Information about the mineral resources plot
The subsoil site "Tulekit" is located on the left bank of the Tsipa River in its middle course, 114 km north-east of the regional center with Bagdarin.
The main orographic units of the region are the Babanty Mountains, the Olingda Depression, and the eastern part of the Tsipa Depression. Three types of relief are distinguished within the area:
- Alpine steep-slope sharply dissected relief with a predominance of factors of erosion, glacial gouging, frost weathering (absolute marks - 1600-2100 m);
- mid-mountain, often flat-topped dissected relief with flattened slopes, the predominant factors are erosion, denudation, frost weathering, solifluction (absolute marks - 1200-1600 m);
- low-mountain, ridge-hilly relief of intermontane depressions with a predominance of factors of the river, lake-river, glacial accumulation, erosion (absolute marks are less than 1200 m).
The mid-mountainous relief occupies the main part of the area. The slopes are gentle (20-25 °). This type of relief has features of both high and low mountainous.
The main water artery is r. Tsipa (Vitim tributary) is suitable for the movement of light boats from the Uyu meteorological station to the Bount settlement. The rest of the streams are typically mountainous, with Y-shaped valleys in the upper reaches and trough-shaped ones in the lower reaches. In winter they freeze to the bottom. In the valleys of the Talikit and Amnunna Tsipinskaya rivers, ice up to three meters thick is formed in winter, which finally melts in early July.
The climate of the region is sharply continental. Winter is long and usually with little snow. Summer is short and hot. The minimum temperatures in January are up to -40 ° - 50 °, the maximum in July is up to + 30 °. Annual precipitation is 400-430 mm, maximum rainfall occurs in July-August. The snow cover melts in mid to late June and appears in August and early September. Permafrost is widely developed. The active layer is 1-1.5 m. Freeze-up on rivers and lakes begins at the end of September-first half of October, ice drift - in May-June.
Geological characteristics of the subsoil area, indicating the presence of deposits (deposits) of minerals and reserves (resources) for them:
The licensed area is located within a large ore-controlling structure identified by airborne geophysical work (Shpilkov, 1972) called the Kudur-Talikit ore zone (KTRZ).
The geological structure of the zone is rather complex. Its main part is represented by intensely metamorphosed terrigenous rocks of the Amatkan Formation of the Vendian, which breaks through with granites of the Vitimkan intrusive complex and subvolcanics of the Kudur complex and is overlain by volcanics of predominantly felsic composition.
Vendian formations are represented by various schists (sericite-feldspar-quartz, biotite-quartz-feldspar, biotite-cortical dierite), secondary micaceous quartzites, quartz-feldspar-sericite meta-rocks of metasomatic genesis, marbled limestones with carbonate-interbedded, metagravelites and metaconglomerates, hornfelsed massive or layered.
Subvolcanic formations of the Kudur complex are represented by quartz porphyries, light gray, massive, or shale, in places K-feldspar.
Intrusive rocks of the Vitimkan complex, widely developed outside the zone, are represented here by small bodies of granitoid, aplites, and pegmatites. The lenticular bodies of gabbro-diorites of the Biram'ya complex, as well as dikes of diabase porphyrites and microdiorites of conventionally Mesozoic age, are not widespread.
