Primary crustal melt compositions: Insights into the controls, mechanisms and timing of generation from kinetics experiments and melt inclusions [PDF]

, 2017
We explore the controls, mechanisms and timing of generation of primary melts and their compositions, and show that the novel studies of melt inclusions in migmatites can provide important insights into the processes of crustal anatexis of a particular ...

Timing of Mylonitization Based on Zircon U–Pb Ages of the Ryoke Plutonic Rocks in the Akaiwadani and Taraki Areas, Eastern Kii Peninsula, Southwest Japan: Implications for Uplifting of a Late Cretaceous Volcanic Arc on the Asian Continental Margin

Island Arc, Volume 34, Issue 1, January/December 2025.
ABSTRACT The timing of mylonitization of the Ryoke Plutonic Rocks in the Tsukide area, eastern Kii Peninsula, Southwest Japan, which is part of a Late Cretaceous volcanic arc on the Asian continental margin, was investigated based on geological relationships and zircon U–Pb dating.

Rare alkali metals in micas from Shakhdarinskaya miarolitic pegmatite (South-Western Pamir)

Известия Томского политехнического университета: Инжиниринг георесурсов, 2017
The study is focused on the mineralogy of rare-element rich tourmaline-bearing miarolitic pegmatities of the Shakhdarinskaya vein (SW Pamirs, Tajikistan). The results of the study are crucially important for understanding the regularities of distribution and behavior of Li, Rb and Cs in the course of crystallization of the most low-temperature ...

Hydrous shear zones are sites of melt transfer in the lower arc crust: A case study from Fiordland, New Zealand

Journal of Metamorphic Geology, Volume 42, Issue 7, Page 933-956, September 2024.
Abstract Recent studies of the Cretaceous lower arc crust exposed in Fiordland, New Zealand, conclude that shear zones are sites of melt migration and mass transfer through the deep crust. Here, we investigate the 4–10 km‐wide George Sound Shear Zone, which cuts the Western Fiordland Orthogneiss, comprising two main rock types: two‐pyroxene gneiss and ...

Middle to Late Ordovician flare‐up of granitoids, South Altyn Tagh: Reworking of exhumed continental crust

Geological Journal, Volume 59, Issue 8, Page 2190-2207, August 2024.
U–Pb ages, and O–Hf isotopic compositions of inherited and synmagmatic zircons are addressed to trace the source rocks and petrogenesis of a monzogranite pluton, which belong to the flare‐up of granitoids at 465–445 Ma in the South Altyn Tagh. The observations indicate that this monzogranite is mainly derived from reworking of exhumed continental crust,

Turbidity in alkali feldspars from granitic pegmatites

, 1994
Alkali feldspars from pegmatite of Brazil and Spain have microscopic to submicroscopic inclusions giving a >turbid> and >clouded> appearance. Inclusions are isotropic, irregular and spatially associated with patch/vein lamellae in network and/Or isolated masses. Inclusions have no detectable lines in XRD and microprobe analyses show strong variability:
