泰国北部三叠系Lampang群Doi Long组的有孔虫组合与沉积环境(英文)

A rich foraminiferal assemblage,consisting of abundant Aulotortus sinuosus and A.tumidus in association with Lamelliconus multispirus,Endoteba ex gr.controversa,E.ex gr.badouxi,Endotebanella kocaeliensis,Endotriada tyrrhenica,Endotriadella wirzi,Malayspirina fontainei,Ammobaculites rhaeticus,Diplotremina astrofimbriata,Agathammina austroalpina,and others,was found in the Doi Long Formation of the Triassic Lampang Group,Northern Thailand.These foraminifers suggest that the formation is referable to the Carnian(early Late Triassic),which is consistent with the age estimated by ammonoids.In microfacies,peloidal grainstone,bioclastic grainstone,sponge-microbial boundstone,and oolitic grainstone were recognized in the Doi Long Formation.Based on microfacies,three depositional facies,the lagoon facies,reef facies,and shoal facies,are recognized in this formation.These lines of evidence are suggestive that the Doi Long Formation was deposited in a reef or bank setting rather than a ramp setting.

泰国北部Inthanon带外来硅质岩块的中、晚二叠世放射虫:对与古特提斯消减有关的混杂岩形成时代的约束(英文)

The Inthanon Zone of Northern Thailand,originally proposed by Barr and Macdonald(1991),is characterized by the occurrence of Paleo-Tethyan pelagic sediments including Carboniferous-Permian seamount-type carbonate associated with oceanic

老挝北部宾夕法尼亚纪的一个新■类动物群(英文)

作者报道了一个小型■类动物群,包括Eostaffella? sp., Pseudoendothyra sp., Staffella pseudosphae-roidea Dutkevich, Neostaffella ( N.)sp ., Profusulinella bona Grozdilova et Lebedeva以及P.cf .prisca (Depart) ,此动物群是在老挝北部琅勃拉邦省西南部的Thong Phiang Vilay村附近的石灰岩山中发现的。根据Profusulinella bona和P.cf. prisca的出现,该动物群的时代可归到晚石炭世宾夕法尼亚纪巴什基尔期或莫斯科期最早期。这是在老挝北部对该时代■类动物群的首次报道。当前■类动物群证明琅勃拉邦地区和泰国北部的黎地区在地质上有重要的关系,表明老挝北部地区从地质构造上属于印度支那板块的边缘。
