Institut für Geowissenschaften Mathematisch-Naturwissenschaftliche Fakultät Universität Potsdam MAFIC MAGMATISM IN THE EASTERN CORDILLERA AND PUTUMAYO BASIN, COLOMBIA: CAUSES AND CONSEQUENCES Dissertation zur Erlangung des akademischen Grades Doktor der Naturwissenschaften “doctor rerum naturalium” eingereicht an der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Potsdam von Dipl.-Geol. Mónica Fernanda Vásquez Parra Geb. 25.03.1977 in Bogota, D.C, Kolumbien Potsdam, im Januar 2007 “El Señor te cuidará en el hogar y en el camino, desde ahora y para siempre” Salmo 121:8 ABSTRACT The Eastern Cordillera of Colombia is mainly composed of sedimentary rocks deposited since early Mesozoic times. Magmatic rocks are scarce. They are represented only by a few locally restricted occurrences of dykes and sills of mafic composition presumably emplaced in the Cretaceous and of volcanic rocks of Neogene age. This work is focused on the study of the Cretaceous magmatism with the intention to understand the processes causing the genesis of these rocks and their significance in the regional tectonic setting of the Northern Andes. The magmatic rocks cut the Cretaceous sedimentary succession of black shales and marlstones that crop out in both flanks of the Eastern Cordillera.
