... into three age groups: Late Paleoproterozoic (e.g., Chiney complex, Malozadoisky massif), Late Mesoproterozoic (e.g., Srednecheremshansky massif), and Neoproterozoic (e.g., Kingash complex, Yoko-Dovyren massif, and massifs in the center of the East Sayan Mts.). In most massifs but Chiney the initial magmas...

...Fig. 1. ( a ) Schematic geological map (after Tarasov and Shvedov, 2010 ) and the location ( b ) of the Kingash complex, Eastern Sayans, Krasnoyarskiy kray, Russia. The presently reported occurrences of melonite are shown by the red symbol. ...

...Fig. 1. Schematic occurrence of ore-bearing complexes in the East Siberian metallogenic province. 1 , continents and microcontinents; 2 , exposures of the Precambrian basement of the Siberian craton; 3 – 7 , folded areas: 3 , Riphean; 4 , Riphean–Vendian; 5 , Early Caledonian; 6 , Late...

...; 11 , Early Proterozoic Tuksha migmatite–plagiogranite complex; 12 , Late Archean (probably Early and even Late Proterozoic) Kingash dunite–wehrlite–picrite complex of small layered differentiated massifs; 13 , Late Archean–Early Proterozoic(?) Idar dunite–harzburgite complex (stocks, dikes, lenses...

...G. I. Shvedov; N. D. Tolstykh; V. V. Nekos; L. N. Pospelova We studied PGE minerals in the Kingash Massif made up of basic and ultrabasic rocks. They are represented by sobolevskite, kotulskite, michenerite, froodite, paolovite, sperrylite, and irarsite, which are quantitavely dominated by Pd...

... and right banks of the Kingash River contain horizons of calcite marbles and calciphyres and alternates with thin (1–5 m) layers of high-Mg schists similar in composition to talc-clinopyroxene-amphibolites and talc-serpentine-amphibolites. They occur as a tectonic plate on the complex of migmatized gneisses...

... and Yenisei Ridge; 4 – 6 — metamorphic complexes of Kan Block; 4 — Proterozoic, 5 — Middle Riphean, 6 — Late Riphean; 7 — Riphean structures of Derbin anticlinorium. Areas of Cu-Ni ore occurrences and deposits: I — Kan: 1 — Kingash, 2 — Kungus; II — Biryusa: 3 — Barbitai and others.; III...

... is difficult for the lack of felsic metavolcanics and granitoids except for tonalite and trondhjemite veins. The Sm-Nd whole-rock and mineral isochron ages for the cumulate ultramafics and gabbro of the Kingash complex in the Idar terrane are ~1400 and ~870 Ma, respectively ( Gertner et al., 2005...

... formations. Circum-cratonic zoning marked by Riphean, Paleozoic, and Mesozoic black-shale complexes has been recognized in distribution of Pt-bearing structure-formational complexes. This zoning reflects the geochemical evolution of the Earth’s crust and mantle. The deposits which are the most promising...

... to a suite of dunite–peridotite–pyroxenite complexes, namely Shumikha, Kingash, Golumbei, Tartai, Ognit, Zhelos, Tokty-Oi and Malyi Zadoi, associated with the Yoko–Dovyren complex in the Baikal–Patom zone. These complexes formed in a continental margin setting in the East Siberian metallogenic province (e.g...

... with ultramafic–mafic magmatism. The Chinei deposit (1880 Ma) is related to the Superior LIP (Canada). The Yoko-Dovyren intrusion and Kingash Cu–Ni–PGE deposit are assigned to the Franklin LIP ( Ernst and Jowitt, 2013 ; Polyakov et al., 2013 ). The unique Cu–Ni–PGE deposits of the Norilsk district are confined...

... recoupé par des intercalations et des injections de pyroxénite et de péridotite à plagioclase, qui font preuve de différences en teneurs de la fraction sulfurée. Vers le haut du complexe, on trouve surtout des gabbronorites avec interdigitations de venues de pyroxénite et de gabbro porteurs de...
