Characteristics and Geodynamic Evolution of Indosinian Granitoids in South China: A Case Study in the Guangdong Province

Geosciences
The Indosinian granitoids of Guangdong Province, South China, record a complex history of crust–mantle interactions during the Triassic assembly of the South China Block (SCB) and Indochina Block (ICB). Integrated zircon U–Pb geochronology, geochemistry,

H2O-fluxed remelting of arc roots drives continent maturation and the Daly Gap

Nature Communications
Granitic plutons are key components of the continental crust, resulting from the interplay between fractional crystallization (FC) of mantle melts and crustal anatexis.

Fluorapatite from a Pegmatite with Miarolitic Cavities in the Larsemann Hills, East Antarctica: ID-TIMS U-Pb Ages and LA-ICP-MS Trace-Element Constraints on the Late Pan-African Orogenic Evolution

Geosciences
Pegmatites with miarolitic cavities have not previously been reported from the Larsemann Hills, East Antarctica, and their age and origin remain poorly constrained.

Zircon and allanite U-Pb ID-TIMS ages of vaugnerites from the Calzadilla pluton, Salamanca (Spain): dating mantle-derived magmatism and post-magmatic subsolidus overprint

Geologica Acta, 2017
Basic to intermediate high-K, high-Mg mantle-derived rocks occur throughout the Iberian Massif and are particularly important in the Tormes Dome, where vaugnerites form several stocks and small plutons. One of the largest and geochemically most variable

Melting of fluorine-rich biotite as a mechanism for generating lithium-rich granites

Communications Earth & Environment
Granitic melts derived from anatexis of metasedimentary rocks, particularly biotite-dehydration reactions, are important lithium (Li) sources. Petrogenetic models depend on mineral-melt lithium partitioning, yet published partition coefficients ( $${D}_{{
