This work documents for the first time prehistoric, but morphologically pristine, Emad Deh rock avalanche of Zagros Mountains. The ca. 420 Mm 3 was initiated as a rockslide on dip slope affecting weak unit marls with interbedded limestones overlain by thick and competent limestone formation. is located northern limb growing Gavbast Anticline at edge inflating Dome, related to buried salt diapir...

Abstract A first-order observation of convergent margin volcanism is that continental arc stratovolcanoes have substantially elevated incompatible element abundances and notable fractionations certain ratios compared to oceanic stratovolcanoes. Models account for these differences include (1) a greater influence differentiation contamination due thicker crust, (2) variable slab flux controlled ...

This work studies salt-detached fold-and-thrust belts involving minibasins by means of physical analogue modeling. The experimental set up consist a series and diapirs built downbuilding into regular polygonal framework. minibasins-diapir framework were then submitted to contraction, for some examples accompanied different rates syncontractional sedimentation. We aimed at evaluating the influen...

The most enigmatic problems with the nearly 200 salt domes pierced in the Persian Gulf and in the Zagros Mountain Ranges (ZMR) in southern Iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. In the ZMR, structural anomalies are frequently associated with similar facies dis...

The Jinshajiang–Ailaoshan–Song Ma orogenic belt (JASB), as a vital segment of the eastern Paleo-Tethyan tectonic zone, is one most important zones in which to study evolution. We have undertaken an integrated geochronological, petrological, and geochemical mafic rocks from JASB reveal subduction closure processes Ocean during Permian Triassic. In conjunction with previous magmatic metamorphic r...

Fluid systems in inverted rifted margins are challenging to interpret because fractures formed before compression were often reactivated acting as fluid pathways new ones formed. Deciphering the fracture and flow history such complex settings has key implications for prediction of distribution mineral resources. As an example, we reconstruct evolution a portion Pyrenean rift, Upper Pedraforca t...

The structure of the southwestern branch Alpine orogen is affected by extensive Late Triassic evaporites. These evaporites have been involved in polyphased salt tectonics since early Liassic, coeval with Tethyan rifting, and are décollement level for thrusts external parts during orogeny. role this arc re-evaluated order to determine relative importance deformation related motion respect main c...
