[1] Basement-cored uplift provinces are often characterized by high-angle reverse faulting along preexisting crustal heterogeneities, which may greatly affect the mechanics of deformation and the coupling between erosion and orogenic structure. Herein we construct a coupled deformation-erosion model to understand the mechanics and erosion of mountain belts in which the spatial distribution of d...
The Cenozoic sedimentary cover of the Malaguide Complex (Internal Betic Cordillera, Spain), in Almería and Málaga areas, consists a suite successions from continental shallow-marine to deep-marine environments. Structural stratigraphic relations, petrological geochemical signatures reveal evolution (CMC) pre-orogenic (Palocene-Eocene) syn-orogenic (Oligocene-Early Miocene) stages. Sandstones de...
Abstract Orogenic belts have been thought to form through plate convergence, involving subduction of oceanic lithosphere at continental margins (accretionary orogens), which may ultimately lead ocean closure and continent-continent collision (collisional orogens). Intraplate orogens away from known, but the mechanisms controlling their evolution are poorly understood. The South China craton, in...
In the mid‐1980s, advances in understanding the mechanics of the fold‐and‐thrust belts that flank many collisional mountain ranges set the stage for a fundamental change in our appreciation of the role of erosion in the tectonic evolution of mountain ranges. A combination of sandbox experiments, analytical treatments of stress state and field observations showed that fold‐and‐thrust belts form ...
The Lachlan Fold Belt is well known for its complex deformational history, with a number of orogenic events and associated structural styles recognised. Recent syntheses of this orogenic evolution have emphasised the difficulty of identifying fold-belt-wide deformational episodes and have inferred the existence of diachronous deformation zones with an overall merging of episodic orogenic events...

Sediment accumulation rates in foreland basins result from a complex interplay between surface and deep processes both the exhumed relief domain sedimentary basins. The growth decay of mountain belt during orogenic post-orogenic phases have been largely studied, thanks to thermochronological structural studies. response preserved sediments surrounding is well known terms filling patterns archit...
Where plates converge, one-sided subduction generates two contrasting thermal environments in the subduction zone (low dT/dP) and in the arc and subduction zone backarc or orogenic hinterland (high dT/dP). This duality of thermal regimes is the hallmark of modern plate tectonics, which is imprinted in the ancient rock record as penecontemporaneous metamorphic belts of two contrasting types, one...
