Clastic Dykes Paraná Basin

3D Model

This is a 3D model of a rocky outcrop of the Corumbataí Formation (Permian, Paraná Basin, Brazil), where pelitic layers (claystones and siltstones) are cut by a swarm of clastic dikes. We used this model to compare the structural information (geological attitude, thickness) from the 3D models with data collected in the field using traditional tools (geological compass, measuring tape). This model, with 500.000 faces, is a simplified version of the original one, which has over 3.000.000 faces.
