Nathan Daczko

Biography

BSc (Computer Science), University of Sydney PhD (Geology), University of Sydney Associate Professor Nathan Daczko is a metamorphic petrologist who combines field and laboratory studies to examine metamorphic processes. He addresses multiple scales, from microstructure to the evolution of large orogens. Inverting this information provides constraints on the geodynamic and metasomatic processes involved in the history of metamorphic rocks, and advances understanding of crustal evolution and geodynamics. Current research is focused on the microstructural and microchemical changes that occur during melt-rock interaction. This research crosses discipline boundaries to explore igneous/structural mechanisms of melt migration and metamorphic processes of melt-rock reaction that might track the pathways. This topic is also explored using high-P and high-T experiments of melt-rock interaction. The field aspects of the research explore the exposed lower crustal plumbing systems of ancient magmatic arcs, such as Fiordland, New Zealand, to better understand how mass transfer occurs through the deep crust and what signature this leaves in the rock record. Related research examines melt migration and melt-rock interaction in the exposed roots of other tectonic settings, such as (i) an intracontinental orogen, exposed in Central Australia, (ii) an extensional period of the New England Orogen, and (iii) poorly-defined orogenic systems now exposed by recent uplift in the Italian Alps (Ivrea-Verbano Zone).

Research Interest

Fields of research interest include: (i) structural geology, tectonics and microstructure, (ii) metamorphic petrology and thermobarometry, (iii) evolution of plate boundary zones, (iv) integration of geological and geophysical data, (v) geochronology, and (vi) field mapping.
