Origin of the Azubai Be-mineralized pegmatites, Xinjiang Altay: constraints from Li–Hf isotopes
Open GeosciencesThe genetic mechanism of rare-metal pegmatites – whether they form primarily by extreme fractionation of granitic magmas or direct crustal anatexis – remains highly controversial.

Compositional evolution of tourmaline in granitic pegmatites
, 1999 Tourmaline is the most common B-bearing mineral in rare-element granitic pegmatites. The extensive substitutions in its crystal structure, which relate directly to the composition of the host rock, makes it a useful petrological and geochemical indicator

Quartz chemistry in polygeneration Sveconorwegian pegmatites, Froland, Norway
, 2008 Element concentrations in quartz, feldspar and biotite of Sveconorwegian (1.13-0.9 Ga) granitic pegmatites in Froland, Norway, were analysed by LA-lCP-MS, EPMA and XRF, respectively, in order to determine chemical variations between different pegmatite ...

Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: 207Pb-206Pb dating of magnetite, monazite and allanite in the central and northern Nagssugtoqidian orogen, West Greenland [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2006 Pb-isotopic data for magnetite from amphibolites in the Nagssugtoqidian orogen, central West Greenland, have been used to trace their source characteristics and the timing of metamorphism. Analyses of the magnetite define a Pb-Pb isochron age of 1726 ± 7
