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.

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]
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 ...

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

Magmatic Intrusions Control Io's Crustal Thickness [PDF]
Journal of Geophysical Research: Planets, 2020 AbstractIo, the most volcanically active body in the solar system, loses heat through eruptions of hot lava. Heat is supplied by tidal dissipation and is thought to be transferred through the mantle by magmatic segregation, a mode of transport that sets it apart from convecting terrestrial planets.

地震科学进展, 2021 In this study，we used high signal-to-noise ratio teleseismic wave form data with an epicenter 30°—90° and the magnitude above 5.5 （including 5.5） of Xiangfan seismic station recorded during 2015—2018 to calculate the receiver functions using the time ...

Inverting Rayleigh surface wave velocities for crustal thickness in eastern Tibet and the western Yangtze craton based on deep learning neural networks [PDF]
Nonlinear Processes in Geophysics, 2019 Crustal thickness is an important factor affecting lithospheric structure and deep geodynamics. In this paper, a deep learning neural network based on a stacked sparse auto-encoder is proposed for the inversion of crustal thickness in eastern Tibet and ...

CRUSTAL THICKNESS VARIATIONS AND SEISMICITY OF NORTHWESTERN SOUTH AMERICA
Earth Sciences Research Journal, 2007 Any uncompensated mass of the northern Andes Mountains is presumably under pressure to adjust within the Earth to its ideal state of isostatic equilibrium. Isostasy is the ideal state that any<br />uncompensated mass seeks to achieve in time. These

Crustal thicknesses in Fennoscandia [PDF]
Geophysical Journal International, 1980 b As a supplement to seismic profiling surveys, crustal thicknesses have been estimated for 11 Fennoscandian seismograph stations equipped with three-component long period instruments, using the so-called spectral ratio technique of Phinney. The largest Moho depths, of the order of 45 km, were found for stations located in the north-east areas ...

Crustal structure beneath the central and western North China from receiver function analysis
Earthquake Science, 2022 The North China Craton (NCC) is one of the oldest cratons on earth. Several important tectonic transformations of Mesozoic-Cenozoic tectonic regime led to the destruction of the North China craton. The knowledge of crustal structure can provide important
