GEOCHRONOLOGY OF ULTRAMAFIC LAMPROPHYRE DIKES IN THE TOMTOR COMPLEX
This work studies thin ultramafic lamprophyre (UML) dikes associated with the Tomtor alkaline-ultramafic massif (Arctic Siberia). 40Ar/39Ar dating yielded an emplacement age of 710 Ma for the dikes. U-Pb dating of calcite indicates a 400 Ma year old low-temperature recrystallization event. Both age...
