Abstract Duplexing plays important roles in the evolution of fold-and-thrust belts and accretionary wedges, causes internal shortening system, which then impacts both rates frontal advance seismic-moment deficit. Nevertheless, significance this has not yet been highlighted previous studies Himalaya or elsewhere. We invoke geometric solutions to constrain ratio transferred slip (R; i.e., updip d...

We constrain orientations of the horizontal stress field from borehole image data in a transect across Hikurangi Subduction Margin. This region experiences NW-SE convergence and is site recurrent slow slip events. The direction maximum E-W at an active splay thrust fault near subduction margin trench. trend changes to NNW-SSE forearc trench slope basin on offshore accretionary wedge, NE-SW onsh...

We analyze records of ambient seismicity from Central Chile to investigate mechanisms tectonic erosion and accretion in an Andean margin. The seismograms were recorded by a temporary network 39 stations deployed between 32.5°S 34.0°S April November 2017. employ automatic earthquake catalogue generator estimate 8463 P-wave 5482 S-wave arrival times 924 hypocenters, which then used jointly determ...

The assembly of West Gondwana supercontinent involved several complex processes that led to the formation Hoggar shield during Panafrican-Brasiliano event. We present first petro-geochemical, geochronological and field data serpentinite lenses exposed along In-Tedeini domain, within deformed talc-schist magmatic-sedimentary formations. serpentinites preserved main characteristics their parent p...

Impact ejecta from the Albion Formation are exposed in northern Belize. The ejecta come from the outer portion of the continuous ejecta blanket of the Chicxulub crater, which is located 360 km to the northwest. The basal unit of the Albion Formation is a 3⁄41-m-thick clay and dolomite spheroid bed composed of up to four discrete flows. The clay spheroids are altered impact glass, and the dolomi...

The natural emission of methane-rich fluids from the seafloor, known as cold seepage, is a widespread process at modern continental margins. studies on present-day seepages provide high-resolution datasets regarding fluid plumbing system, biogeochemical processes in sediment, seafloor seepage distribution and ecosystems. However, long-term (hundreds thousands to millions years) evolution remain...
