Uplift of the western Kunlun range results from Indian indentation into Eurasia and induced underthrusting Tarim lithosphere. This keeps pace with migration foreland basin. The basin-scale sequences provide a decipherable record migration. To quantify underthrusting, we analyzed ∼323.2-km-long seismic profile crossing middle segment foreland. We traced reflectors to investigate architecture ass...

The previous understanding of Tian Shan's lithospheric architecture can be summarized into three models: unidirectional underthrusting, bidirectional and mantle upwelling. These models make distinctive predictions regarding the migration subsidence histories foreland basins on either side range. Seismic profiles crossing both document their history. We analyze a seismic profile across Southern ...

The Himalaya, the Earth's largest active orogen, produces a deep but relatively unexplored foreland basin by loading Indian Plate. Newly available two-dimensional seismic data (ca. 5,180 line km) spanning 900 km of Nepali lowlands allow mapping and interpretation several regional subsurface markers in two-way-travel time estimated depth. Isopach maps for major intervals us to interpret interpla...

Early–Middle Pennsylvanian (late Carboniferous) age coalbearing strata in Europe can be found in two general depositional settings (OPLUŠTIL & CLEAL, 2007; CLEAL et al., 2010, 2011). The most extensive deposits were formed in paralic settings, most notably on the Variscan Foreland and associated basins between the British Isles and northern Turkey, in the Donets Basin of eastern Europe, and the...

Orogenic growth, characterized by formation and forward propagation of fold-thrust belts foreland basins, is predicted wedge models thrust systems. The growth the Nanpanjiang belt basin system Indosinian orogenic in southwestern South China remains poorly understood. development underappreciated due to few constraints on structural styles, kinematics ages.

Abstract. The Late Cretaceous intraplate shortening event in central western Europe is associated with a number of marine basins relatively high amplitude and short wavelength (2–3 km depth 20–100 width). In particular, the Harz Mountains, basement uplift on single, steeply dipping thrust, have filled adjacent Subhercynian Basin their erosive product, proving that two were related synchronous. ...

Analogue experiments were carried out to get insights into the processes governing positive inversion during the foreland propagating thrust tectonics in the southern Serra do Espinhaço, a Brasiliano/Panafrican foldthrust belt in southeast Brazil. In particular, model listric half-grabens were inverted by applying contractional displacement to the footwall blocks. We investigated two different ...
