Abstract

This project was based on the construction of a radiometric database of the Coast and Western Cordillera of Ecuador, to understand the geodynamic evolution of the area based on statistical analysis and KDE (Kernel Density Estimate) diagrams. A total of 4850 individual data were collected, of which 3870 belong to the Coast and Western Cordillera and represent the radiometric dating of 283 samples. The statistical analysis indicated that there are no radiometric dates in the NW zone of the coastal region and that the most used method is the K-Ar method. The 4850 individual data were represented in KDE graphs and classified into four groups: Coast, Western Cordillera, “Miocene River Sand Samples”, and “Miocene Offshore SW Ecuador”, in which there are ages from the Precambrian. These ages are legacy peaks with a probable source from the Cordillera Real. The 3870 individual data points were equally represented on KDE plots and classified according to isotopic system. The KDE of magmatic U-Pb reports crystallization ages for the Pujilí (90.8 Ma) and San Juan (86.4 Ma) Formations, intrusive in the Silante Formation (10.3 Ma), and for the Macuchi Unit (42.1 Ma) in the Cordillera Western. On the Coast, reported ages for the Redondo, Pascuales and Dique Chivería intrusives with 98.4, 95.9 and 86.6 Ma respectively. The KDE of detrital U-Pb indicates MDA (Maximum Deposition Age) ages of 56, 40.2, 16.6 and 10.2 Ma for the Saquisilí Unit, Apagua Formation, Silante Formation and for the Saraguro Group respectively for the Western Cordillera. On the Coast, it shows MDA ages of 60.2, 43.3, 31.3, 20.6, 14.2, and 10 Ma that correspond to the Azúcar Formation, Ancón Group, Zapotal Formation, Progreso Formation, Sube y Baja Formation, and Angostura Formation respectively. The thermochronology KDE represents the ages obtained by K-Ar, Ar-Ar, U-Th, U-Th/He, and Re-Os. In the KDE thermochronology of the Coast, a K-Ar age peak of 73 Ma was obtained for the Piñon Formation, which could indicate a reset due to tectonic activity associated with an accretion event that formed the basement of the Coast and Western Cordillera at the end of the Late Cretaceous.
