Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective contributions remain unconstrained.

The Influence of the Shape of Graphite Precipitates on the Cast Iron Abrasion Resistance

, 2019
The paper presents the initial results of investigation concerning the abrasion resistance of cast iron with nodular, vermicular, or flake graphite. The nodular and vermicular cast iron specimens were cut out of test coupons of the IIb type with the wall

Geochemical and petrographic re‐evaluation of ungrouped iron meteorites from Western Australia

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 444-465, March 2026.
Abstract Under the current classification scheme, ungrouped irons make up ~11% of all recognized iron meteorites. A further ~7% of iron meteorites are currently classified as simply “irons” and are yet to be fully classified. To potentially classify these meteorites, newer approaches, including either statistical modeling or advanced geochemical ...

Computer Simulation of the Structure Formed During Solidification of Cast Iron

, 1984
By combining heat extraction laws with kinetic growth laws, the solidification process of nodular, grey and white cast iron have been calculated. The risk for formation of white structure during solidification of grey and nodular cast iron was calculated.

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, Volume 41, Issue 2, Page 260-287, February 2026.
ABSTRACT The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...
