More than 42 species of well-preserved Upper Devonian radiolarians have been obtained from cherts and siliceous shales in four sections(Chom Noi, Phu Kham Phe(P), Phu Kham Phe(C) and Pha Samyod) from the NE Thailand sector of the Loei fold belt, Indochina terrane. They include Ceratoikiscum sp. cf. planistellare Foreman, Helenifore laticlavium Nazarov & Ormiston, Astroentactinia sp. cf. paronae(Hinde), Stigmosphaerostylus herculea(Foreman), S. pusilla(Hinde), S. cf. vulgaris(Won), Trilonche davidi(Hinde), T. echinata(Hinde), T. elegans Hinde, T. hindea(Hinde), T. palimbola(Foreman), T. vetusta Hinde, Polyentactinia polygonia Foreman, Spongentactinella sp. cf. windjanensis Nazarov, Archocyrtium sp.?, Palaeoscenidium sp., Triaenosphaera sp., and others. Radiolarian faunas from these sections indicate a range from lower Frasnian to Famennian. Analyses of rare earth, trace and major elements suggest that the Upper Devonian chert and siliceous successions from Loei were deposited in a continental margin environment near to a volcanic arc. These successions contain distinctive weak negative Ce anomalies with strong positive Eu anomalies which differ from Upper Devonian cherts reported from northern Thailand, the Truong Son fold belt(Laos) and from South China. Negative Ce anomalies and low to moderate Lan/Cen ratios imply proximity between the Chom Noi and Phu Kham Phe(C), which were deposited in more distal parts of the depositional basin than the Pha Samyod and Phu Kham Phe(P) samples. Most of the Pha Samyod and Phu Kham Phe(P) samples exhibit high continental-derived trace element levels including Cr, Zr, Hf, Rb, Th and in part V, which supports close proximity to terrigenous sources. Paleozoic stratigraphic sequences of the Loei fold belt and geochemical results suggest that the Upper Devonian deep marine sequences in the Loei fold belt were deposited within a rifted, continental-margin basin, possibly a back-arc basin and not in a large oceanic basin as has been prev

Middle Triassic Radiolarians from Cherts/Siliceous Shales in an Extensional Basin in the Sukhothai Fold Belt,Northern Thailand

Journal of Earth Science 2017年第1期28卷 9-28页

More than thirty species of radiolarians are described from maroon chert and siliceous shales from the Den Chai and Santisuk sections in the east of the Sukhothai fold belt. The fauna obtained from Den Chai comprises Muelleritortis cochleata cochleata, M. cochleata tumidospina, M. expansa, Triassocampe deweveri, T. coronata, T. scalaris, Annulotriassocampe companilis, A. multisegmantatus, A. sulovensis, Pseudostylosphaera coccostyla coccostyla, P. imperspicua, Canoptum inornatus, C. levis, Corum kraineri, Spongoserrula rarauana, Orbiculiforma karnica and others. The assemblage may be correlated with those reported in the Fang-Chiang Dao and Lumphun areas in the north of Thailand and in the ChangningMenglian belt of western Yunnan, South China and suggests a late Ladinian（Middle Triassic） age. The radiolarian fauna from the Santisuk Section comprises Muelleritortis cochleata cochleata, M. sp., Striatotrissocampe nodosoannulata, Triassocampe. deweveri, T. sp., Pseudogodia？ sp., Pseudostylosphaera coccostyla coccostyla, Archaeocenosphera sp., Annulotriassocampe multisegmantis, Pseudostylosphaera sp., and others which indicates a late Ladinian age. Middle Triassic radiolarian chert and siliceous shale from Den Chai and Santisuk are interpreted as having been deposited in an extensional continental margin within the Sukhothai fold belt and not in the Devonian–Permian back-arc basin of the Nan suture. These deep marine sequences were deposited in a subsiding continental margin in the Lampang-Phrae Basin. We consider these sequences to be part of the Hong Hoi Formation（Anisian–Ladinian） of the Lampang Group which, in turn, may be compared to the Choushui Formation and other associated Middle Triassic formations in the Simao Basin of South China.

通过对暹缅马苏和澳大利亚奥陶系层序和动物群的研究,对早古生代期间泰国和马来西亚(暹缅马苏地块)曾毗邻澳大利亚这一假说进行了验证.那些生长在较窄的地理环境中的鹦鹉螺类在两个地区惊人地相似,属一级辛普生系数为0.92.盘珠角石类的两个新属仅限于这两个地区,而Georgina及Mesaktoceras则仅见于这两地区以外的西藏.两地的腹足类、多板类、喙壳类软体动物非常相似.奥陶纪的腕足动物门亦相似(包括Spanodoata).另外,两地的晚寒武世三叶虫化石、奥陶纪牙形石及层孔虫类亦非常相似.研究过程中无论是在北澳大利亚,还是在遏缅马苏均未发现其年代比上怀特罗克阶更新的动物群,两地大部分地区从上怀特罗克阶到上奥陶统之间的层序可能缺失.这些动物群的极度相以性为我们提供了关于早古生代期间暹缅马苏地块曾毗邻澳大利亚这一假说的较好证据.华北、东南亚、西藏和澳大利亚在动物群上的相似性亦表明,在早古生代,这些地块的地理位置很接近.
