Abstract
The first isotope-geochronological studies of rocks from Matua Island (Central Kuril Islands) are presented. These rocks, found at the base of the Neopleistocene-Holocene volcanic edifice, belong to the earliest stages of magmatic activity. Based on K–Ar dating, 9 age values ranging from 3.9 to 1.02 million years were obtained for rocks from the Yurlovskaya and Dvoynaya formations. The Yurlovskaya suite was formed within the age range from the Middle Pliocene to the Gelasian (3.9±0.3–2.02±0.13 million years ago), while the Dvoynaya suite was formed during the Gelasian Age (2.09±0.14 million years ago). The formation of the extrusive dome of Mount Kruglaya and the subvolcanic body of Skala Krepost' (Ainu Bay) occurred 1.02±0.13 and 1.08±0.15 million years ago, respectively.
