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.

Mineralization and geochemical studies in the Kalchouyeh occurrence, southwest of Naein

Journal of Economic Geology, 2012
Kalchouyeh area in southwest of Naein is located in the Urumieh-Dokhtar volcano-plutonic belt. Mineralization occurred mainly as disseminations and veinlets hosted by trachy-andesite and pyroxene andesites. For mineralogy, alteration, fluid inclusion and

Epithermal Beam Development at the BMRR: Dosimetric Evaluation

, 1990
The utilization of an epithermal-neutron beam for neutron capture therapy (NCT) is desirable because of the increased tissue penetration relative to a thermal-neutron beam. Over the past few years, modifications have been and continue to be made at the Brookhaven Medical Research Reactor (BMRR) to produce an optimal epithermal beam by changing filter ...

[Epithermal neutron capture therapy] [PDF]

, 1993
Development of a 4 mA, 2.5 MeV Tandem Cascade Accelerator (TCA) for the production of neutrons via the [sup 7]Li(p,n)[sup 7]Be nuclear reaction is currently nearing completion at SRL. The TCA is a tandem electrostatic accelerator which uses a high current negative ion source in conjunction with a high current solid state cascade multiplier power supply

Early cretaceous molybdenum-bearing felsic magmatic rocks in the tongmushan district, northern great Xing’an range: implications for mesozoic porphyry metallogenesis

Frontiers in Earth Science
The Nenjiang-Heihe metallogenic belt of the northern Great Xing’an Range is renowned for Mesozoic epithermal Au deposits, however, apart from the Duobaoshan and Tongshan super-large porphyry deposits in the Paleozoic, no superlarge porphyry copper ...

Nuclear Data Uncertainty Quantification for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors [PDF]

EPJ Web of Conferences
The use of the F-19 isotope in the nuclear fuel cycle is already well established for fuel enrichment, but future plans for Gen-IV reactors, such as Molten Salt Reactors, could utilize a fluorine-based salt as a basis for the fuel.
