3D Geological Modelling of Igneous Intrusions Based on Emplacement Mechanisms

This thesis proposed a method to build 3D geological models of igneous intrusions using our current understanding of intrusion systems. Geological models allow the subsurface’s geology to be evaluated, and they are used for a wide range of applications, from research investigation to management of natural resources. The method proposed in this work is applied to investigate the geology of two intrusions systems: the Jurassic dolerite in the Hobart region and Mesozoic plutonic complexes in northern Chile. The results of both applications allowed us to understand better the emplacement processes that led to the formation of both intrusions systems.
