Three distinctive igneous suites crop out in the El Fuerte block, northwestern Mexico. The oldest of these suites is the Realito Gabbro, which intrudes the Middle-Upper Ordovician Río Fuerte Formation. This gabbro yielded an Early Silurian U-Pb zircon age of ca. 430 ± 15 Ma. The Topaco Formation is a greenschist facies metamorphosed volcanosedimentary sequence. Basaltic rocks of this unit yielded a Late Jurassic U-Pb zircon age of 155 ± 3.5 Ma (Kimmeridgian). The Guamuchil Formation mainly consists of basaltic flows overprinted by greenschist facies contact metamorphism. A sample of this unit yielded a Late Cretaceous U-Pb zircon age of 73 ± 1.5 Ma (Campanian). Geochemical signatures of the three suites suggest an island arc tholeiitic envi...
