Abrasivity database of different genetic rocks based on CERCHAR Abrasivity Test

Scientific Data
Rock abrasivity is one of the main factors affecting the wear of rock-cutting tools, which is usually quantified by the CERCHAR Abrasivity Index (CAI). Researchers and engineers study tool wear and predict tool life based on the CAI of rocks.

Ductile Extrusion Triggered by Continental Collision in NE Brazil

Terra Nova, EarlyView.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Fugitive Junctures: Life‐Seeking, Route‐Finding and the Mobile Ensemble at Kenya's Borders

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract Fugitivity has become an important conceptual frame to understand the illegalised mobilities of contemporary migrants in conjunction with enslaved people's historical lines of flight as spatial praxes to seize their own freedom. Thinking from Kenya, and drawing on research with migrants, border officials, activists, police and smugglers,

An archean suture zone in the Tobacco Root Mountains? (1984) Evolution of Archean Continental Crust, SW Montana (1985) [PDF]

The Lake Plateau area of the Beartooth Mountains, Montana were mapped and geochemically sampled. The allochthonous nature of the Stillwater Complex was interpreted as a Cordilleran-style continental margin.
