UDC (551.332.214:551.79)(571.51) AUREOLE OF ORE BOULDERS AT THE TALNAKHSKO-OKTYABRSKOYE DEPOSIT AND THE ENVIRONMENT OF THEIR FORMATION
More than 40 years it was doubtful that the aureole of ore boulders at the Talnakhsko-Oktyabrskoye deposit was a result of the movement of the mountain-valley Upper Quaternary Zyryansky glacier in the Norilsk region. But in 2001, V.G. Chuvardinsky suggested that the boulders have a tectonic nature. The paper describes characteristic features of composition and structure of typical glacial and interglacial Middle and Late Quaternary deposits. A typical moraine of the Samara (Q2 2sm), Taz (Q2 2tz), and Zyryanka (Q2 3zr) glaciations contains loamy clay, sandy clay, and clay with large boulders present. Analysis of maximum (Samara) glaciation evidences is of great importance in study of boulder transport by a glacier in the Norilsk region. The data provided in the paper suggest that large granite boulders were actually transported by glaciers from Taymyr to the Central Siberian Plateau during the Middle Quaternary.
Key words: Taymyr, Samara glaciation, Zyryanka glaciation, Sartan glaciation, boulder loamy clay, granite boulders, limestone boulders, Wenlockian fauna.
