Description

Rb-Sr isochrone corresponding to 2.12+-0.10 m.y. with the initial Sr isotopic ratio of 0.70690+-7, MSWD=0.6. The isochrone is dating the final magmatic stage in the history of the Eldjurta granite. The corroboration of the previous isotopic geochronology data indicated in particular that the more ancient age of Spider plagiogranites is disturbed by excess argon. Refs. 18, figs. 3
