Mapping global kimberlite potential from reconstructions of mantle flow over the past billion years.

PLoS ONE, 2022
Kimberlites are the primary source of economic grade diamonds. Their geologically rapid eruptions preferentially occur near or through thick and ancient continental lithosphere.

Active megadetachment beneath the western United States [PDF]

, 2008
Geodetic data, interpreted in light of seismic imaging, seismicity, xenolith studies, and the late Quaternary geologic history of the northern Great Basin, suggest that a subcontinental-scale extensional detachment is localized near the Moho.

Plume‐Modified Lithosphere Mantle Controlled the Cenozoic Sediment Thickness in the Tarim Basin

Geophysical Research Letters
The Cenozoic sediments are very thick in the southwest Tarim Basin and very thin in the northwest, but what controls these variations is unclear.

Generation of Continental Lithospheric Mantle by Tectonic Isolation of Oceanic Plate

Geochemistry, Geophysics, Geosystems, 2022
Continental formation models invoke subduction or plume‐related processes to create the buoyant, refractory character of continental lithospheric mantle (CLM).

The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]

, 2011
In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

Elastic properties of silicate melts: Implications for low velocity zones at the lithosphere-asthenosphere boundary. [PDF]

, 2017
Low seismic velocity regions in the mantle and crust are commonly attributed to the presence of silicate melts. Determining melt volume and geometric distribution is fundamental to understanding planetary dynamics.

Mantle heterogeneity during the formation of the North Atlantic Igneous Province: Constraints from trace element and Sr-Nd-Os-O isotope systematics of Baffin Island picrites [PDF]

, 2004
Sr-Nd-Os-O isotope and major and trace element data from ~62 Ma picrites from Baffin Island constrain the composition of mantle sources sampled at the inception of North Atlantic Igneous Province (NAIP) magmatism.

Investigating the Antarctic Lithosphere Through Sp Receiver Function Analysis

Geochemistry, Geophysics, Geosystems
To better understand the lithosphere of Antarctica, we imaged its lithosphere‐asthenosphere boundary (LAB) and crust‐mantle transition using Sp receiver functions from teleseismic events analyzed at individual stations and with common conversion point ...

Deep lithospheric structures along the southern central Chile Margin from wide-angle P-wave modellilng [PDF]

, 2009
Crustal- and upper-mantle structures of the subduction zone in south central Chile, between 42 degrees S and 46 degrees S, are determined from seismic wide-angle reflection and refraction data, using the seismic ray tracing method to calculate minimum ...

Identifying mantle lithosphere inheritance in controlling intraplate orogenesis [PDF]

Journal of Geophysical Research: Solid Earth, 2016
AbstractCrustal inheritance is often considered important in the tectonic evolution of the Wilson Cycle. However, the role of the mantle lithosphere is usually overlooked due to its difficulty to image and uncertainty in rheological makeup. Recently, increased resolution in lithosphere imaging has shown potential scarring in continental mantle ...
