Tectonics, Volume 41, Issue 12, December 2022., 2022 Abstract Orogenic wedges are common at convergent plate margins and deform internally to maintain a self‐similar geometry during growth. New structural mapping and thermochronometry data illustrate that the eastern Greater Caucasus mountain range of western Asia undergoes deformation via distinct mechanisms that correspond with contrasting lithologies ...

Adsorption Science & Technology, 2022 The North Qilian orogenic belt is a typical area of “cold” subduction of the early Paleozoic oceanic plate, forming a series of high pressure and low temperature metamorphic rock assemblages. Among them, eclogite is a kind of protolith, which is basaltic

A continuum theory for mineral solid solutions undergoing chemo-mechanical processes [PDF]
, 2021 Recent studies on metamorphic petrology as well as microstructural observations suggest the influence of mechanical effects upon chemically active metamorphic minerals. Thus, the understanding of such a coupling is crucial to describe the dynamics of geomaterials.

A Log‐Ratio‐Based Algorithm for Petrologic Mass‐Balance Problems and Uncertainty Assessment
Geochemistry, Geophysics, Geosystems, 2023 We provide a new algorithm for mass‐balance calculations in petrology and geochemistry based on the log‐ratio approach championed initially by John Aitchison (e.g., Aitchison, 1982, https://doi.org/10.1111/j.2517-6161.1982.tb01195.x; Aitchison, 1984 ...

Известия Томского политехнического университета: Инжиниринг георесурсов, 2021 The relevance of the work is caused by weakly elaboration of mineralogical aspects of ultramafic restitic massifs, which does not allow their generalization at mineralogical level and restoration of complete history of their formation and transformation,

The Reflectance Spectra of CV-CK Carbonaceous chondrites from the Near Infrared to the Visible [PDF]
, 2021 Carbonaceous chondrite meteorites are so far the only available samples representing carbon-rich asteroids and in order to allow future comparison with samples returned by missions such as Hayabusa 2 and OSIRIS-Rex, is important to understand their physical properties.

Journal of Metamorphic Geology, Volume 41, Issue 1, Page 25-57, January 2023., 2023 Abstract The Variscan high‐grade metamorphic basement of northern Sardinia and southern Corsica record lower Carboniferous anatexis related to post‐collisional decompression of the orogen. Migmatites exposed in the Punta Bianca locality (Italy) consist of quartz + biotite + plagioclase + K‐feldspar orthogneisses, garnet and cordierite‐bearing diatexite

Evolution of the parent body of enstatite (EL) chondrites [PDF]
, 2021 Chondrites stem from undifferentiated asteroidal parent bodies that nevertheless experienced a certain degree of metamorphism after their formation in the early solar system. Maximum temperatures of metamorphism depend mainly on formation time and the abundance of the main heating source, which is short-lived 26Al.
