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

Quantifying crustal thickness over time in magmatic arcs [PDF]

Scientific Reports, 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 ...

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 ...

The crustal thickness of Australia [PDF]

Journal of Geophysical Research: Solid Earth, 2000
We investigate the crustal structure of the Australian continent using the temporary broadband stations of the Skippy and Kimba projects and permanent broadband stations. We isolate near‐receiver information, in the form of crustal P‐to‐S conversions, using the receiver function technique.

Geological Implications of Crustal Thickness, Vp/Vs, and Poisson's Ratio Beneath the Western Mesopotamian Plain Edge, Iraq

Iraqi Geological Journal, 2023
To know the crustal structure, composition, deformation, and evolution, it is crucial to appreciate the ratio between the velocity of the primary wave and the velocity of the secondary wave, Poisson's ratio, and crustal thickness.

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 ...

Crustal Structure beneath the Precambrian Cratons of Gondwanaland and Its Evolution Using Teleseismic Receiver Function

Lithosphere, 2022
The Gondwana supercontinent was an accretion of several cratons from different landmasses, namely South America, Antarctica, Africa, Madagascar, Australia, and the Indian subcontinent.

Record of Crustal Thickening and Synconvergent Extension from the Dajiamang Tso Rift, Southern Tibet

Geosciences, 2021
North-trending rifts throughout south-central Tibet provide an opportunity to study the dynamics of synconvergent extension in contractional orogenic belts.

Spatial and Temporal Variations in Crustal Structure in the Eurasian Basin

Journal of Marine Science and Engineering, 2022
To understand the tectonic–magmatic history, crustal structure and crustal accretion mode of the Eurasian Basin in the Arctic, we calculated the crustal thickness, residual bathymetry (RB) and non-isostatic topography of the Eurasian Basin by using the ...
