Molybdenite is the only common concentrator and economic source of Re. This is because MoS2-ReS2 effectively comprises a solid solution. The association of Re with Mo in this manner suggests that Mo and Re may also behave similarly during magmatic processes. 

Rhenium contents of molybdenties have been derived from two sources the 

Rhenium contents are low in molybdenites associated with reduced Sn-mineralized granites, and in molybdenites associated with the ilmenite-series granites of Japan. Ilmenite-series granites obtained their 

Behaviour of other elements in molybdenite are highly consistent with ore element ratios in associated mineral deposits and strongly suggest that their control is dominantly that of their availability in the associated magmas at the time of hydrothermal fluid exsolution and transport.
