“…Specified were the regularities of formation and criteria of predicting of gold-ore sites of unconventional gold-sulphide vein-embedded type, represented by the industrial Suzdal deposit and promising small deposits and ore occurrences (Zhaima, Mirazh, Baibura and others) [16][17][18][19][20]. According to their genesis, these deposits are referred to the hydrothermalmetasomatic type, formed in the Hercynian cycle under collisional geodynamic environment (С2-3-С3), localized in the Zaisan sutural zone and of a significant material value [4,8]. The deposits are characterized by spatial selective confinement to the island-arc volcanic-carbonate-terrigenous formation of inter-arc deflections (the Arkalyk suite С1V2-3), considered as a favourable ore-hosting medium (increased carbon and carbonic content) for the deposition and concentration of gold.…”

“…The most productive system for gold-sulphide mineralization is the collision ore-magmatic system, which reflects the leading ore-control role of the deep fracture system, which caused the rhythmic-tectonic pulsating inflow of ore-bearing fluids (under conditions of rhythmic tectonic compression-stretching motions) and the introduction of synchronous with them gipabissal small intrusions and dikes of gabbro-dioritegranodiorite-plagiogranite series (С2-3-С3) connected with deep magmatic sources of mantle-crust origin. Of special importance is the magmatic control of mineralization, determining the attribution of widely developed in ore fields plagiogranites and dykes of the Kunush complex (sodium alkalinity and high Sr-content) to adacite granitoids, the metabasite derivatives [8,15].…”

“…There are over 450 deposits and ore manifestations of gold in the Zaisan suture, including the unique deposit of Bakyrchik, the large Suzdal deposit, and gold-ore sites of DolonoSai, SaryBulak in the adjacent Chinese area. According to the set of geological-geophysical data concerning the deep structure, the Zaisan suture is fixed by an elevated asthenospheric layer, oriented along the line "the Semipalatinsk city -the Zaisan lake" and the meta-basalt surface [1,8]. Geophysical methods (gravimetric, magneto-exploration, IP, etc) are also effectively used to identify and trace hidden gold-bearing structures.…”

“…An example is the Kyzylov latitudinal deep fault, confining large gold deposits (Bakyrchik, Bolshevik, Deep Log, etc.) (Figure 1) [2,8]. The ore-controlling role of latitudinal faults is accurately manifested in rare-metal sites of the Kalba-Narym zone (the Asubulak ore field, others), and it also was noticed on the Smirnov gold-silver deposit in the South Ural Mountains [9].…”

The region under consideration is part of the Central Asian mobile belt system, organized by a large geo structure of the Greater Altai (GA), which integrates geological structures of the Rudny Altai, Kalba, Zharma-Saur and adjacent districts of Russia and China. The regional goldore sites vary by ore formation types, age, geological formation conditions and mineralization scale. The largest among them are the Ridder-Sokolny gold-polymetallic deposit in the Rudny Altai and the Bakyrchik deposit of the gold-sulphide-carbonaceous type in West Kalba, comparable in many ways with the world sites of Sukhoi Log and MurynTau in the black shale strata. In recent years, much attention was paid to prediction and assessment of the unconventional (apocarbonate) goldsulphide type of mineralization, associated with the island volcanic-carbonate-terrigenous formation С1v2-3 (the Suzdal deposit and others). The present paper considers new results acquired from the studies of the gold-ore sites of the Suzdal type.

“…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].…”

Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining and metallurgical industry of Eastern Kazakhstan. To substantiate the scientific background for mineral exploration, we study microinclusions in minerals from gold and rare-metal fields, as well as trace-element patterns in ores and their hosts that may mark gold and rare-metal mineralization. The revealed compositions of gold-bearing sulfide ores and a number of typical minerals (magnetite, goethite, arsenopyrite, antimonite, gold and silver) and elements (Fe, Mn, Cu, Pb, Zn, As, and Sb) can serve as exploration guides. The analyzed samples contain rare micrometer lead (alamosite, kentrolite, melanotekite, cotunnite) and nickel (bunsenite, trevorite, gersdorffite) phases and accessory cassiterite, wolframite, scheelite, and microlite. The ores bear native gold (with Ag and Pt impurities) amenable to concentration by gravity and flotation methods. Multistage rare-metal pegmatite mineralization can be predicted from the presence of mineral assemblages including cleavelandite, muscovite, lepidolite, spodumene, pollucite, tantalite, microlite, etc. and such elements as Ta, Nb, Be, Li, Cs, and Sn. Pegmatite veins bear diverse Ta minerals (columbite, tantalite-columbite, manganotantalite, ixiolite, and microlite) that accumulated rare metals late during the evolution of the pegmatite magmatic system. The discovered mineralogical and geochemical criteria are useful for exploration purposes.

Purpose. Identification of geophysical criteria to determine ore content indicators within the territory relying upon systematization of both geological and geophysical materials. Methodology. The research involved innovative techniques used in the field of geology, i.e. GIS technology, and such theoretical scientific approaches as analysis and synthesis of petrophysical data, and data of geophysical anomalies in the context of the analyzed ore zone. Findings. Petrophysical characteristics of Akmai-Katpar ore zone rocks have been generalized and systematized. Petrophysical model of the ore zone has been developed; changes in petrophysical rock characteristics have been defined in terms of Silurian, Devonian, Carboniferous, and Permian systems. The obtained parameters of the petrophysical model are integrated with the identified geophysical anomalies. Geophysical indicators of ore content of the rare-metal ore zone have been determined. Cartographic documents have been specified which made it possible to perform layer-by-layer mapping of Akmai-Katpar ore zone. Originality. For the first time, the systematized geological and petrophysical materials have been applied to build the petrophysical model of Akmai-Katpar ore zone and improve geophysical forecasting criteria. Practical value. It consists in the use of geophysical forecasting criteria while identifying prospective areas where rare metals occur.
