Potential and costs of carbon dioxide removal by enhanced weathering of rocks
Environmental Research Letters, 2018 The chemical weathering of rocks currently absorbs about 1.1 Gt CO _2 a ^−1 being mainly stored as bicarbonate in the ocean. An enhancement of this slow natural process could remove substantial amounts of CO _2 from the atmosphere, aiming to offset some ...

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 ...

Origin of magmatic harzburgite as a result of boninite magma evolution - An illustration using layered harzburgite-dunite cumulate from the Troodos ophiolite complex [PDF]
, 2020 Olivine (Ol) and orthopyroxene (Opx) are the primary liquidus phases of boninite in modern subduction settings and in many ophiolite complexes. It is thus straightforward to expect the formation of harzburgite cumulate resulting from boninite magma ...

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Experimental deformation of an «anhydrous » synthetic dunite
Bulletin de Minéralogie, 1979 Une série d'expériences à vitesse de déformation constante a été conduite sur une dunite synthétique pour des températures de 1100° à 1300° C et à 15 kbar de pression hydrostatique. Les échantillons sont ici plus résistants que ceux de toutes les expériences antérieures, sauf celles de Post.

Ball Milling Effect on the CO2 Uptake of Mafic and Ultramafic Rocks: A Review
Geosciences, 2018 Mineral carbonation is considered to be the most stable mechanism for the sequestration of CO2. This study comprises a comparative review of the effect of ball milling on the CO2 uptake of ultramafic/mafic lithologies, which are the most promising rocks ...
