• Resumen

  • Geophysical and geomorphological techniques, were combined with field investigations and facies analysis in order to locate and accurately characterize maar volcanic structures of Campo de Calatrava Volcanic Field. Two kind of maar morphologies can be identified: (i) “Sierra Type maar” if the explosive volcanic processes affected the lower Ordovician slates and quartzites. (ii) “Llanura Type maar” if the explosive volcanic processes affected the Pliocene arcosic sandstones. These features favour a higher preservation of “Sierra type” than “Llanura Type” because the Pliocene sandstones are more susceptible to be eroded. In this second case, maars ussually do not preserve the pyroclastic rim and only can be identified by their lacustrine deposits. Carbonatic fine-grained outcrops clearly reveal the bowl-like structure of this second type of maar lakes
