Petrogenesis of Eocene Lamprophyre Dykes in Northern Qiangtang Terrane, Tibetan Plateau: Implications for the Tethyan Mantle Metasomatism and Tectonic Evolution
Published 2023-10-01“…We propose that the Cenozoic ultrapotassic mafic rocks in the central Tibetan Plateau originated in the lithospheric mantle metasomatized by the subduction-related components, and are the magmatic response to the detachment of the subducted Tethyan slab.…”

A review of the geodynamic setting of the Volcanic Domain in the Juruena Magmatic Arc, southwestern Amazon Craton, Brazil, based on geochemical, U-Pb and Sm-Nd data
Published 2019-04-01“…The continental arc interpretation for the VD is supported by the following lines of evidence: (1) spatial arrangement of the VD in the shape of a volcanic belt; (2) the large volume of volcaniclastic deposits and related epizonal granitic intrusions; (3) variable chemical signatures ranging from subalkaline mafic compositions to high-K calc-alkaline, A-type oxidized granites, showing REE and trace element patterns similar to those of subcontinental lithospheric mantle sources enriched by subduction-zone fluids, and subordinate involvement of continental crust; (4) crystallization and Sm-Nd TDM model ages, respectively, ranging between 1820 and 1780 Ma, and from 2.40 to 1.84 Ga, with eNd(t) values of -3.9 to +2.5, yielding an overlap in U-Pb and Sm-Nd ages of rocks from the Juruena Magmatic Arc; (5) the occurrence of epithermal-porphyry Au systems in the Alta Floresta Gold Province with ages compatible with those of the VD magmatic period.…”

The Palermo (Sicily) seismic cluster of September 2002, in the seismotectonic framework of the Tyrrhenian Sea-Sicily border area
Published 2004-06-01“…The events of the easternmost zone may be related to the Ionian lithospheric slab diving beneath the Calabrian Arc. The seismicity associated with the westernmost zone is closely clustered around a sub-horizontal regression plane contained within the thinned Southern Tyrrhenian crust, hence suggesting that this seismogenic zone is strictly connected to the deformation field active within the hinge zone. …”

Petrogenesis and Tectonic Implications of the Early Cretaceous Granitic Pluton in the Sulu Orogenic Belt: The Caochang Granitic Pluton as an Example
Published 2020-05-01“…Integrating the findings of this study and previous work, we propose that the Caochang granitic pluton is derived from the partial melting of the deep Yangtze basaltic lower crust during the Early Cretaceous, and that the large-scale thinning of the lithospheric mantle was the main factor that led to Early Cretaceous magmatic flare-up in the Sulu orogenic belt.…”

Published 2022-08-01“…Differing from rhyolite and dacite, basaltic andesite shows a relatively young age (234 ± 1.2 Ma), mainly originating from the partial melting of the lithospheric mantle modified by subducted slab-derived fluids; the magma was contaminated with a small amount of crustal source components and experienced the fractional crystallization of mafic minerals before the eruption to the surface. …”
