Terra Nova, Volume 38, Issue 2, Page 97-105, April 2026.ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

The Dehydration of Serpentines and Extraction of Water
The Planetary Science JournalSome groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,

Geological Journal, Volume 61, Issue 3, Page 566-592, March 2026.Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

New Zealand's Second Meteorite: Makarewa (find, L4, S5, W2)
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.One of the most remarkable discoveries of a meteorite in New Zealand was that of Makarewa. Discovered in 1879, Makarewa is a ‘find’ that was uncovered a metre below the surface of a clay bank during excavation works for a train line in the southern South Island.

Chiral Symmetry Breaking in Gelation
Small Structures, Volume 7, Issue 3, March 2026.Although chiral symmetry breaking in gelation is usually regarded as a rare phenomenon, this might not be true. Rather, recent studies suggest that its probability to emerge in gelation can be higher than that in crystallization, indicating the presence of rich science to be uncovered in the corresponding research fields.

Carbonated Chondrites during Giant Impacts
The Planetary Science JournalThe volatile budget of terrestrial planets is primarily inherited from the accretion process. At this stage, impacts played a significant role in delivering or removing volatiles from the silicate of young planets.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The role of sub‐arc mantle lithosphere in the build‐up of a batholith is an outstanding issue that is still not well resolved. Lamproite is a mantle‐derived magmatic rock that provides a window to learn the composition and the enrichment processes of subcontinental lithospheric mantle (SCLM).

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract It is recognized that mantle plumes play a direct role in generating regional uplift and producing immense volumes of basaltic magmatism, both of which can influence paleoclimate. The Icelandic Plume, beneath the North Atlantic Ocean, is of particular importance due to its size and position at a significant paleoceanographic gateway.
