Abstract

Spatial arrangement regards the spatial position of brittle structures. Even though they are important for several industrial applications, quantification of their spatial arrangement remains a challenge. In this contribution, we quantify and compare the spatial arrangement of regional lineaments and deformation bands in the Eastern Araripe Basin, NE Brazil using the normalized correlation count method on topographic, aeromagnetic, and outcrop data. We have noticed irregular and random arrangements of topographic and aeromagnetic clusters of lineaments, while deformation bands are grouped. The use of topographic and aeromagnetic data represents a reliable way to investigate regions with limitations (topographic, climatic, or social) that make field data hard or impossible to acquire. Furthermore, we proposed a preliminary tectonic evolution model for the eastern border of the Araripe Basin.
