Identificación y caracterización de las unidades litosísmicas cenozoicas en el área de Santiuste de San Juan Bautista (Segovia), sur de la cuenca del Duero (España)

Abstract

The analysis of natural gamma, spontaneous potential and resistivity survey well logs from the borehole of Santiuste de San Juan Bautista (Segovia), has identified several lithosismic units in the subsurface of this region to be able to differentiate lithology and a set of electrofacies. The correlation of discrete units in the survey using geophysical criteria lithostratigraphic units defined in surface based on lithological criteria, has helped define the geophysical parameters characterizing surface lithostratigraphic underground and the ability to identify the Cenozoic units in the subsurface while one of the conditions required by the International Stratigraphic Guide so that they can be considered as units with formal status is met.
Your sedimentological interpretation defines that formed by a set of progradating to be seen in the well log superimposing different litosismic units with a sequential architecture marked coarsening upward and partners, possibly a front saw rising continuously during the Cenozoic fans.
