The Cambrian Metavolcanic Rocks of the Upper Unit of the Maksyutov Complex (South Urals): Results of U–Pb (SHRIMP II) Dating of Zircon

Key Points

The research aims to date the zircon in metavolcanic rocks to understand their geological history.
Utilized U–Pb SHRIMP II dating technique on zircon samples.
Analyzed zircon from the upper structural-compositional unit of the Maksyutov complex.
Identified three age groups of zircon from the samples.
Found ancient Early Proterozoic zircon dating back to 2060 ± 22 Ma, indicating xenogenic origins.
Identified Early Cambrian zircon at 517 ± 7 Ma linked to oceanic basalt crystallization.
Discovered Early Devonian zircon at 411 ± 5 Ma reflecting progressive metamorphism at 395–418°C.

Abstract

New results of zircon study (U–Pb method, SHRIMP II) from metavolcanic rocks of the upper structural-compositional unit of the Maksyutov complex, Sakmara River, the area of settlement of Novotroitsky, are presented. It is established that zircon from metavolcanic rocks forms three age groups. Ancient Early Proterozoic (2060 ± 22 Ma) continental-type zircon is xenogenic. Igneous Early Cambrian (517 ± 7 Ma) zircon registers the crystallization of oceanic basalt. Metamorphic Early Devonian (411 ± 5 Ma) zircon reflects progressive metamorphism at a temperature of 395–418°C.
