Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 506-538, June 2026.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

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.

Chromitite genesis based on chrome-spinels and their inclusions in the Sartohay podiform chromitites in west Junggar of northwest China

Ore Geology Reviews, 2020
Abstract Primary high-Al [Cr# = 100 × Cr/(Cr + Al) of 48.2–54.7] chromitites coupled with high-Cr (Cr# = 70.9–80.7) chromitite fragments are identified in the podiform chromitites hosted by the Sartohay ophiolitic melange in west Junggar, northwest China.

Dike Swarms in the Oceanic Lithosphere Beneath the Ontong Java Plateau

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract The Ontong Java Plateau (OJP) is believed to have formed through large‐scale Cretaceous volcanism, but the impact of the massive volcanism on the lithosphere remains largely unknown. In this study, the ascent process of the thermochemical plume and its impact on the physicochemical properties of the pre‐existing lithosphere were explored. High‐

Interpretation of magnetic and geoelectrical data based on geological and mineralogical evidence in the podiform chromite prospecting, Khoy ophiolite, Northwest Iran

Journal of Economic Geology, 2021
Introduction Podiform chromite deposits are small magmatic chromite bodies formed in the lower section of an ophiolite complex. The Khoy ophiolite covers an extensive area in the northwest of Iran along the Iran-Turkey border.

Magnetotellurics Point to Serpentinization as a Potential Source of Hydrogen in the Bulqizë Ophiolite

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Hydrogen was first detected in the Bulqizë ophiolite massif (Albania) in 1992, and its origin remains uncertain, with hypotheses ranging from active serpentinization to the release of trapped, fossil H2. To constrain the thickness of the ophiolite layer—a key parameter for evaluating hydrogen generation—we conducted a magnetotelluric survey ...
