Hydrothermal alteration of magmatic titanite: Implications for REE remobilization and the formation of ion-adsorption HREE deposits, South China

American Mineralogist, 2023
Ion-adsorption rare earth element (REE) deposits in South China are currently the main source of heavy rare earth elements (HREE). The Gucheng deposit in western Guangdong Province is one example of HREE mineralization hosted in weathered coarse-grained ...

Titanite geochemistry and textures: Implications for magmatic and post-magmatic processes in the Notch Peak and Little Cottonwood granitic intrusions, Utah

American Mineralogist, 2022
Textural and compositional variations in titanite constrain the roles of magma mixing and hydrothermal alteration in two plutons in central Utah: the Jurassic Notch Peak and the Oligocene Little Cottonwood stocks.

EPMA geochemistry and LA-ICPMS dating of allanite, epidote, monazite, florencite and titanite from the Jaduguda uranium deposit, Singhbhum Shear Zone, eastern India: Implications for REE mineralization vis-à-vis tectonothermal events in the Proterozoic Mobile Belt

Precambrian Research, 2021
The Singhbhum shear zone (SSZ), eastern India, located close to the boundary between the Proterozoic North Singhbhum Mobile Belt and the Archaean Singhbhum craton, is the best known uranium province and one of the most important copper districts in India.

How faithfully do the geochronological and geochemical signatures of detrital zircon, titanite, rutile and monazite record magmatic and metamorphic events? A case study from the Himalaya and Tibet

Earth-Science Reviews, 2020
Detrital geochronology, generally focused on zircon only, is widely used not only to obtain qualitative information on source areas but also in quantitative provenance analysis aimed at calculating sediment yields and erosion rates under the assumption ...

Elemental and Nd isotopic compositions of zoned titanite in mafic microgranular enclaves of the Early Cretaceous Sanguliu granitic pluton in the North China Craton: Insights into magma mixing process

Lithos, 2021
Widespread Mesozoic granitic plutons in the North China Craton (NCC) are products of remelting of the crust associated with large-scale Mesozoic destruction of the NCC. Mafic microgranular enclaves (MMEs) are common in these plutons and are attributed to

Hydrothermal titanite U–Pb age and geochemistry as a reliable chronometer and genetic tracer for quartz vein-type tungsten deposit at Qipangou of Qinling orogenic belt, Central China

, 2021
Although quartz vein-type deposits are extremely common worldwide, their formation age is difficult to determine due to the lack of suitable minerals for precise isotope dating.

The role of titanite in shaping the geochemistry of amphibolite-derived melts

Lithos, 2021
Titanite, one of the major accessory phases in middle to lower crustal rocks, could play an important role in shaping trace element as well as radiogenic isotope compositions in amphibolite-derived melts. Petrographic, zircon U/Pb, whole-rock element and

Reworked early Precambrian basement of the Dunhuang Block (NW China) as revealed by titanite U–Pb dating

, 2021
The Dunhuang Block in the Central Asian Orogenic Belt (CAOB) consists of Archean to Paleoproterozoic crystalline basement, along with Paleozoic complexes that are related to the evolution of the CAOB. A current main controversy concerns whether the whole

Trace elements in titanite: A potential tool to constrain polygenetic growth processes and timing

Chemical Geology, 2019
The petrological information preserved in the trace element signature of titanite is a valuable complement to in situ U/Pb geochronology, and can be used to refine interpretations on the growth of this mineral.
