Tectonics and Metallogeny of East Kazakhstan

Abstract

General regularities in the formation of tectonic and metallogenic structures are considered as a scientific basis for forecasting new deposits of nonferrous, precious and rare metals in the territory of East Kazakhstan and are considered on the basis of modern geotectonic concepts of the Earth self-development. Regular connections between the main ore-bearing structures and the leading geological-industrial types of deposits are determined with features of the deep crustal structure and certain geodynamic settings of various geotectonic cycles and eras (from the Precambrian to the Quaternary). The belt placement of ore deposits is emphasized with the identification of four ore belts: Rudny Altai (Cu, Pb, Zn, Au), West Kalba (Au, Ag), Kalba-Narym (Ta, Nb, Be, Li, Sn, W) and Zharma-Saurs (Cr, Ni, Co, Au, TR). In the location of gold ore deposits, the Zaisan suture zone, formed in the collision zone of the Kazakhstan and Siberian lithospheric plates, is the ore-controlling value. Spatial-genetic connections of rare metal and rare-earth deposits with granitoid belts formed in post-collision (orogenic) geodynamic conditions of Permian time are determined. The research is aimed at strengthening the mineral and raw material base for the operating enterprises of the East Kazakhstan region.

Mineralogical Tracers of Gold and Rare-Metal Mineralization in Eastern Kazakhstan

“…Roman numerals in circles stand for names of shear zones: I = Irtysh, II = Kalba-Narym, III = West Kalba, IV = Char. Numbers 1 to 11 are gold (1)(2)(3)(4)(5)(6)(7)(8)(9) and pegmatite (10,11) deposits and occurrences (see legend).…”

“…The gold-bearing Fe, Mn, Cu, Zn, Pb, Au, Ag, etc. ores in the latter are associated with Devonian basalt-andesite-rhyolite volcanism (D 1-3 ) and controlled by large faults [2,3]. Many large and giant Cu, Pb, and Zn deposits of Rudny Altai (Orlovka, Artemiev, Ridder-Sokolny, Maleevsk, etc.)…”

“…The detection of hidden, buried, and unconventional resources requires new prospecting and exploration technologies based on comprehensive knowledge of geology and metallogeny. We have studied gold and rare metal mineralization in Eastern Kazakhstan for years while working for production enterprises [2][3][4][5][6][7][8][9][10]. Our results provided updates to the regional and local mineralization patterns, geologicalgenetic models, and exploration criteria for classification and appraisal of mineral resources [3].…”
