TTGs (tonalite–trondhjemite–granodiorite) are one of the archetypical lithologies of
Archaean cratons. Since their original description in the 1970s, they have been the subject …

A specific type of granitoid, referred to as sanukitoid (Shirey & Hanson 1984), was emplaced
mainly across the Archaean–Proterozoic transition. The major and trace element …

We investigate the relationship between sulfur and oxygen fugacity at Erta Ale and Masaya
volcanoes. Oxygen fugacity was assessed utilizing Fe3+/∑ Fe and major element …

A common feature of the mineralised chonolith intrusions of the Norilsk-Talnakh camp is the
presence of globular disseminated Ni–Cu–Fe sulphide ores, particularly well developed …

Volcanism in lceland appears to have been confined to volcanic systems throughout its
history. During Late-Pleistocene and Holocene times some 41 volcanic systems have been …

The computer-based modeling of geological and geophysical data allows the construction of
3D geological models that can predict the location of differing lithologies, intrusive units and …

The Holocene eruption history of subglacial volcanoes in Iceland is largely recorded by their
tephra deposits. The numerous basaltic tephra offer the possibility to make the …

Recent volcanic products from the Piton de la Fournaise Volcano, Reunion, show
pronounced depletion or enrichment in lithium and significant isotopic fractionation related …

Phonolite and trachyte are the felsic magmas of the alkaline magma suites, which
characterize the Canary Islands. The October 2011 submarine eruption off El Hierro, the …

For the last two decades, Iceland and other oceanic plateaux have been considered as
potential analogues for the formation of the early Earth's continental crust. This study …
