Abstract

New K-Ar ages combined with paleomagnetic data demonstrate that the basaltic volcanism in the Perşani Mountains occurred in two relatively short phases. The first one lasted several tens of thousands of years around 1.2 Ma and it seems that the inception of the volcanic activity took place in two isolated places and reached the maximum extent during the Cobb Mountain Normal Polarity Subchron when larger areas were covered. The second phase started just before 600 ka and was restricted to the central area of the volcanic field. One lava flow of this phase recorded a short-lived reversed polarity event inside the Brunhes Normal Chron, probably the 15Β reversal excursion. The duration of this phase was less than 200 kyr, which is the best estimate according to the available radiometric data.
