Oceanic Lithosphere/Asthenosphere - Evolution and Dynamics ?
Scope
The life cycle of oceanic lithosphere is controlled by asthenospheric dynamics, and vice versa. Transdisciplinal study is essential for the true understanding of the lithosphere/asthenosphere as a whole. We invite contributions from the studying the seismology, electrical conductivity, geodynamics, mineral physics, petrology, and geochemistry of the lithosphere, the asthenosphere and/or the boundary between.
