Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]

, 2006
Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

The Neolithic Site of Piano dei Cardoni in the Island of Ustica (Italy): Minero‐Petrographic and Chemical Characterization of the Ceramic Finds and Clayey Raw Materials

Geoarchaeology, Volume 41, Issue 2, March/April 2026.
ABSTRACT This paper presents the results of minero‐petrographic and chemical analyses of pottery and potential local raw materials from Ustica, a small volcanic island off the coast of Palermo (Sicily), inhabited during the Middle Neolithic. Typologically, the pottery shows cultural connections to the Bicromica and Serra d'Alto traditions, linking ...

Two-sided asymmetric subduction; implications for tectonomagmatic and metallogenic evolution of the Lut Block, Eastern Iran [PDF]

, 2011
West directed subduction zones show common characteristics, such as low structural elevation, deep trench, steep slab and a conjugate back-arc basin that are opposite to those of the east directed subduction zones.

Surface reactivity of amphibole asbestos. A comparison between crocidolite and tremolite [PDF]

, 2017
Among asbestos minerals, fibrous riebeckite (crocidolite) and tremolite share the amphibole structure but largely differ in terms of their iron content and oxidation state. In asbestos toxicology, iron-generated free radicals are largely held as one of

Amphibole's Influence on Mid‐Lithosphere Discontinuity: Insights From Electrical Conductivity

Geophysical Research Letters
The potential role of metasomatism‐induced hydrated layers, such as amphibole, in causing the mid‐lithospheric discontinuities (MLDs) has been widely debated.

Mineralogy, mineral chemistry and thermobarometry of post-mineralization dykes of the Sungun Cu–Mo porphyry deposit (Northwest Iran)

Open Geosciences, 2020
The Sungun copper–molybdenum porphyry deposit is located in the north of Varzaghan, northwestern Iran. The Sungun quartz-monzonite is the oldest mineralized intrusive body in the region and was emplaced during the Early Miocene.

METASOMATIC AND MAGMATIC PROCESSES IN THE MANTLE LITHOSPHERE OF THE BIREKTE TERRAIN OF THE SIBERIAN CRATON AND THEIR EFFECT ON THE LITHOSPHERE EVOLUTION

Геодинамика и тектонофизика, 2015
The area of studies covers the north-eastern part of the Siberian craton (the Birekte terrain), Russia. The influence of metasomatic and magmatic processes on the mantle lithosphere is studied based on results of analyses of phlogopite- and phlogopite ...

High P‐T Sound Velocities of Amphiboles: Implications for Low‐Velocity Anomalies in Metasomatized Upper Mantle

Geophysical Research Letters
Metasomatized mantle xenoliths containing hydrous minerals, such as amphiboles, serpentine, and phlogopite, likely represent the potential mineralogical compositions of the metasomatized upper mantle, where low seismic velocities are commonly observed ...
