Laser ablation(in situ)Lu-Hf dating of magmatic fluorite and hydrothermal fluorite-bearing veins被引量:3
《Geoscience Frontiers》2023年第6期142-154,共13页Stijn Glorie Jacob Mulder Martin Hand Adrian Fabris Alexander Simpson Sarah Gilbert 
supported by research grants DP200101881 and FT210100906 from the Australian Research Council(ARC)and additionally;the Mineral Exploration Cooperative Research Centre.
Fluorite(CaF_(2))is a common hydrothermal mineral,which precipitates from fluorine-rich fluids with an exceptional capacity to transport metals and Rare Earth Elements(REEs).Hence,the ability to date fluorite has impo...

Deciphering the presence of axial-planar veins in tectonites
《Geoscience Frontiers》2019年第6期2101-2115,共15页Elena Druguet 
Thanks to Jordi Carreras for giving insightful advice during article preparation and to Claudio Rosenberg for sharing his picture in Fig.13e.I am also particularly grateful to two anonymous reviewers for very constructive reviews that have greatly improved the paper
Veins and dikes are often oriented subparallel to the axial surfaces of folds in the adjacent layered or foliated rocks.This implies an awkward situation,since veins would lay in planes close-to-parallel to the maximu...
