The Tasiast gold deposits are hosted within Mesoarchean rocks of the Aoueouat greenstone belt, Mauritania. The Tasiast Mine consists of two deposits hosted within distinctly different rock types, both situated within the hanging wall of the west-verg

The thermal structure of Archean terranes depends in part on the thermal transport properties of their distinctive rock types. We determined thermal diffusivity ( D ) of a suite of 14 greenstone, mafic granulite and tonalite–trondhjemite–granodio

One barrier to quality in Bible translation is a tendency for translators to translate literally from their primary source text. This is a hazard for any translator, but has particular relevance in the case of Mother-Tongue Translators (MTTs) with mi

A geochronological study of the Kapuskasing structural zone (KSZ), a section of Late Archean lower crust within the southern Superior Province, Canadian Shield, was undertaken to test a plate tectonic model for the Late Archean Abitibi‐Opatica terr

The anisotropy of magnetic susceptibility (AMS) is widely and routinely used to measure the preferred orientations of Fe-rich minerals in undeformed and weakly deformed granite plutons. The interpretation of the mapped AMS fabrics depends on rock-tex

This work investigates the structures of the Abitibi granite-greenstone belt, Ontario, with a focus on regional-scale folds and on regional-scale auriferous fault zones. The folds and the fault zones resulted from Late Archean orogenesis. The analysi

Anisotropy of magnetic susceptibility and structural geology of the ca. 1.45 Ga Karlshamn pluton (southern Sweden) are used to study its emplacement and structural evolution. The Karlshamn pluton is one of the largest metaluminous A-type granitoid in

The Sudbury impact structure is one of the few multi-ring meteorite impact structures recognized on Earth. The meteorite impact occurred ca. 1850 Ma, resulting in the production of impact melts derived from the crust, possibly with a mantle component

The Abitibi belt is one of the largest and most extensively studied Late Archean greenstone belts. The structural geology of the Abitibi belt consists of one generation of upright to slightly overturned, doubly plunging first-order folds with half-wa

We relate families of faults in the Ottawa graben to periods in the tectonic evolution of eastern North America. The Ottawa graben is a seismically active structure that coincides with a 55 km wide topographic depression extending from near Montreal
