Latitudinal gradients in topography, relief, climate, and deformation have been used to suggest that climate-driven erosion has exerted a first order control on the development of the central Andes. We synthesize the spatial and temporal variations in denudation across the eastern Bolivian Andes (14-22°S) from new and existing estimates to test whether physical evidence exists to support the hy...

The processes leading to the assembly of Rodinia supercontinent through Grenvillian collisional orogeny are relatively well known. In contrast, accretionary orogenic occurring at periphery following poorly understood. To fill this gap, we have identified metamorphic rocks in Mongolia collage Central Asian Orogenic Belt, where numerous data testify for Meso- Neoproterozoic magmatic reworking. te...

The Alpine-Himalayan orogenic belt, the well-identified seismically active region in world, has been evidenced by occurrence of recent two devastating earthquake doublets 2015 central Nepal (MW 7.8 and MW 7.3) 2023 southeastern Turkey(MW 7.5). In this study, seismic ground motion characteristics damaging earthquakes namely doublet that occurred Himalaya Turkey eastern Mediterranean investigated...

The Cenozoic sedimentary cover from the Ghomaride Complex (Internal Rif Belt) has been studied in Tetuan area (N Morocco) where a suite of successions shallow-marine to deep-marine environments crops out. For that purpose stratigraphic relations and petrological geochemical signatures have analyzed. Sandstone suites overall succession are heterogeneous testify multi-source area, response accret...

K-Ar dating and 3He/4He 40Ar/36Ar analyses were conducted on samples of hydrothermal quartz from the Thongkai-Ok Au deposit in Vangtat orogenic belt southern Laos to study presence excess argon better understand origin ore-forming fluids. The age two separates yielded apparent dates 1040 1385 Ma. These ages are significantly older than estimated mineralization (~200 Ma) other regional geologic ...
