, 2021 The cratonic lithosphere–asthenosphere boundary is commonly invoked as the site of sheared peridotite and megacryst formation, a well-recognized petrologic assemblage whose genetic relationships – if any – remain poorly understood. We have undertaken a

Dizhen xuebao, 2021 2010年智利马乌莱MW8.8地震发生在纳斯卡板块与南美板块的板块边界处，引起了显著的同震和震后效应。GPS台网数据显示记录到的同震海向位移最大约5 m，垂向沉降最大约50 cm。在经过对俯冲效应、季节变化等效应的校正后，震后6年的海向最大位移约68 cm，垂向抬升最大约20 cm。马乌莱地震显著的震后形变对该区域的地下三维黏弹性结构有良好的约束。本文建立了智利中南部俯冲带区域的三维有限元模型，黏弹性的地幔楔及海洋地幔均使用伯格斯体材料，并在断层面上设置2 km厚的软弱层以模拟震后余滑 ...

Geochemistry, Geophysics, Geosystems, 2020 The oceanic lithosphere is a primary component of the plate tectonic system, yet its evolution and its asthenospheric interaction have rarely been quantified by in situ imaging at slow spreading systems.

Rifts, orogens, cratons, and global tectonics: Introduction
Геодинамика и тектонофизика, 2017 A key role in developing the Earth theory is played by comparative studies of orogens, rifts, and platforms in the equatorial, middle and high latitudes of Asia and the adjacent Arctic regions.

Space Weather, 2020 During magnetic storms, solar‐magnetosphere‐ionosphere‐Earth interactions give rise to geomagnetically induced currents (GICs) in man‐made technological conductors such as power grids, gas pipelines, and railway networks with potentially damaging ...

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.

Post-collisional Tertiary–Quaternary mafic alkalic magmatism in the Carpathian–Pannonian region: a review [PDF]
, 2004 Mafic alkalic volcanism was widespread in the Carpathian–Pannonian region (CPR) between 11 and 0.2 Ma. It followed the Miocene continental collision of the Alcapa and Tisia blocks with the European plate, as subduction-related calc-alkaline magmatism was

Structure and dynamics of the oceanic lithosphere-asthenosphere system
Physics of the Earth and Planetary Interiors, 2020 The thermochemical evolution of oceanic lithosphere and its interaction with the underlying asthenosphere exerts a fundamental control on the dynamics of the Earth system.

Geochemistry, Geophysics, Geosystems, 2023 Rapid plate motion, alongside pronounced variations in age and thickness of the Australian continental lithosphere, makes it an excellent location to assess the relationship between seismic anisotropy and lithosphere‐asthenosphere dynamics. In this study,
