The evolution, geometry and structural framework comprehension of intrusive granitic rocks is fundamental to enhance and provide subsidies of ore-related occurrences in the Sulriograndense shield, Rio Grande do Sul state, Brazil. This known and complex mineral province is formed in the Archean to neo/Paleoproterozoic presenting igneous, metamorphic, and sedimentary rocks. The present study main objective was to detect and delineate unknown surface. The present study main objective was to detected and delineat unknown surface mapped features. Such discontinuties and structures are related to structural and lithologic limits in the granitic batholith known as Suíte Granítica Caçapava do Sul (SGCS) (Caçapava do Sul Granitic Suite). Aeromagnetic data, processing and enhancement techniques was applied to delineate linear features and define magnetic domains. Additionally, Euler Deconvolution was performed in order to determine magnetic detected sources estimated depth. The results, were integrated to previous geologic basis (mapping) using GIS and allowed to improve and better understand the structures and framework in a deeper context. These preliminary contributions offers important subsidies in a regional-scale context. Provides, also, structures related detected anomalies for further geophysical local-scale surveys in order to maximize the understanding of the CGCS limits in depth and also nearby host rocks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
