Chemical Heterogeneities along the South Atlantic Mid-Ocean-Ridge (5-11°S): Shallow or Deep Recycling of Ocean Crust? [PDF]
, 2011 Between 5° and 11°S, the Mid-Atlantic Ridge displays anomalous crustal thickness and geochemical compositions, thought to be related to either small scale upper mantle heterogeneities or a weak, diffuse mantle plume.

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 349-364, March 2026.Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

Steric Effects of Alkyl Ammonium Salts on the Combustion of Exchanged Smectite Clays [PDF]
, 2018 Bomb calorimetry was explored as a new method for determining the cation exchange capacity (CEC) of clays. Smectite clays were modified with several alkyl ammonium salts varying in number of carbons and the spatial orientation of the carbons about the ...

The Depositional Record, Volume 12, Issue 1, February 2026.Sediments, unlithified and lithified microbial mats in the Salar de Atacama, are formed by similar pathways involving coupled precipitation of authigenic Mg silicate and calcium carbonate. Differences in products reflect differences in the initial distribution of organic biomass.

The Depositional Record, Volume 12, Issue 1, February 2026.The deep paleo‐lake, characterised by low energy and moderate salinity, facilitated the input of fine‐grained minerals and the development of aquatic organic matter. Under the combined influence of the sedimentary environment and material source, mineral‐bound organic matter was formed, which played a crucial role in the enrichment of organic matter ...

Badlands and environmental change [PDF]
Geographica HelveticaBadlands develop in many climatic regions, on a wide range of soils and in various bedrock types. The physical triggers for development of badlands can be natural, such are tectonic activity and climate change, but more frequently they are human induced,
