Experimental Study of the Effect of Different Influencing Factors on the Interaction of CO₂, Water, and Basalt

Energies
Basalt has been studied in recent years as a novel geological medium for CO2 sequestration, thus enriching and expanding the carbon sink potential of geological bodies. In this study, four sets of CO2–water–basalt interaction experiments were carried out

Forming Olivine Phenocrysts in Basalt: A 3D Characterization of Growth Rates in Laboratory Experiments

Frontiers in Earth Science, 2019
Our current knowledge of the genesis, ascent, storage, and eruption of mafic magmas is intimately linked with olivine, its primary crystal cargo. Recent claims that phenocryst-size crystals can grow rapidly and non-concentrically are challenging our ...

The Paleoenvironment of the Ndutu Bed at Olduvai Gorge in the Context of Middle Stone Age Expansion in Eastern Africa: A Multiproxy Approach to Ungulate Analyses From the Victoria Cabrera Site and Dorothy Garrod Site (MIS 5)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The study of the Eastern African archaeological record is essential for understanding the origin and evolution of the Middle Stone Age (MSA). However, Olduvai Gorge, one of the primary regions in human evolution studies, has few sites associated with the MSA.

Modified basalt material reinforced organic coatings: A review

Corrosion Communications
Natural basalt can be processed into rod-like basalt fibers (BFs) and flake-like basalt scales (BSs) through high-temperature melting, forming and other processes. BFs and BSs have great application prospects in the field of organic coatings. BFs possess

Experimental Comparative Analysis of Hole‐Making Strategies and Cutting Parameters on Flexural Properties and Induced Delamination in S2 Glass and Basalt Fiber‐Reinforced Polymers

Polymer Composites, EarlyView.
Hole‐making strategy and machining parameters influence delamination and hole quality in S2‐glass and basalt FRP composites, which subsequently affet flexural performance. Improved hole integrity leads to enhanced structural performance during three‐point bending.
