Duque-Trujillo, Jose; Pardo, Natalia; Lucchi, Federico; Arias, Manuel; Valencia, Luis G; Bustos, Emilce; Arnosio, Marcelo; Pulgarin, Bernardo: Fault planes and striation data collected by compass from the Doña Juana Volcano, Colombia [dataset]. PANGAEA, https://doi.pangaea.de/10.1594/PANGAEA.923685 (dataset in review)
Abstract:
The data here contained include strike and dip of the measured fault-planes, and trend and plunge of the linear kinematic indicators (i.e., fault striae, mineral fibers, steps, pluck marks, and tool marks) recognized on each fault plane and measured at outcrop scale using a Brunton Geo pocket transit. The collected data was mainly collected on rocks that constitute the Doña Juana Volcano basement, the Jurassic micaceous schists from the Cajamarca Complex (Blanco-Quintero et al., 2014; García et al., 2017), and Cretaceous metavolcanic rocks of the Quebradagrande Complex (Nivia et al., 2006). However, some fault planes were found cutting recent volcanic deposits from the Doña Juana Volcano. Fault and slickenline data were used to develop a fault kinematic analysis by applying the straight dihedral method for slickenline inversion (Angelier, 1979, 1984) to obtain the paleostress field during the Pleistocene-Holocene evolution of the Doña Juana Volcano. The results suggest an active oblique (right-lateral strike-slip and dip-slip normal displacement) tectonic activity with the main stress tensor oriented E-W. The resulting basement-complex faulting strongly controls the development of diverse volcano-tectonic summit depressions linked to destructive stages of overlapping volcanic edifices and defining major volcano-stratigraphic unconformities.
