...V.I. Krupchatnikov; V.V. Vrublevskii; N.N. Kruk Abstract Geological, geochemical, and isotope (Sr, Nd, and O) parameters of Early Devonian (405 Ma) volcanics of southeastern Gorny Altai (Aksai and Kalguty volcanotectonic structures) are discussed. The studied igneous rock association comprises...

... granites of the Dzhulalyu Massif and veined elvanites of the Kalguty Massif. The Dzhulalyu Massif is located in southeastern Altai [ 9 ] and is less than 1 km 2 in area. It makes up a large protrusion of bedrocks among glacial deposits. The massif is composed of tourmaline-muscovite (with Li-bearing...

.... The anomalies may have a deep source only at the Aryskan site in the East Sayan ( q = 77 mW/m 2 ) while high heat flows of 75–90 mW/m 2 obtained for the Mesozoic Belokurikha and Kalguty plutons appear rather to result from high radiogenic heat production in granite, which adds a 25–30 W/m 2 radiogenic component...

The largest mineral deposits are Kholzun (Fe, P 2 O 5 ), Karakul (Co, Bi), Sinyukha (Au), Aktash and Chagan-Uzun (Hg), Ozernoe and Pogranichnoe (Ag), Kalguty (Mo, W), Alakha (Li, Ta), Rudnyi Log (Y,Fe-specularite...

...-lepidolite granites [ 2 ]. These granitoids occur in the Irtysh compression zone within the band of development of the Kalba complex massifs but among the host rocks. The dikes are oriented across the strike of the band, which indicates their specific independence, at least, in respect of the structural...

..., the largest commercial deposits are confined to rift structures or deep-fault zones. Formation of large ore deposits was determined by the spatial co-occurrence of plume magmatism and within-plate rifting and the active mantle–crust interaction. 06 07 2005 © 2006 UIGGM, SIBERIAN BRANCH OF THE RAS...

... Jurassic for the late rare-metal-granite one. New U-Pb and Rb-Sr isotope dates generally confirmed and refined the above-presented ages ( Table 1 ). Note that the Early Jurassic age (196–182 Ma) of the rare-metal-granite association (Chindagatui-Kalguty complex) was confirmed by the Rb-Sr isochron method...
