The Matachewan Large Igneous Province (LIP) is interpreted to have formed during mantle plume-induced continental break-up during the early Proterozoic. When the Matachewan LIP is reconstructed to its original configuration, the dyke... more

Rare minerals, chloriane amphiboles and chloriane biotites were discovered in rocks of Palaeoproterozoic (Jatulian) traps of Karelia: in gabbro-dolerites of layered Kojkarsko-Svjatnavolok sill and in coarse-grained albitic (“karjalitic”)... more

In continental-margin subduction zones, basalt magmas spawned in the mantle interact with the crust to produce a broad spectrum of volcanic arc associations. A distinct style of very voluminous arc volcanism develops far inland on thick... more
