Materials for understanding the genesis of the Monetnaya Dacha emerald deposit in the Urals

Emerald mines are located on the eastern slope of the Urals among a swampy forest area 70 km northeast of Sverdlovsk, in the former Monetnaya forest dacha. The formation of the Emerald Mines region involves metamorphic and igneous rocks with abundant and varied vein derivatives. Sedimentary rocks have not been identified, except for modern sandy-clayey deposits. The rocks composing the region can be divided into the following groups: northeastern porphyritic granite, western granite, eastern intrusion, including southeastern gabbro, a band of amphibolites and a northeastern complex of metamorphic rocks.
