Using high-resolution ammonite biochronostratigraphy to date volcanogenic deposits preserved in middle Jurassic carbonate platforms successions of the westernmost tethys (southeastern iberian range, spain)

The Middle Jurassic successions that are currently exposed in eastern Spain (southeastern Iberian Range) were deposited in a system of shallow carbonate platforms, constituting the western margin of the Alpine Ocean, and display a series of successively interbedded volcaniclastic rocks and minor lav...
