Some volcanologic aspects of Columbia River basalt volcanism relevant to the extinction controversy [PDF]
The Columbia River Basalt Group is the youngest and most thoroughly studied flood-basalt province known; information about it should be relevant to questions about the possible relation of flood-basalt volcanism to mass extinctions. The group has a total

Frictional Instabilities and Carbonation of Basalts Triggered by Injection of Pressurized H2O- and CO2- Rich Fluids [PDF]
, 2018 The safe application of geological carbon storage depends also on the seismic hazard associated with fluid injection. In this regard, we performed friction experiments using a rotary shear apparatus on precut basalts with variable degree of hydrothermal ...

The geology and geochronology of Al Wahbah maar crater, Harrat Kishb, Saudi Arabia [PDF]
, 2014 Al Wahbah is a large (∼2.2 km diameter, ∼250 m deep) maar crater in the Harrat Kishb volcanic field in western Saudi Arabia. It cuts Proterozoic basement rocks and two Quaternary basanite lava flows, and is rimmed with an eroded tuff ring of debris from ...

Modified basalt material reinforced organic coatings: A review
Corrosion CommunicationsNatural 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
