Web31 mrt. 2024 · The conductive zones are frequently explained by the presence of a small amount of partial melt, such as ~0.5 to 1 vol % of basalt or 0.05 to 0.5 vol % of carbonatite or carbonated basalt ( 3 – 8 ). Melt of these fractions, and even less, in the asthenosphere is likely to be compatible with petrological and physical constraints ( 9 – 11 ). The asthenosphere (from Ancient Greek ἀσθενός (asthenós) 'without strength') is the mechanically weak and ductile region of the upper mantle of Earth. It lies below the lithosphere, at a depth between ~80 and 200 km (50 and 120 mi) below the surface, and extends as deep as 700 km (430 mi). However, the lower boundary of the asthenosphere is not well defined.
