Review in Zirconology. I. Progress in U-Pb dating of zircon.

JOURNAL OF MINERALOGY, PETROLOGY AND ECONOMIC GEOLOGY, 1993
In this paper (Part I), recent progress in U-Pb dating of zircon is reviewed. Rare-earth element (REE) partitioning of accessory minerals and REE geochemistry of zircon will be reviewed in separate papers, Part II and Part III, respectively. Zircon (ZrSiO4) is one of the most important minerals in geochronology because the zircon crystal is very ...

Discordance dating: A new approach for dating alteration events [PDF]

Geochronology
Zircon is the premier geochronometer used to date igneous and metamorphic processes, constrain sediment provenance models, and monitor key events in Earth history such as the growth of continents and the evolution of the biosphere.

Zircon U-Pb Dating, Geochemical Characteristics of the Fangjidao Granitic Rocks in the Southeasternmost Cathaysia Block and Their Tectonic Implications

, 2021
Early Paleozoic granites are widely distributed in the Fangjidao area, the western Guangdong province, i.e., the southeastern Cathaysia Block. They experienced intensive shearing zone deformation and metamorphism, and now occur as mylonized granitic ...

Provenance and tectonic setting of Paleogene sandstone in the center of the northern Qaidam Basin, China

Journal of Natural Gas Geoscience, 2020
The average thickness of Paleogene sandstones reaches about 3000 m or even 4000 m at the northern margin of the Qaidam Basin. However, the provenance of these sandstones has been uncertain; thus, more comprehensive research is needed. Integrated research
