Magmatic source, petrogenesis, and tectonic setting of the Concepción del Oro Igneous Complex: a geochemical and isotopic (Rb–Sr and Sm–Nd) study of a late complex of the Cretaceous–Eocene Mexican Magmatic Arc
During the Mexican fold-and-thrust belt tectonics, the inboard migration of long-term cordilleran magmatism typifies the geological setting during...

Tectono-magmatic domes: the stationary plate equivalent of a linear volcanic chain
Tectono-magmatic domes are large topographic, structural and volcanic features produced by mantle plume activity in a stationary plate environment....

Petrologically controlled oxygen isotopic classification of cogenetic magmatic and metamorphic sapphire from Quaternary volcanic fields in the Eifel, Germany
Gem sapphire is commonly retrieved from primary and secondary deposits associated with alkali basaltic fields, but its source rocks are rarely...

Magmatic origin for the massive sulfide ores in the sedimentary country rocks of mafic–ultramafic intrusions in the Midcontinent Rift System
Some mafic–ultramafic intrusions in the North American Midcontinent Rift System host disseminated to massive sulfides of magmatic origin. Massive...
