Reference information

Comments Associated with High-K calc-alkaline and shoshonitic rocks of Shakhtama pluton. Potassic and argillic alteration. A rich part of the deposit was mined out underground (37 Mt at 0.1-0.5% Mo and 0.1 to 0.2% Cu). Pb-isotopes suggest important crustal component in magmatic source. Mongol-Okhotsk Fold Belt. Mining, underground.
