Water solubility in aluminous orthopyroxene and the origin of Earth's asthenosphere.
Plate tectonics is based on the concept of rigid lithosphere plates sliding on a mechanically weak asthenosphere. Many models assume that the weakness of the asthenosphere is related to the presence of small amounts of hydrous melts. However, the mechanism that may cause melting in the asthenosphere is not well understood. We show that the asthenosphere coincides with a zone where the water sol...
متن کاملElectrical conductivity of orthopyroxene: Implications for the water content of the asthenosphere
Electrical conductivity of minerals is sensitive to water content and hence can be used to infer the water content in the mantle. However, previous studies to infer the water content in the upper mantle were based on pure olivine model of the upper mantle. Influence of other minerals particularly that of orthopyroxene needs to be included to obtain a better estimate of water content in view of ...
متن کاملVariation of Lithosphere-Asthenosphere boundary beneath Iran by using S Receiver function
The current geological and tectonic setting of Iran is due to the ongoing convergence between the Arabian and Eurasian Plates, which resulted in the formation of the Iranian plateau, mountain building, extensive deformation and seismicity. The Iranian plateau is characterized by various domains including the continental collision and the oceanic plate seduction. Based on S receiver functions ar...
متن کاملThe fate of water within Earth and super-Earths and implications for plate tectonics
The Earth is likely to have acquired most of its water during accretion. Internal heat of planetesimals by short-lived radioisotopes would have caused some water loss, but impacts into planetesimals were insufficiently energetic to produce further drying. Water is thought to be critical for the development of plate tectonics, because it lowers viscosities in the asthenosphere, enabling subducti...
متن کاملOrigin and hydrogeochemical evolution of Azarshahr travertine springs, NW Iran
1-Introduction Travertines are limestones that form where hot groundwaters rich in calcium and bicarbonate emerge at springs. Travertines cover a large area southwest of Azarshahr (East Azarbaijan province), in some parts of which active springs are currently settling travertine. One of the main questions about travertine springs is their origin, as well as the secondary processes that have ch...
