New data on geology and geochemistry of the Talovskii gabbro-ultrabasic massif (southern Urals)

The interior structure and geochemistry of ultrabasic rocks and gabbroids of the Talovskii massif have been considered. Types of gabbroids that are impoverished and enriched in light REE are recognized. Accessory chrome-spinelides of ultrabasic rocks are enriched in trivalent iron and impoverished in aluminum, making this complex more similar to platinum-bearing massifs. The occurrence of a unite-harzburgite association and numerous injections of wehrlite-clinopyroxenite-gabbro in a single section of restites are due to their formation above a subduction zone.
