Mineralogical Asbestos Assessment in the Southern Apennines (Italy): A Review
Fibers, 2019 This paper deals with petrography and mineralogy of serpentinitic rocks occurring in the Southern Apennines (Italy) with the aim to review the already available literature data and furnish new details on asbestos minerals present in the studied area. Two

Banded skarns, an example of geochemical dissipative structure [PDF]
, 1993 20 pages (texte), 6 pages (eight figures and one table)Banded skarns are metasomatic rocks produced by oscillatory precipitation on a centimetre scale. These rocks result from the transformation of homogeneous carbonate materials by aqueous fluids under ...

Mount Etna as a Leaking Pipe of Magmas From the Low Velocity Zone
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Mount Etna, one of the most active volcanoes on Earth, exhibits unusual characteristics in terms of its geological setting, effusion rate, and volatile content. Mount Etna is closely related to the subduction of the Ionian plate below Eurasia, but, chemically, Mount Etna lavas are akin to intraplate magmatism.

Testing Models for Upper Mantle Earthquakes in the Tanganyika‐Rukwa Rift, Africa
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Rifts that initiate in mechanically strong, stable continental lithosphere are characterized by M > 5 earthquakes at depths >35 km near or below the crust mantle interface. Current models for deep rift zone earthquakes invoke elevated pore pressures associated with magmatism, and rapid stressing from magma intrusions.

Eclogitic metatrondhjemites from metaophiolites of the Western Alps [PDF]
, 2016 In the Urtier valley (southern Aosta Valley, Italy), the Piemonte metaophiolites mainly consist of serpentinized peridotites including pods and boudinaged layers of Fe-metagabbro and trondhjemite transposed in the main eclogitic foliation.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Comprehension of the ophiolitic mélange plays a key role in the tectonic reconstruction of an ancient orogenic belt in terms of plate tectonics. The tectonic nature of the NNW‐trending southern Jinshajiang ophiolitic mélange is still controversial.

Mineralogical characterization of Sn deposits from the Santa Fe District, Bolivia [PDF]
, 2015 The Sn-Zn-Pb-Ag Japo-Santa Fe-Morococala ore deposit is located in the Central Andean Belt province. The ore mineralization is hosted in a Paleozoic metasedimentary sequence and porphyritic Oligocene-Miocene igneous rocks. Ore minerals occur in veins and

Geochemistry of Precordillera serpentinites, western Argentina : evidence for multistage hydrothermal alteration and tectonic implications for the Neoproterozoic-early Paleozoic [PDF]
, 2015 Serpentinites are a powerful tool to evaluate mantle composition and subsequent alteration processes during their tectonic emplacement. Exposures of this type of rocks can be found in the Argentine Precordillera (Cuyania terrane) and Frontal Cordillera ...
