Salt structures can be used as an archive for tectonic and depositional processes all salt respond distinctively. Few studies have investigated the evolution of multi-stage structures, nevertheless, no previous study had systematically identified, mapped, nor classified, in a regional study. Decades hydrocarbon exploration heavily dense 3D seismic data available, make Southern North Sea one bes...

Abstract We present a geomorphic map of the Hypanis Valles watershed and deposit region at its terminus. mapped these two regions different scales: 1:2,000,000 for catchment (−5° to 10°N 300°–315°E) 1:500,000 (10°–13.0°N 313°–316.5°E). Our mapping provides new morphologic insights beyond previous efforts which used lower spatial resolution data. defined units based on morphology, albedo, therma...

Today, plate tectonics is the dominant tectonic style on Earth, but in a hotter Earth tectonics may have looked different due to the presence of more melting and associated compositional buoyancy as well as the presence of a weaker mantle and lithosphere. Here we review the geodynamic constraints on plate tectonics and proposed alternatives throughout Earth’s history. Observations suggest a 100...

Troodos is a classical ophiolite complex. It is proposed that the serpentinized harzburgites that now form the top of the mountain and represent the originally lowest part of the ophiolite sequence rose as a diapir. This diapiric rise is caused by the pervasive serpentinization of a suboceanic harzburgite, due to rock-sea water interaction. The serpentinization caused a 44% expansion of the roc...

Island arc lavas, erupted above subduction zones, commonly contain a geochemical component derived from partial melting of subducted sediment. It is debated whether this sediment melt signature, with enriched trace element concentrations and isotope ratios, forms at relatively low or high temperatures. Here we compile and analyse the geochemistry of metamorphosed sedimentary rocks that have bee...

Serpentinized mantle peridotites form prominent mountains, including the highest elevations of Troodos ophiolite in Cyprus (Mount Olympus, 1,952 m), but to date, only qualitative mechanisms have been proposed explain uplift rocks high altitudes. Serpentinization reactions between and water result profound changes rheology physical properties significant density reduction (∼900 kg/m3). Field obs...

We here use a 3D seismic reflection dataset from the Outer Kwanza Basin, offshore Angola to examine structure and growth of salt-detached strike-slip faults. The faults occur in four, up 13.8 km-long, NE-trending arrays that are physically linked by restraining bends releasing stepovers, which presently overlie Aptian salt base-salt relief related pre-salt faulting. suggest these formed accommo...
