A Unique Find of Rhenium-bearing Wolframite in Ongonites of the Russian Far East

Resumo

Accessory wolframite with an extraordinarily high rhenium content (2.93–3.52%) in ongonite from the Badzhal area in the Far East is described. The capacity of tungsten isomorphic substitution with rhenium in wolframite is studied. The appearance of rhenium-bearing wolframite is caused by specific conditions of the crystallization of rare-metal granite magmas.
