Resumen:
|
The neogene infill in the Campo de Calatrava basins (Central Spain), is dominated by lacustrine and fluvial continental deposits in isolated conditions what complicate the correlations. In this paper is introduced the rock magnetism to stratigrafic correlation and geochronolgic calibration of rocks secuences of the continental neogene infill. A total of twelves partial magnetoestratigraphic sections have been constructed which represents the upper neogene o f four diferents basins. The cross-correlations have been made with the Geomagnetic Polarity Time Scale (GPTS), by the existence o f two well-defined paleontological sites (Las Higueruelas and Valverde II), and six radiometric date in volcanic sites. The main contribution of this paper is to place this infill between Lower Pliocene (C3n.3n) and the late Pliocene (C2r). Others conclusions have been found such as: the sedimentation rate which finished this infill was of 35 m/Ma, as well it has been locate a sedimentary break in the upper zone of the Gilbert chron (2Ar).
