Subaqueous high-silica rhyolite in Prosser Township, southern Abitibi Subprovince, Ontario, consists of intercalated, thin ( Mass balance calculations and textural analysis demonstrate that the high-silica aphyric rhyolites were originally glassy hav

Spinifex-textured sills (i.e., veins) characterized by komatiitic magmas that have intruded their own volcanic-piles have long been recognized. For instance, in the early 1970s, Pyke and coworkers, in their classic work at Pyke Hill in Munro Township

Fragmental rocks of the V10 units of the Vipond Formation of the Tisdale assemblage previously have been identified as pillow basalts, but many samples are shown to be intermediate-to-felsic in character, likely tholeiitic dacite in composition. Spec

The Wavelet Transform was used to analyze the evolutionary record of planktic foraminifera to distinguish specific structure not previously resolvable. Both the speciation and extinction wavelets are characterized by a major singularity at the Cretac

The Sudbury structure, Ontario, is the remnant of a 1.85 Ga old impact crater, which originally had a diameter of 200 to 250 km. The Sudbury Igneous Complex occurs within the Sudbury structure. The Sudbury Igneous Complex is a 2.5- to 3.0-km-thick, ~

Many intriguing crystallization textures of Archaean volcanic rocks are ‘supercool’ in the sense that they are visually striking, and because they owe their origin to substantial undercooling of the silicate liquids from which they grew. Under co

The Holloway mine, a mesothermal gold deposit, is located within the western Abitibi subprovince, Ontario. Mineralized zones that contain microscopic gold within pyrite are hosted by a sequence of metakomatiites, mafic to felsic metavolcanic, and met
