UDC (553.411’43’481.044:552.1):551.71/.72(571.51/.52+571.53) ON THE PROBLEM OF ORE-BEAING GREENSTONE BELTS IN THE EASTERN SAYAN PROVINCE
A. N. Smagin, V. P. Parnachev
Relicts of Early-Precambrian greenstone belts in the Kansk, Biryusinsk, Sharyzhalgaisk and other Eastern Sayan tectonic protrusions are characterized. New data on the structure and minerogenesis of the Herma-Kakhtarma protrusion in the Agul, Maly-Tagul and Gutara-Tumanshet troughs are provided. The lastmentioned troughs contain abundant ultramafic bodies having sulfide mineralization and united in the structure of the Kakhtarma and Agul-Tumanshet potentially ore-bearing areas (POA). The positive assessment of gold mineralization of the Omuch-Ulchsky gold-ore cluster localized in the Archean and Lower-Proterozoic greenstone belt sequences in the Gutara-Tumanshet trough is given.
Key words: Early Precambrian, greenstone belt, sulphide copper-nickel mineralization, gold mineralization, Eastern Sayan Mountains.
