40Ar/39Ar DATING OF ALKALINE ROCKS FROM THE BURPALA MASSIF AS A KEY TO UNDERSTANDING ITS FORMATION DURATION
https://doi.org/10.5800/GT-2025-16-5-0849
Abstract
The article presents the results of 40Ar/39Ar dating of rocks (quartz and alkali syenites, nepheline syenites with REE-Nb-Zr mineralization) from the Burpala massif using feldspar, phlogopite, and amphibole. The obtained results limit the closure of the K-Ar isotope system in feldspars of quartz and alkali syenites to 274–283 Ma, while the age of closure of the K-Ar isotope system in amphibole of alkali syenite and in phlogopite of ore-bearing nepheline syenite is 298±4 Ma and 301±4 Ma, respectively. Estimates of the formation pressure using the plagioclase–hornblende geobarometer show that the massif rocks were formed at a depth of about 10 km. Comparison with zircon age values indicates a simultaneous closure of the U-Pb and K-Ar isotope systems in zircons, phlogopite and amphibole, respectively. The closure of the K-Ar isotope system in feldspars occurred 12–15 million years later.
