The Rioni foreland fold-and-thrust belt is part of the Greater Caucasus pro-wedge and one most important examples collision-driven far-field deformation Arabia-Eurasia convergence zone. Here we show structural style based on seismic reflection profiles regional balanced cross-section. main within represented by a set fault-propagation folds, duplexes, triangle cross-section shows that folds abo...

The geological structure of Zhong-7 well and Zhong-14 is the Hengshanpu section thrust belt in western margin Ordos Basin, there have been few construction wells this area past two years. During wells, formation stability entire was extremely poor, especially Shiqianfeng. following strata collapsed seriously frequently encountered blockages during tripping. construction, measures such as optimi...

Abstract This study aims to analyze the lineaments using field data and a remote sensing approach, describe their relationship with folds, faults, regional tectonic stress of central Sulaiman Fold-Thrust Belt. Joint data, from nine anticlines, has been collected scanline method classified into three sets (JS1, JS2, JS3) based on geometrical relationships. Lineaments extracted 30 m digital eleva...

the larger benthic foraminifera gyroconulina columellifera schroeder & darmoian, 1977 (type-locality: maastrichtian aqra formation of iraq) is described for the first time from two sections of the maastrichtian tarbur formation of the zagros fold-thrust-belt, sw iran. new details on its wall microstructure are provided. the microfacies is represented by bioclastic wacke-/pack-/grainstones with ...

Models of how high elevations formed across Tibet predict: (a) the continuous thickening of a "viscous sheet"; (b) time-dependent, oblique stepwise growth; and (c) synchronous deformation across Tibet that accompanied collision. Our new observations may shed light on this issue. Here, we use 40Ar/39Ar and (U-Th)/He thermochronology from massifs in the hanging walls of thrust structures along th...
