The fact that mineral deposit attributes such as the size frequency of orogenic gold deposits
in specific provinces exhibit power law distributions similar to forest fires, earthquakes, and …

The lower plate is the dominant agent in modern convergent margins characterized by
active subduction, as negatively buoyant oceanic lithosphere sinks into the asthenosphere …

New mineral deposit discoveries are required to meet the forecasted demand for some
critical raw materials. Governments are responding to that challenge by investing in mineral …

We present a comprehensive petrographic, mineralogical and geochemical study of calc-
alkaline lamprophyres (CAL) from the Archean Yilgarn Craton, Western Australia. Previous …

Evidence for episodic crustal growth extending back to the Hadean has recently prompted a
number of numerically based geodynamic models that incorporate cyclic changes from …

During the Archean, episodic volcanism commonly included both plume-and arc-type
magmatism, raising the issue of a possible link between “bottom up” and “top down” …

New studies in the central and southern parts of the Murchison Domain in the Youanmi
Terrane, western Yilgarn Craton, reveal previously unidentified igneous rock types in …

Mantle xenoliths from Zarnitsa pipe studied in gray eruptive breccias (early) brown autholitic
breccia (BAB) and black macrocrystic kimberlites (last dike; BMK), include garnet and spinel …

The alkaline igneous rocks of the Chompolo field (Aldan shield, Siberian craton), previously
defined as kimberlites or lamproites, are more correctly classified as low-Ti lamprophyres …

Abstract The Archean Superior craton was formed by the assemblage of continental and
oceanic terranes at∼ 2.6 Ga. The craton is surrounded by multiple Proterozoic mobile belts …
