Experimental evidence supports mantle partial melting in the asthenosphere

J Chantel, G Manthilake, D Andrault, D Novella… - Science …, 2016 - science.org
The low-velocity zone (LVZ) is a persistent seismic feature in a broad range of geological
contexts. It coincides in depth with the asthenosphere, a mantle region of lowered viscosity …

Nominally anhydrous minerals and Earth's deep water cycle

JR Smyth, SD Jacobsen - Earth's deep water cycle, 2006 - Wiley Online Library
Earth is unique among the Terrestrial planets in having liquid water on its surface. Water
controls the entire character of the biology and geology of the planet. Without liquid water …
