The Cathles Parameter (Ct): A Geodynamic Definition of the Asthenosphere and Implications for the Nature of Plate Tectonics

Geochemistry Geophysics Geosystems, 2018
A weak asthenosphere, or low‐viscosity zone (LVZ), underlying Earth's lithosphere has played an important role in interpreting isostasy, postglacial rebound (PGR), and the seismic LVZ, as well as proposed mechanisms for continental drift, plate tectonics,

The development of magmatism along the Cameroon Volcanic Line: evidence from seismicity and seismic anisotropy [PDF]

, 2014
The Cameroon Volcanic Line (CVL) straddles the continent-ocean boundary in West Africa but exhibits no clear age progression. This renders it difficult to explain by traditional plume/plate motion hypotheses; thus, there remains no consensus on the ...

Recovery of an oxidized majorite inclusion from Earth’s deep asthenosphere

Science Advances, 2017
Novel discovered majorite from a depth of at least 380 km provides unique window into the redox state and dynamics of the mantle. Minerals recovered from the deep mantle provide a rare glimpse into deep Earth processes.

THE MIOCENE AND DEVONIAN MAGMATISM AT THE JUNCTION BETWEEN THE TUVA-MONGOLIAN MASSIF AND SIBERIAN CRATON: COMMON COMPONENT OF MANTLE SOURCES AND ITS ORIGIN

Геодинамика и тектонофизика, 2015
Devonian dikes of the Urik-Belaya and Shagayte-Gol-Urik zones and Miocene lavas of the Urik volcanic field are spatially associated with each other at the structural junction between the Neoproterozoic Tuva-Mongolian massif and Siberian craton.

Evolving force balance during incipient subduction [PDF]

, 2004
Nearly half of all active subduction zones initiated during the Cenozoic. All subduction zones associated with active back arc extension have initiated since the Eocene, hinting that back arc extension may be intimately associated with an interval ...
