Las Karmidas Cave (Puebla State, Mexico) is an unusual type of pseudokarstic cavity generated by piping and erosive processes within the contact of a diamicton and an overlying Quaternary ignimbrite. Morphological evidence suggests that the cave was

The Tierra Blanca Joven (TBJ) eruption from Ilopango volcano deposited thick ash over much of El Salvador when it was inhabited by the Maya, and rendered all areas within at least 80 km of the volcano uninhabitable for years to decades after the erup

Garnet-bearing rhyolitic flows and ignimbrites occur together with an andesitic lava flow in the central part of the Mesa Central in the western part of the Mexican state of San Luis Potosi, forming a typical K-rich sub-alkaline intra-plate tectonic

The Ilopango caldera is located in the central part of El Salvador, within the right-lateral El Salvador Fault System (ESFZ) and adjacent to the capital city of San Salvador. The caldera has a polygonal shape of 17 × 13 km and hosts an intra-caldera

Boiling-over dense pyroclastic density currents during the formation of the ~ 100 km3 Huichapan ignimbrite in Central Mexico: Stratigraphic and lithofacies analysis

A lithofacies analysis of the Huichapan ignimbrite has been undertaken to evaluate its depositional history from large pyroclastic density currents. The Huichapan ignimbrite is a massive ignimbrite sheet with a maximum runout of at least 55 km and th
