Gold is associated with arsenopyrite–pyrite–quartz–siderite mineralisation in a peralkaline granite porphyry dyke which intrudes Lower Palaeozoic metasedimentary rocks. The granite dyke has a thickness of 30 to 60 m, and extends discontinuously for 7 km (Fig. 2 ).

 · It is composed of a peralkaline, cryolite-bearing core facies and a peraluminous to metaluminous, oxidized, fluorite-bearing border facies, generated by autometasomatic processes after the crystallization of the core facies. A metaluminous to peralkaline hypersolvus granite is comagmatic with the albite-rich granite.

 · The Keivy peralkaline granite complex consists of 2650-2660 Ma peralkaline granites, 2670 Ma syenogranites, and 2680 Ma alkaline syenites. The granites form sheet-like bodies with thicknesses of a few …

 · The rare metal peralkaline granites consist of K-Na feldspar, quartz, albite, arfvedsonite, aegirine, fluorite, and diverse rare metal minerals ranging up to 25 vol percent. Ore minerals are represented by elpidite, gittinsite, and zircon; pyrochlore (Nb); rare metal flurocarbonate and monazite (REE); and polylithionite (Li).

 · The deposit, which was discovered by the authors, is composed of dome-shaped stocks of rare metal peralkaline granite covering 0.85 km and represents the late plutonic phases of the Devonian (380-390 Ma) multiphase Khaldzan-Buregtey peralkaline granite massif. The formation of the massif took place during tectonic extension, as shown by the ...
