AbstractA new continuous section with Aeronian to lower Telychian graptolites is described near Corral de Calatrava (province of Ciudad Real). The transition between the "Criadero Quartzites" and the overlying black shales is detailed. The section is correlated with another similar sucessions around the Ordovician/Silurian boundary in the southern part of the Central lberian Zone, and chronostratigraphic aspects are briefly analyzed and discussed. The sedimentation of the "Criadero Quartzite" took place during Rhuddanian to late Aeronian times; a minor hiatus was developed at the upper limit with the graptolitic black shales. The base of the latter is not older than the palmeus sub-biozone of the early Telychian.
