Evidence for rapid epithermal mineralization and coeval bimodal volcanism, Bruner Au-Ag property, NV USA
… <16.34 Ma, post-mineral rhyolitic volcanism and normal faulting; and <16 Ma to present, continued faulting and dismemberment of the mineral system.The close spatial and temporal association of veining with coeval volcanic units suggests that Au-Ag-S traveled along similar structure …

Significance of magma mingling and mixing during the formation of the host-rock successions of Archean massive sulfide deposits in the Noranda camp, Abitibi subprovince, Quebec, The
… setting. As magma mingling and mixing indicate bimodal volcanism, a hallmark of crustal extension, it is proposed here that volcanic textures produced by these processes can be used to identify areas in volcanic belts that are favorable for volcanic-hosted massive sulfides.

Engineering geological characterization of volcanic rocks of ethiopian and sardinian highlands to be used as construction materials
… formation represents alkaline-subalkaline bimodal mafic-felsic volcanic series. The mafic volcanic suite is more abundant and characterized by alkaline basalts and minor silica undersaturated rocks (basanites) and the felsic suite is relatively less abundant and represented by strongly …
