The dual role of fracturing and elevation on the development of the weathering profile in mafic landscapes of the Andean tropics

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Eighteen boreholes in Colombia's Tropical Andes reveal elevation‐controlled Critical Zone architecture. Four‐layer weathering profiles with thick saprolite (≤48 m) form at high elevations (>1,100 m) where dense fracturing enhances permeability. Low‐elevation boreholes lack saprolite despite high fracture density, demonstrating fracturing's dual role as

Trace element composition of silicate minerals from Kunashak Meteorite (L6)

Записки Горного института
Major (EPMA) and trace (SIMS) element geochemistry in the silicate minerals (olivine, pyroxene and plagioclase) of Kunashak equilibrated ordinary chondrite (L6) is described. No variations in the major element concentrations of the silicate minerals have

The Neolithic Site of Piano dei Cardoni in the Island of Ustica (Italy): Minero‐Petrographic and Chemical Characterization of the Ceramic Finds and Clayey Raw Materials

Geoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments

Hydrological Processes, Volume 40, Issue 3, March 2026.
Conceptual diagram of hydrological and geochemical processes within the Santa Elena Ophiolite, Costa Rica. It highlights watershed cross‐sections, soil genesis, hyperalkaline Type II waters (pH > 11.6) with calcite crust and trapped H2/CH4 gases, seepage into surface waters, storm‐impacted stream profiles, weathered vs.

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.
