Cuencas de traccion sinistrales en la falla de minas del Sistema Cauca-Romeral, en las cercanias de Medellin, Colombia
Jorge Julian Restrepo, Jean Francois Toussaint
Abstract
Resumen. La falla de Minas, uno de los ramales mas orientales del Sistema Cauca-Romeral, localizado entre las cordilleras Central y Occidental de Colombia, muestra evidencias de movimientos sinistrales recientes. En efecto, en zonas cercanas a Medellin, la traza de la falla presenta escalonamientos que han producido dos cuencas de traccion ("pullapart basins"), de hasta 1 km de largo y 0,15 km de ancho. El analisis geometrico de las depresiones indica que corresponden a cuencas de traccion generadas por un movimiento sinistral. Abstract. The Minas fault, one of the easternmost branches of the Cauca-Romeral Fault System, located between the Central and Western Cordilleras of Colombia, shows characteristics of recent sinistral movements. In a zone in the vicinity of Medellin, the fault presents steppings which have produced two pull-apart basins about 1 km long and 0.15 km wide. The geometrical analysis of the basins in relation to the steppings indicates that they were produced by sinistral movements on a wrench fault.
