Overview:

The geological architecture and associated mineral resources in eastern Australia are largely obscured by post-Carboniferous sedimentary and volcanic cover. This poses serious challenges towards the understanding of the tectonic evolution of Phanerozoic Australia as well as the ability to find new resources undercover.

Over the past decade, 3D geological modelling has become a fundamental tool to better understand the architecture and unravel the mineral potential of buried terranes.

Recently, the Geological Survey of NSW has developed a series of interlocking 3D models of orogenic provinces, basins, major faults and thickness of post-Carboniferous cover across the state. Constraining datasets for the construction of the 3D models include surface geological mapping, geological cross-sections, well data, digital elevation models, seismic, gravity and magnetic data and 2D forward models. These synthetic 3D models consolidated the available geological datasets and refined the existing interpretations. The NSW 3D Models also establish a fundamental state-wide geological framework that will provide context for future 3D models and geological surveys.

3D modelling is now within everyone's reach. The fact that prospective rocks lie, for the most part, untested beneath cover creates a tremendous opportunity for better prediction and exploration strategies using the latest advances and technologies. The rapid development 3D geological modelling tools as well as increased computing power allow geologists to take a more robust, holistic scientific approach to geological investigation, mining exploration, project design and quantitative resource estimation.

 

Bio:

iovanni is an experienced geophysicist with project management background. His expertise includes processing and interpretation of geological and geophysical data, 3D modelling & inversion and large data management for mineral exploration, resource evaluation and targeting.

Giovanni completed a PhD at Monash University that contributed to a better understanding of plate architecture and evolution of the transition between Proterozoic Australia and the eastern margin of Gondwana, with a focus on the southern Mount Isa terrane and the central Thomson Orogen in Queensland.

Before joining CSIRO, Giovanni worked as a senior geoscientist and 3D modeler at the Geological Survey of NSW, building 2D and 3D geological and structural models of tectonic provinces, basins and sites of interest, and working with geologists to ground truth them in order to improve/update geological interpretations. He has worked at a range of scales, modelling shallow features in regolith, as well as deep crustal-scale features. His current role at CSIRO will contribute to create new knowledge and methods in the field of 3D geological modelling through an integrated approach, developing new technologies to mitigate 3D geological risk in resources management and support industry programs for Exploration Through Cover and Orebody Knowledge
