Abstract

The Montalto Formation consists of a succession of slate, greywacke, quartzites, and polygenic conglomerates cropping out in the Dúrico-Beirã area of northern Portugal. The formation is of interest because it contains mixed volcaniclastic sequences that record changes in marginal-marine depositional environments and because it is associated with regional tectonic and magmatic processes. The Montalto Formation can be divided into three lithological associations that record a shallowing-upward sequence.
