Glaciochemical investigations of the ice deposit of Vukušić Ice Cave, Velebit Mountain, Croatia
The 3H activity and the concentration of 23 metals and metalloids have been analysed in cave ice samples from the perennial cave ice deposit of Vukušić Ice Cave, Velebit Mt., Croatia. The results of tritium measurements exclude a secular age for the upper 2.4 m of ice deposition, and provide clear a...
