Magnetic properties of ilmenite‐hematite single crystals from the Ecstall pluton near Prince Rupert, British Columbia [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2011
Paleomagnetic studies of the 91 Ma Ecstall pluton and other Cretaceous plutons of British Columbia imply large northward tectonic movements (>2000 km) may have occurred during the tectonic evolution of western North America.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Internal framework and geochemistry of the Carboniferous Huaco granite pluton, Sierra de Velasco, NW Argentina [PDF]

open access: yes, 2018
The A-type Huaco granite pluton of the Velasco range (Sierras Pampeanas of northwest Argentina) is formed by three coeval granitic facies and contains subordinate coeval-to-late facies, as well as enclaves, dikes and stocks that show different temporal ...

Wind Turbine’s Aerodynamic Multiplication Parameters for Different Types of Generators [PDF]

open access: yesProblems of the Regional Energetics
Energy transition is impossible without wind power development. The need for a mechanical multiplier to match the speeds of a wind turbine and generator leads to deterioration of the tech-nical system's indicators.

Ranking the geothermal potential of radiothermal granites in Scotland: are any others as hot as the Cairngorms? [PDF]

open access: yes, 2017
Prior investigations concur that the granite plutons in Scotland which are most likely to prove favourable for geothermal exploration are the Ballater, Bennachie, Cairngorm and Mount Battock plutons, all of which have heat production values greater than ...

Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

open access: yes, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.
