Platinum Potential of the Stanovaya Metallogenic Zone (Far East, Russia)

摘要

The Stanovaya metallogenic zone occurs along the southeastern margin of the Northern Asian Craton with a length of 1300 km and a width of -250-300 km. The metallogenic zone is located in the eastern part of the Stanovoi megablock limited by the Stanovoi deep fault from the north and by the Mongol-Okhotsk deep fault from the south. A megablock surrounds the Aldan protomassif, represented by a folded-block or granite-greenstone area that underwent Mesozoic tectonomagmatic activization. The structure of the territory includes a number of blocks composed of Early Archean (Zverevsko-Chogarskii and Zeiskii Complexes) and Late Archean (Stanovoi and Gily-uiskii Complexes) metamorphic rocks. Intercratonic troughs are filled by formations of the Early Protero-zoic Dzheltulakskii Complex represented by phyllite-like, biotite, and two-mica schists, quartzites, meta-conglomerates, and metaeffusive rocks [1].
