Resumo

There are several large intrusions composed of 70–75% leucogranites within Eastern Kazakhstan. Information on the age of the intrusions is provided, the features of the composition of the rocks are considered, and conclusions about the petrogenetic mechanisms of forming of leucogranite magmas are drawn. Two stages of leucogranite intrusive magmatism have been established – in the Early Permian and in the Early Triassic. Their formation occurred in an intraplate geodynamic setting. Leucogranite magmas were formed as a result of partial melting of crustal substrates under the thermal influence of mafic magmas. Geochemical differences in leucogranites were due to different compositions of crustal substrates and different degrees of their melting.

2. Fig. 1. The layout of leucogranite intrusions in Eastern Kazakhstan. It is based on the scheme of magmatic complexes of Eastern Kazakhstan [11]. 1 – sedimentary and volcanogenic formations (S–C), undifferentiated; 2 – basite-ultrabasite intrusions (C1, P1); 3 – continental basalts and andesites (C2-P1); 4 – granitoid intrusions (C1–2); 5 – granitoid intrusions (P1); 6 – leukogranite intrusions (P1, T1); 7 – swarms of basal dikes (C2-P1); 8 – faults; 9 – Quaternary deposits. The numbers in the circles are leucogranite intrusions, in the Kalba–Narym zone: 1 - Dungalinsky massif, 2 – Monastyrsky massif, 3 – Sibinsky massif, 4 – Voylochevsky massif; in the Charsky zone: 5 – Semeytau massif, 6 – Delbegetey massif; in the Zharma-Saur zone: 7 – Arkat massif, 8 – Karakoltas Massif, 9 – Kandygatai massif, 10 – Biesimas massif, 11 – Korgantas massif (off–scale), 12 – Keregetas Massif (off-scale), 13 - Upper Espe Massif (off-scale). The numbers in the rectangles are the age values of the leukogranites, determined by U–Pb dating using zircons. The inset shows the position of the structural and formation zones of the Ob-Zaisan folded system.
