Th-U-Pb DATING OF THE GOLD-BEARING ROCKS ARE SIMILAR TO CARBONATITES OF THE KARABASH ULTRABASIC MASSIF (SOUTHERN URALS)
The gold-bearing rocks are similar to carbonatites were dated. They located on the Golden Mount, near the town of Karabash, Southern Urals. Monazite and thorianite are found in the gold-bearing rocks are similar to carbonatites and were analyzed on a microprobe. The age was calculated based on chemical Th-U-total Pb data. The two mineral isochrones yield an age of 317,3±3,0 Ma. Education the gold-bearing rocks are similar to carbonatites of the Karabash massif occurred in the Lower Devonian and transformation - in the Upper Carboniferous.
