Detritic Zircons from the Archean Quartzites of the Matlakhta Greenstone Belt of the Karelian Craton: Hydrothermal Alterations,Mineral Inclusions, and Isotope Age

摘要

Zircon, which is one of the most universal minerals applicable to geochronometry, is an important source of information about the age of rocks and superimposed processes. The special role of ancient detritic zircons in the reconstruction of the earliest Hadean processes of formation and transformation of the Earth's continental crust was established. As it turned out, in detritic zircons selected from the Paleoprotero-zoic quartz arenites and conglomerates in the area of the Jack Hills, a range of hills in Western Australia, there was recorded information about the earliest hydrothermal processes in the Hadean time.
