Petrographic and geochemical characteristics of upper Aptian calc-alkaline volcanism in San Miguel de Allende, Guanajuato state, Mexico
A volcanic sequence formed by calc-alkaline basalts and basaltic andesites interbedded with pelagic limestones, black shales, radiolarites, and epiclastic rocks that are in tectonic contact with flysch-like strata, is reported in the vicinity of San Miguel de Allende, in Guanajuato state. An upper...

| description |
A volcanic sequence formed by calc-alkaline basalts and basaltic andesites interbedded with pelagic limestones, black shales, radiolarites, and epiclastic rocks that are in tectonic contact with flysch-like strata, is reported in the vicinity of San Miguel de Allende, in Guanajuato state. An upper Aptian age is suggested by paleontological evidence. The sequence is interpreted as the eastern remnant of an allochthonous, lower Cretaceous volcanic stage in central Mexico.
