Изотопное датирование ультракалиевого магматизма Центральной Чукотки: Rb-Sr возраст и геохимические особенности монционитов линкор
Title: | Изотопное датирование ультракалиевого магматизма Центральной Чукотки: Rb-Sr возраст и геохимические особенности монционитов линкор |
Title, transliterated: | Izotopnoe datirovanie ulʹtrakalievogo magmatizma T︠S︡entralʹnoĭ Chukotki: Rb-Sr vozrast i geokhimicheskie osobennosti mont︠s︡ionitov linkor / S.V. Efremov, and 3 others. |
Translated title: | Isotope dating of ultrapotassic magmatism in central Chukotka: Rb-Sr age and geochemistry of monzonites from the Linkor stock. |
Author(s): | Efremov, S. V. |
Date: | 2008. |
Language: | Russian. |
In: | Geologii︠a︡ i Geofizika. (2008.), Vol. 49(4) (2008) |
Abstract: | Presents results of isotope dating of ultrapotassic magmatism in central Chukotka. Estimates time of one stage of ultrapotassic magmatism to be 107-113 Ma, based on Rb-Sr isochron age on monzoites from Linkor stock (107± 2.2 Ma) and using previously obtained geochronological isotope data. Results permit reconstruction of geological history of region. |
