PEROVSKITE FROM SPURRITE-MERWINITE MARBLES OF THE KOCHUMDEK CONTACT AUREOLE: APPLICATION TO U-Pb DATING OF A THERMAL EVENT

PEROVSKITE FROM SPURRITE-MERWINITE MARBLES OF THE KOCHUMDEK CONTACT AUREOLE: APPLICATION TO U-Pb DATING OF A THERMAL EVENT

The paper presents the results of the first LA-ICP-MS U-Pb geochronological studies of 60 perovskite grains from spurrite marbles of the Kochumdek contact aureole (East Siberia). Perovskite is a dominant accessory mineral of U- and Th-poor marbles, which formed at the contact with traps of the Kuz’m...
