥里組)動物群組合,上統克安庫都克組出現Prelepidondron sp.)。志留-泥盆地層單位時序建立,對卡拉麥里碰撞帶志留-泥盆具有。
Abstract:
Based on the precise biostratigraphic work and combined with fossil biota and their geological periods, it is redefined the sequence in Silurian -Devonian lithostratigraphic units in southern margin of the Kalamaili collision zone, east Junggar. The result shows that the assemblages of fossil biota in the first section of the Baishanbao Formation in middle-upper Silurian can be established as Tuvaestrophia sp. - Leptostrophia sp. -Protochonetes sp, the second and third sections can be established as Tuvaella gigantea Tschernyschew--Atrypa cf. depressa Zhang-Stegerhynchus sp. and Tuvaella gigantea Tschernyschew- Tuvaella rackovskii Tschernyschew- Leptaena cf. depressa- Tannuspirifer xinjiangensis Zhang., respectively. The assemblages of fossil biota of the Laogou Formation in upper Silurian can be established as Atrypella cf. columbella Barrande- Athyrisina cf. uniplicata Grabau - Stegerhynchus angaciensis Tschernyschew, the Hongliugou Formation in lower Devonian can be established as Steatothamnopora sp. - Striatopora sp. - Parathamnopora sp. and Kalamaili Formation of lower-middle Devonian is established as Leptocoelia cf.sinica Su- Enterolasma sp. - Diplochone sp. In addition, Prelepidondron sp. is discovered in Keankuduke Formation in upper Devonian. The establishment of biological stratigraphic units in Silurian-Devonian in this area is important to study the Silurian-Devonian biostratigraphy in Kalamaili collision zone
