Geochemical and petrological insights into the tectonic origin of the Transmexican Volcanic Belt
Abstract The Transmexican Volcanic Belt (TMVB) is the magmatic expression of one of the
most complex convergent margins on the planet, and as such constitutes a prime location for …

Strongly SiO2-undersaturated, CaO-rich kamafugitic Pleistocene magmatism in Central Italy (San Venanzo volcanic complex) and the role of shallow depth limestone …
Abstract The Pleistocene (~ 460–265 ka) San Venanzo volcanic complex belongs to the IAP

Identifying mantle carbonatite metasomatism through Os–Sr–Mg isotopes in Tibetan ultrapotassic rocks
Mantle-derived magmas at convergent plate boundaries provide unique insights into the
nature of materials subducted to and recycled from depths. Here we present a study of Os …

Evolution of K-rich magmas derived from a net veined lithospheric mantle in an ongoing extensional setting: Geochronology and geochemistry of Eocene and …
Abstract The Eocene and Miocene volcanic rocks between the cities of Trabzon and Giresun
in the Eastern Pontides (NE Turkey) erupted as mildly and moderately alkaline magmas …

Recycled carbonate‐bearing silicate sediments in the sources of circum‐Mediterranean K‐rich lavas: Evidence from Mg‐Zn isotopic decoupling
The high flux of subaerial volcanic CO2 emissions around the circum‐Mediterranean region
requires the involvement of an unusually carbon‐rich reservoir, but the origin of which is still …

An experimental study of the role of partial melts of sediments versus mantle melts in the sources of potassic magmatism
Potassium-rich lavas with K/Na of> 2 are common in orogenic and anorogenic intraplate
magmatic provinces. However, in the primitive mantle, the concentration of Na exceeds that …

Ultrapotassic magmatism in the heyday of the Variscan Orogeny: the story of the Třebíč Pluton, the largest durbachitic body in the Bohemian Massif
The Třebíč Pluton (TP) comprises plutonic rocks of the 'durbachite series', ie, ultrapotassic

Calcium isotope compositions of subduction-related leucite-bearing rocks: Implications for the calcium isotope heterogeneity of the mantle and carbonate recycling in …
Large Ca isotope variations recorded in mantle xenoliths and mantle-derived igneous rocks
have been widely used to decode the origin of mantle heterogeneity, especially to trace …

Quartz-bearing rhyolitic melts in the Earth's mantle
The occurrence of rhyolite melts in the mantle has been predicted by high pressure-high
temperature experiments but never observed in nature. Here we report natural quartz …

Melting and dynamic metasomatism of mixed harzburgite+ glimmerite mantle source: Implications for the genesis of orogenic potassic magmas
Tectonically young, orogenic settings are commonly the sites of post-collisional silica-rich
ultrapotassic magmas with extreme K 2 O-contents of up to 9 wt% and K 2 O/Na 2 O> 2 …
