This short course is aimed at the exploration and R&D industry in hydrocarbons and native hydrogen. The course is based on a holistic multidisciplinary approach to mineral systems which aims to understand fluid and mass transfer at a crustal to outcrop scale.
The discovery of hyperextension and mantle exhumation, linked to magmatic systems and serpentinization at rifted margins and slow spreading systems, provides new opportunities but also challenges in exploration. During the latest stages of rifting and initial seafloor spreading, when basins are often restricted and seaways not connected, mantle exhumation, closely linked to hydrothermal systems and magmatic activity have the potential to change: (i) seawater chemistry; (ii) sustain the evolution of primitive life; (iii) control depositional environments and reservoir properties; and (iv) result in massive element-transfer of Si, Mg, Fe, Mn, Ca, Au- Ag, Co, Cu, Zn, Ni and other elements.
This course will review the new tectonic concepts of hyperextension and mantle exhumation using onshore and offshore examples and including seismic, drill hole and field observations. A second part reviews the characteristics of these systems focusing on the link between fluid flow and mass transfer and the tectono-magmatic and sedimentary evolution of these systems.
**This short course is part of the “Structural Geology and Resources 2022” conference in Kalgoorlie.**
