    The Mesoarchean Tonalite-Trondhjemite-Granodiorite Associations of Eastern Sarmatia: Age and Geological Setting

    Two episodes of Mesoarchean magmatism (ca. 2.95 and 3.03 Ga) have been recognized within the Kursk domain of Eastern Sarmatia. They led to the formation of the Saltyki granitoid complex, which is similar in co...
