Web14 apr. 2024 · Slab-derived sediment melt activity in the overlying lithosphere is crucial for element cycling and lithospheric evolution. To understand the nature of recycled sediment and its impact on the overlying lithosphere, we analyzed the Zn-Fe-Sr-Nd isotopic compositions of clinopyroxenites and a "glassy" xenolith from the North China Craton. Webasthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of …
