Summary: The natural pressure data supports the lithostatic assumption, contradicting the excessive overpressure theory proposed by Bauville and Yamato. The selection and preservation of rocks play a crucial role in influencing pressure data from (U)HP rocks.

Summary: The research data suggests that the location and shape of the Pamir plateau may be caused by the forceful indentation of the Indian mantle lithosphere, resulting in complex interactions with the Asian slab. The Indian mantle indenter may lead to the delamination and overturning of the Asian slab, while also affecting the lithosphere of the Tarim basin.

Summary: Geophysical and rheological studies have shown that elevated pore fluid pressures may facilitate slow slip and tremor in subduction zones. This study examines the deformation mechanisms within metamorphic rocks to understand how these pressures affect seismic activity. The results highlight the importance of understanding the role of pore fluid pressure in earthquake generation.

Summary: Three types of eclogites were identified in the Xiaoxinzhuang area in the northern Sulu ultrahigh pressure (UHP) terrene. They exhibit different mineral compositions, characteristics, and distribution patterns. The rocks underwent UHP metamorphism, revealing a unique pressure-temperature path compared to other areas in the Sulu UHP terrane.

Summary: The mechanisms of burial and exhumation of crustal material during the Alpine orogeny are debated. New mechanical models suggest deviations from lithostatic pressure as a possible mechanism for forming high-pressure rocks. Through petrological, geochronological, and structural data, the relationship between pressure and depth in metamorphic rocks is assessed, challenging traditional depth measurement methods.

Summary: The eclogites from the Guanshan and Yangkou areas of the Sulu orogen are composed of garnet, omphacite, phengite, amphibole, quartz/coesite, rutile, and ilmenite. The mineral assemblages and phase equilibria modeling indicate two stages of metamorphism: prograde associated with quick subduction and retrograde associated with quick exhumation. These stages are consistent with the regional metamorphic events with ages of 245, 227, and 195 Ma.

Summary: The study reveals that interactions between plates in opposite-dip double subduction-collision systems can affect the process of continental-margin crustal exhumation, potentially preventing UHP metamorphic rocks from reaching the Earth's surface. The speed and modes of crustal subduction and rock exhumation vary in different types of models.

Summary: This study reports on Archean ultrahigh-pressure peridotites in North China, providing direct evidence for the operation of continental collisional plate tectonics since at least 2.5 billion years ago. The peridotites are believed to be tectonic slivers of a collisional complex that were subducted to mantle depths and then exhumed to crustal levels during Neoarchean subduction and subsequent arc/continental collision.

Summary: This study collected ultrahigh-pressure eclogites with coesite inclusions from the northern Dulan terrane in the North Qaidam orogen. Through zircon U-Pb dating and pressure-temperature calculations, it was found that these eclogites represent a continuous record from oceanic subduction to continental collision.

Summary: This study provides evidence for the key role of paleo-trench sediments in constraining the continental crust recycling as well as the origin and compositional heterogeneity of arc igneous rocks above ancient oceanic subduction zones.

Summary: Refertilization of fertile garnet lherzolites occurs during peak-UHP metamorphic stages in a continental subduction channel, as shown by the presence of abundant clinopyroxene and garnet, low Mg# and high Al2O3. The metasomatic agents for refertilization are likely basaltic-intermediate melts incorporating continental materials.

Summary: The North China Craton (NCC) is a highly active tectonic region with scattered late Cenozoic volcanism and small-scale low-velocity anomalies in the upper mantle. Previously proposed plate boundary processes cannot explain the observed asthenospheric upwellings in the NCC. This study suggests that edge-driven convection caused by large changes in lithospheric thickness is likely the major cause of NCC's upper mantle structure and late Cenozoic volcanism.

Summary: A study on metamorphic rocks in the Western Alps reveals evidence of fluid metasomatism during continental subduction, with indication of magmatic origin and potential sourcing from the mantle wedge. This has significant implications for tracing geochemical processes of previous oceanic subduction.

Summary: The study uses seismic and gravity modeling to reveal the crustal structure of the Sulu Orogenic Belt (SLOB), including the distribution of ultrahigh/high-pressure metamorphism in the southern SLOB and crustal deformation in the northern SLOB. The results suggest that the spatial distribution of orogenic belts in the SLOB is wider than previously thought, with implications for understanding collision belts in other geological regions.

Summary: In this work, a new adaptive multiresolution method is presented for solving the Stokes problems of highly viscous materials in computational geodynamics. The method utilizes a particle-in-cell approach on a static Eulerian finite element grid, with material properties carried by Lagrangian material points. The Eulerian grid is adapted using a wavelet-based adaptation algorithm. The proposed method supports both bilinear and biquadratic mixed approximations for the Stokes system. It has been successfully applied to various benchmark problems and shows excellent agreement with non-adaptive simulations and analytical solutions, while significantly reducing computational requirements in terms of time and memory usage.
