Cinemática, dinámica y modelo deformacional de la falla Gramalote en el sector vereda Jacome, en el municipio de Gramalote, Norte de Santander.

Abstract

In the sector of the Jacome trail in the municipality of Gramalote, sedimentary rocks of Cretaceous age of the Tibú-Mercedes, Aguardiente, Cogollo, La Luna and Colón-Mito Juan Formation outcrop. The study area has an area of 7 km2 where a geological cartography was developed at a scale of 1:10,000, where 173 stratification planes were recorded. The structural control was carried out along 71 outcrop stations which resulted in 706 measured diaclase planes. With this information, 4 tectonic blocks are established whose data were analyzed and processed by means of the Wintensor 5.9.2 program, these indicate three main directions of the maximum horizontal stress, which allow identifying the temporality of the deformation events, the first with an old E-W vector that has evolved with a clockwise rotation of the stress field, from NE-SW to NW-SE, the latter more associated to the current transpressional regimes of the Bucaramanga faults.
