Summary: The tectono-metamorphic evolution of the European Alps, specifically the Monte Rosa tectonic unit, is still debatable, with peak pressure and temperature estimates varying significantly between different lithologies. Petrological studies in the western portion of the Monte Rosa nappe revealed staurolite-chloritoid-bearing metapelitic assemblages indicating lower peak pressure estimates than previously reported for whiteschist lithologies. The region shows structural coherence, suggesting that the higher pressure in whiteschist lenses may be due to dynamic pressure rather than tectonic slices.

Summary: The study of accessory REE- and Ti-bearing minerals in rocks of the northern part of the West Ny Friesland anticlinorium, Svalbard Archipelago revealed distinct assemblages corresponding to different stages of metamorphic history, with earlier REE-bearing minerals transitioning into rutile and Fe-Ti oxide assemblages in the late stages of porphyroblast growth. The phase reactions controlling accessory mineral formation were discussed in terms of temperature and pressure conditions.

Summary: This study investigates the mineral composition differences and metamorphic evolution processes of eclogite and related metabasites from the south-eastern flank of the Pohorje Mountains in Slovenia. The results reveal two metamorphic stages, with the formation of nearly Cr-free garnet under high-pressure conditions in the first stage, and the growth of Cr-bearing garnet in the second stage.

Summary: This study conducted isotope analyses on two ocean island basalt (OIB)-associated enriched mafic intrusions in the Yunnan-Burma region, and found that these rocks may have originated from the subduction recycling of marine sediments and altered oceanic crust.

Summary: This study provides important petrologic information on the mantle wedge above an active subduction zone in Southern Colombia. The researchers analyzed a unique suite of rock samples and found evidence of hydration, metasomatism, and partial melting in the mantle wedge. They also observed variations in lithotypes, textures, and mineral abundance, indicating different interactions with melts and fluids. This study sheds light on the complex petrological processes occurring in the mantle wedge and contributes to our understanding of subduction zone dynamics.

Summary: The Hogenakkal complex in India consists of silicate-rich and silicate-poor carbonatites and clinopyroxenites. The formation of carbonatite is influenced by silicate minerals. The carbohydrothermal mineralization in the carbonatites is induced by magma-derived fluids and interactions with the surrounding rocks.

Summary: The role of collisional belts in the global carbon budget is controversial. This study reveals a previously unrecognized carbon source in the collisional orogen of the Himalayas, where metamorphism of carbonate-bearing rocks in the hanging wall resulted in significant CO2 degassing.

Summary: This study investigates the zircon ages and whole-rock geochemical data of Late Paleozoic magmatic rocks in the Western Yunnan Tethyan belt to identify the origin and mechanism of mantle melting. The results suggest that these magmatic rocks may originate from different mantle domains that were metasomatized by slab-derived fluids and sediment-derived melts.
