Metamorphism of Venus as driver of crustal thickness and recycling [PDF]

Nature Communications
The composition and thickness of the venusian crust and their dependence on thermal gradients and geodynamic setting are not well constrained. Here, we use metamorphic phase transitions and the onset of melting to determine the maximum crustal thickness ...

Quantifying crustal thickness over time in magmatic arcs. [PDF]

Sci Rep, 2015
AbstractWe present global and regional correlations between whole-rock values of Sr/Y and La/Yb and crustal thickness for intermediate rocks from modern subduction-related magmatic arcs formed around the Pacific. These correlations bolster earlier ideas that various geochemical parameters can be used to track changes of crustal thickness through time ...

Mercury's Crustal Thickness and Contractional Strain. [PDF]

Geophys Res Lett, 2021
AbstractThe crust of Mercury has experienced contraction on a global scale. Contractional deformation is expressed by a broadly distributed network of lobate thrust fault scarps. The most likely principal source of stress is global contraction from cooling of Mercury's interior.

Magmatic intrusions control Io's crustal thickness [PDF]

Journal of Geophysical Research: Planets, 2020
Io, the most volcanically active body in the solar system, loses heat through eruptions of hot lava. Heat is supplied by tidal heating and is thought to be transferred through the mantle by magmatic segregation, a mode of transport that sets it apart ...

Quantifying Crustal Thickness in Continental Collisional Belts: Global Perspective and a Geologic Application [PDF]

Scientific Reports, 2017
We present compiled geochemical data of young (mostly Pliocene-present) intermediate magmatic rocks from continental collisional belts and correlations between their whole-rock Sr/Y and La/Yb ratios and modern crustal thickness. These correlations, which

Using Tidally‐Driven Elastic Strains to Infer Regional Variations in Crustal Thickness at Enceladus [PDF]

Geophysical Research Letters, 2023
Constraining the spatial variability of the thickness of the ice shell of Enceladus (i.e., the crust) is central to our understanding of the internal dynamics and evolution of this small Saturnian moon.

Advances in Deformable Plate Tectonic Models: 1. Reconstructing Deformable Continental Blocks and Crustal Thicknesses Back Through Time

Geochemistry, Geophysics, Geosystems, 2022
Deformable plate tectonic models have been demonstrated to be a useful technique for quantifying temporal variations in strain rate and crustal thickness within recent plate kinematic studies.

Crustal thickness variations in northern Morocco [PDF]

Journal of Geophysical Research: Solid Earth, 2012
During the TopoIberia experiment, a total of 26 seismic broadband stations were recording in northern Morocco, providing for the first time extended regional coverage for investigating structure and seismotectonics of the southern branch of the Betic‐Rif arc, its foreland, and the Atlas domain.

The crustal thickness of West Antarctica [PDF]

Journal of Geophysical Research: Solid Earth, 2014
P‐to‐S receiver functions (PRFs) from the Polar Earth Observing Network (POLENET) GPS and seismic leg of POLENET spanning West Antarctica and the Transantarctic Mountains deployment of seismographic stations provide new estimates of crustal thickness across West Antarctica, including the West Antarctic Rift System (WARS), Marie Byrd Land (MBL) dome ...

Gravity‐Derived Antarctic Crustal Thickness Based on the Gauss‐FFT Method

Geochemistry, Geophysics, Geosystems, 2022
The information on crustal thickness in Antarctica can provide significant constraints on its crustal deformation and tectonic evolution. To generate reliable images of crustal features, we investigate the model of Moho depth and crustal thickness ...
