[1] The development of topography within and erosional removal of material from an orogen exerts a primary control on its structure. We develop a model that describes the temporal development of a frontally accreting, critically growing Coulomb wedge whose topography is largely limited by bedrock fluvial incision. We present general results for arbitrary initial critical wedge geometries and in...

BACKGROUND Controversy exists over whether or not single-needle liver biopsies are sufficient to compare histological parameters in patients with non-alcoholic fatty liver disease. AIMS To identify sampling variability, we biopsied four liver specimens per patient, based on biopsy size (needle vs wedge) and location (left vs right lobe), immediately prior to bariatric Roux-en-Y gastric bypass...

Tectonic inversion of passive margins is a common but poorly documented process preceding subduction inception. We perform here comprehensive land-sea experimental modeling this key by reproducing the morphotectonic and sedimentary evolution central Algerian margin over last 6 Myr. Our approach based on scaled analog models integrating interactions between crustal shortening surface processes, ...

Authigenic ferrimagnetic iron sulfides, essentially greigite (Fe 3 S 4 ), are commonly found in gas hydrate-bearing marine sediments of active accretionary prisms. Greigite is a by-product, either intracellular or extracellular, microbial activity, and therefore provides good indication processes which closely related to the occurrence hydrate. A high-resolution rock magnetic study was conducte...

The Tethyan Himalaya is the fourth metallogenic belt discovered to date within Tibetan Plateau and contains chromite, gold Sb–polymetallic mineralization. records a series of complex tectonic–magmatic events that include break-up, subduction, collision, detachment, obduction Eastern Gondwana continent, all which generated ideal conditions for ore formation. However, this area remains under-expl...

A non-physical wedge generates a spatial dose distribution similar to that produced by a physical wedge without a physical filter in the photon beam. Instead, an exponential fluence profile is produced via motion of one of the collimating jaws. Proposed in the late 1970s, nonphysical wedges have been implemented on both Varian and Siemens’ accelerators as the Varian Dynamic Wedge (DW) and Sieme...

Introduction: The Bangong-Nujiang Suture Zone (BNSZ) in central Tibet is a remnant of the Ocean that records its entire Wilson Cycle. model divergent double-sided subduction (DDS) crucial for elucidating evolution tectonomagmatic activity on both sides BNSZ and understanding why no high-pressure metamorphic rocks occur BNSZ. However, DDS geodynamics remain poorly constrained. In particular, the...
