Contribution to Tectonic studies involving the integration of structural, metamorphic and chronologic datasets:
Investigation of orogenic belts by Integrated Terrane Analysis: characterization of component terranes using an integrated suite of metamorphic - deformation - chronology - intrusive - stratigraphic datasets to constrain tectonic evolution. Combination of both metamorphic and structural expertise has resulted in integrated studies that have made significant contributions on the tectonic evolution and crustal processes operating within orogenic systems; specifically the Himalayan Metamorphic Front (Goscombe & Hand, 2000, Goscombe et al., 2006), Arunta Inlier (Goscombe, 1991, 1992a,b,c), the transpressional Kaoko Belt (Goscombe et al., 2003a,b, 2005, 2006), Damara Orogen (Goscombe et al., 2004), Zambezi Belt (Goscombe et al., 1994, 1998, 2000), Mozambique Belt (Goscombe et al. 2003c), Mid-ocean ridge processes and Indo-Australian/Pacific plate margin (Goscombe & Everard, 1999, 2001) and NE Tasmania (Goscombe et al., 1994). Work in the Kaoko Belt has been able to document the 3D structure of the entire Kaoko Belt and recognised lower-crustal lateral extrusion in this transpressional system (Goscombe et al., 2005, 2006). Models for gold-mineralization in the east Yilgarn Craton have been developed, that involve the inter-relationship between thermal, barometric, intrusive, fluid and deformation evolution in different parts of the craton (Goscombe et al., 2007).
