The Edel'veis alkaline intrusive complex, Gorny Altai: a plume-related derivative of the early paleozoic magmatism in Central Asia
The <sup>40</sup>Ar/<sup>39</sup>Ar isotope age (506,8±3,5 MA) was determined for alkaline rocks of the Edel'veis carbonatite-bearing Complex in Gorny Altai. Its formation is related to the origin of a large igneous province during the Caledonian epoch of the Central Asian folded belt evolution. This alkaline intrusion is regarded as a result of the activity of mantle super-plume that initiated different magmatism of Central Asia in the Early and Middle Palaeozoic.
