Coexistence of calc-alkaline and ultrapotassic alkaline magmas at Mounts Cimini : evidence for transition from the Tuscan to the Roman Magmatic Provinces (central Italy) [PDF]
, 2011 The volcanic complex of Mts. Cimini (~0.90-1.30Ma) represents the geographical and chronological transition between the Tuscan Magmatic Province (TMP) and the Roman Magmatic Province (RMP), in central Italy.

Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]
, 2006 During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The role of sub‐arc mantle lithosphere in the build‐up of a batholith is an outstanding issue that is still not well resolved. Lamproite is a mantle‐derived magmatic rock that provides a window to learn the composition and the enrichment processes of subcontinental lithospheric mantle (SCLM).

Геодинамика и тектонофизика, 2017 In large igneous provinces (LIP) of fold areas, granitoid rocks are dominant, while mantle-derivated rocks play a subordinate role in rock formation. If magma emissions are impulsive, it may take 25–30 million years for a LIP to form and take shape.

Enhancement of lamproite magnetic signatures
ASEG Extended Abstracts, 2009 Lamproites are peralkaline, typically ultrapotassic (6 to 8% K2O) and magnesia-rich lamprophyric rocks of volcanic or hypabyssal origin and are now considered to crystallize from a distinct type of magma. Most lamproites occur in irregular, asymmetric craters that are generally rather shallow, usually less than 300 metres in depth, often in the shape ...

The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]
, 2011 In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

Mantle-to-crust metal transfer by nanomelts [PDF]
, 2023 The transfer of chalcophile metals across the continental lithosphere has been traditionally modeled based on their chemical equilibrium partitioning in sulfide liquids and silicate magmas.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract The mid‐Norwegian Margin, part of the North Atlantic Igneous Province (NAIP), is a well‐studied volcanic rifted margin formed during the breakup between Greenland and Eurasia ∼56 Ma, with the largest accumulation of magmatic material hosted by the Vøring Margin section.
