New data on the „Indosinian“ Orogeny from Central Thailand

open access: yesGeologische Rundschau, 1983
The main aspects of the geosynclinal and orogenic evolution of the Petchabun foldbelt in Central Thailand are described. This area was previously thought to be deformed by the „Indosinian“ (Triassic) orogeny. The new data show that the main orogenic event in Thailand can be dated: Post Lower Permian — Pre Uppermost Permian.

Asphalt features and gas accumulation mechanism of Sinian reservoirs in the Tongwan Palaeo-uplift, Sichuan Basin

open access: yesNatural Gas Industry B, 2015
Breakthroughs have been made in natural gas exploration in Sinian reservoirs in the Tongwan Palaeo-uplift, Sichuan Basin, recently. However, there are disputes with regard to the genetic mechanisms of natural gas reservoirs.

Zircon U-Pb Geochronology and Uranium-Production Capacity of the Taoshan Complex in Southern Jiangxi

open access: yesYankuang ceshi, 2014
The Taoshan granite complex located at the North-East part of the Nanling region, hosts the largest granite-related uranuim ore field in China. Baohuashan granite and Huangpi granite are two major components of the Taoshan granite complex.

Was the Indosinian orogeny a Triassic mountain building or a thermotectonic reactivation event?

open access: yesComptes Rendus. Géoscience, 2007
The underlying cause of Indosinian thermotectonism remains unclear, in part because the term has also been adopted to explain Triassic orogenesis across southern China. This paper puts forward the case that use of the term Indosinian should be confined to Vietnam where deformation is linked to continental accretion as opposed to southern China where ...

Progressive Indosinian N-S deformation of the Jiaochang structure in the Songpan-Ganzi fold-belt, Western China. [PDF]

open access: yesPLoS ONE, 2013
Integrated field data, microstructural and three-dimensional strain analyses are used to document coaxial N-S shortening and southward increase in deformation intensity and metamorphism at the Jiaochang structure. Two episodes of deformation (D1,D2) with

Relationship between gas reservoir distribution and structural system of upper Triassic Xujiahe Fm in the Sichuan Basin

open access: yesNatural Gas Industry B, 2019
The gas reservoir of Upper Triassic Xujiahe Fm in the Sichuan Basin is characterized by “accumulation in the early stage, entrapment in the middle stage and activation in the late stage”.

Discovery of Bozhong 13-2 Archean large monoblock volatile buried hill oilfield and its oil and gas exploration significance

open access: yesNatural Gas Industry B, 2021
The hydrocarbon accumulation pattern of the Mesozoic covered Archean buried hill in the Bohai Oilfield was not clarified before, which restricts the oil and gas exploration progress in this area. In recent years, reservoir development modes and reservoir

Permo-Triassic detrital records of South China and implications for the Indosinian events in East Asia [PDF]

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 2017
Abstract Provenance analyses of Lower to Middle Triassic strata from the Greater Youjiang Basin along with the Permian strata of Hainan Island, provide a record of the collisional assembly of the South China Craton and Indochina Block and their incorporation into Asia.

Geochemistry and Geochronology of Magmatic Rocks in Southwestern and Northeastern Cambodia: Implications for the Tectonic Evolution and Metallogenesis of the Loei Fold Belt

open access: yesGeological Journal, EarlyView.
The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.

LA-ICP-MS U–Pb ages of detrital zircons from Middle Jurassic sedimentary rocks in southwestern Fujian: Sedimentary provenance and its geological significance

open access: yesOpen Geosciences, 2020
In order to determine the tectonic regime change of the early Mesozoic in the South China Block, this study analyzed sedimentary rocks in the Middle Jurassic of southwestern Fujian by modal analysis of sandstones, elemental geochemical analysis of ...
