Abstract

Three new drillings, deeping from 180 to 260 m, were holed in the urban area of Madrid during 1983. The drillings aimed to test the lithostratigraphic relationships within Miocene deposits that form the subsurface of this city. D.rilling SGOP-l was placed in Av. Portugal and it dept until 256 m. The stratigraphic sequences is made up mainly by arkosic sands and sandy-clayey deposits, throughing down greenish lutites and a few gypsum beds. Drilling SGOP-2 was placed in San Blas. It dept until 203 m and it cutted three main lithostratigraphic units that might be correlated with nearby autcropping miocene deposits in eastern Madrid. At the same, dril1ing SGOP-3 cross over those units in Vallecas, southern Madrid. Herein, drilling stopped at 180 m. A correlation network may be stablished from these new data when they are compared with previous subsurface information of Madrid.
