The Mawat ophiolite complex is of Cretaceous period as a residue oceanic crust covers about 200 km2, Northeastern Iraq.. serpentinite rocks are exposed diapir in the northeastern suture Zagros zone Iraq near Beetwat village, field study and petrography reveal two types serpentinite, shear massive, with three serpentine varieties. affected by secondary processes such diagenesis, metamorphism hyd...

Oceanic transform faults display fewer and smaller-magnitude earthquakes than expected for their length. Several mechanisms have been inferred to explain this seismic slip deficit, including increased fault zone damage resulting in elevated fluid flow, the alteration of olivine serpentine. However, date, these possible are not supported by direct observation. We use micro kilometer scale observ...

In recent years, the mélange model has been increasingly considered as an important way to transfer slab components arc sources in modern subduction zones. This differs from classic fluid/melt metasomatism that it invokes physical mixing of bulk sediment, altered oceanic crust (AOC), serpentinite, and mantle wedge at slab-mantle interface. However, due lack subducted sediment compositions, not ...

An abundance of trace metals in the environment is a characteristic property of only a few terrestrial ecosystems. Serpentinite contains high concentrations of trace metals especially Ni and Cr that are released by weathering. Other natural sources of trace metals are volcanic eruptions and the deposition of marine aerosols. In the soil some trace metals are strongly adsorbed to the mineral mat...
