Plume‐Induced Subduction Initiation: Single‐Slab or Multi‐Slab Subduction?

Geochemistry, Geophysics, Geosystems, 2020
Initiation of subduction following the impingement of a hot buoyant mantle plume is one of the few scenarios that allow breaking the lithosphere and recycling a stagnant lid without requiring any preexisting weak zones.

Altered Mantle Fabric Beneath the Mid‐Continent Rift

Geochemistry, Geophysics, Geosystems, 2021
We present new, densely sampled shear‐wave splitting results from southern Minnesota and adjacent areas of neighboring states, sampling the southwestern limit of the Archean Superior Province and straddling the Proterozoic Mid‐Continent Rift (MCR).

Thermal Structure of Eastern Australia's Upper Mantle and Its Relationship to Cenozoic Volcanic Activity and Dynamic Topography

Geochemistry, Geophysics, Geosystems, 2021
Spatio‐temporal changes of upper mantle structure play a significant role in generating and maintaining surface topography. Although geophysical models of upper mantle structure have become increasingly refined, there is a paucity of geologic constraints

The thermal state and interior structure of Mars [PDF]

, 2018
©2018. American Geophysical UnionThe present‐day thermal state, interior structure, composition, and rheology of Mars can be constrained by comparing the results of thermal history calculations with geophysical, petrological, and geological observations.

Geochemistry and tectonic development of Cenozoic magmatism in the Carpathian–Pannonian region [PDF]

, 2011
This review considers the magmatic processes in the Carpathian–Pannonian Region (CPR) from Early Miocene to Recent times, as well as the contemporaneous magmatism at its southern boundary in the Dinaride and Balkans regions.

Earth's Continental Lithosphere Through Time

, 2017
The record of the continental lithosphere is patchy and incomplete; no known rock is older than 4.02 Ga, and less than 5% of the rocks preserved are older than 3 Ga. In addition, there is no recognizable mantle lithosphere from before 3 Ga. We infer that

Lithospheric controls on melt production during continental breakup at slow rates of extension: Application to the North Atlantic

, 2009
Rifted margins form from extension and breakup of the continentallithosphere. If this extension is coeval with a region of hotter lithosphere,then it is generally assumed that a volcanic margin would follow.

An Evaluation of Proposed Mechanisms of Slab Flattening in Central Mexico [PDF]

, 2010
Central Mexico is the site of an enigmatic zone of flat subduction. The general geometry of the subducting slab has been known for some time and is characterized by a horizontal zone bounded on either side by two moderately dipping sections.

Welcome to Lithosphere [PDF]

Lithosphere, 2009
Dear Readers, So, do we really need another journal full of papers on solid earth science taking up shelf space in our offices and competing for scarce subscription funds in our libraries? The answer to this question was, in a sense, addressed 150 years ago by Charles Darwin in a somewhat ...
