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.

Origin of the Azubai Be-mineralized pegmatites, Xinjiang Altay: constraints from Li–Hf isotopes

Open Geosciences
The genetic mechanism of rare-metal pegmatites – whether they form primarily by extreme fractionation of granitic magmas or direct crustal anatexis – remains highly controversial.
