On the tectonic evolution of the mainland South-east Asia, researchers pay more attention to the Chiang Mae and Nan belts. Investigation on the Loei Belt is usually ignored. Therefore, there are different opinions about its naming and evolution: Loei Fold-belt located at the western margin of the Indochina Block during the Late Paleozoic and Triassic (Bunopas, 1981; Man-tajit, 1999), Petchabun Fold-belt between the Khao Khwang and Pha Nok Khao carbonate plateforms dur-ing the Carboniferous and Permian (Helmcke, 1983, 1986; Altermann, 1989, 1991), Loei Suture Zone be-tween the Nakhon Thai and Indochina blocks during the Late Paleozoic and early Mesozoic (Charusiri et al., 1997, 2002; Chutakositkanon et al., 1997, 1999) 相似文献

Based on our extensive fieldwork in southwestern Yunnan and northern Thailand, followed by detailed stratigraphic and paleontological studies, we propose that the Triassic Simao Basin in Yunnan can be correlated with the Triassic Lampang–Phrae Basin in Thailand. Strata equivalent to those in the southern Lancangjiang sub-basin have not been identified in northern Thailand. We consider that during the Triassic the Simao and the Lampang–Phrae Basins belonged to the same tectonopaleogeographic unit. The orogenic belt to the east of this unit includes the Nan–Uttaradit and Ailaoshan sutures. The ‘Shan–Thai Block’ in northern Thailand, can be divided from east to west into the Sukhothai, the Inthanon, and the Shan terranes. According to tectonopaleogeographic correlation, our results support the idea that the Sukhothai Terrane, including the Lampang–Phrae Basin, belongs to the Cathaysian domain and not to Gondwana domain, and that the geosuture corresponding to the Changning–Menglian Suture in Yunnan must lie to the west of the Sukhothai Terrane in Thailand. 相似文献

The Shan-Thai Block, regarded traditionally as awhole geotectonic unit by the geologists engaged inthe study of geotectonic evolution of Southeast Asia, issituated to the west of the Ailaoshan and Nan-UttaraditSutures and to the east of the Shan Boundary Faults,and covers southwestern Yunnan, eastern Myanmar,most of Thailand, northwestern Laos, western Malay-sia, and Sumatra[1,2] (fig. 1). However, recent researchshows that it consists of two continental terranes fromGondwana and Cathay… 相似文献
