Attribute-based processing of lineament data: An example from Cesar-Rancheria and neighbour provinces in Colombia

Abstract:

The northern part of Colombia provides an opportunity for lineament collection over all types of rocks and ages, and with contrasting coverage settings, with arid provinces in the northern region, and intermediate and lush southern provinces. Lineaments were interpreted in an area of more than 52000 km2 in derived products from satellite imagery and DEMs. This dataset produced a high-density directional dataset with attributes including rock age, type and province, in addition to interpretation scale and image source. Dense lineament collection applications on fracture pbkp_rediction, secondary porosity development and tectonic evolution are proposed. Composed lineaments (lineaments of lineaments) are used to compartmentalize Cesar-Rancheria basin, particular fracture intersections are proposed as potential hot spot locations in calcareous rocks and the systematic orientation change of rock age-grouped lineaments is used as additional support for clockwise Perija range rotation.
