My interests center on the Earths temperature field at lithospheric scale. Parameters of interest are the terrestrial heat flow, the generation of radiogenic heat in the crust and the thermal properties of rocks, such as thermal conductivity and thermal diffusivity. This expertise also is implemented in the exploration of natural geo-energy resources for which the thermal field is characterized at regional as well as local scale. For this purpose geological data from boreholes and surface geophysical surveys as well as data from laboratory studies of rock chemistry and physics are implemented in numerical, geology-assisted subsurface models. Work performed in the past was concentrated on different geodynamic settings in the world, e.g. the North German Basin, the Erzgebirge and Luxembourg in Europe, the North American Midcontinent, the Andean subduction zone in Bolivia and Chile, the Arabian Shield in Israel and Jordan, as well as regions of the Indian continent.

The Ph.D. also involved an in depth look at global patterns of heat loss and hydrothermal circulation through the oceanic lithosphere. He then began a postdoc as a Green's Scholar at Scripps Institution of Oceanography and built an apparatus to measure electrical conductivity at elevated temperatures while continuing to look at heat flow variations at the ocean-continent transistion. His on-going research includes connection to the previous heat flow studies and also new directions involving the interpretation of electrical conductivity variations within the mantle in terms of composition, melts, and volitiles such as water and carbon dioxide.

Geology Department, Earth Sciences Division, rnegrete73@yahoo.com

Originally involved with the magmatic evolution of volcanic systems, my research interest switched to use thermal processes to understand various geologic processes that involve the transfer of energy. Since heat (energy) and temperature are fundamental to many earth processes, being able to quantify the flow of energy and thermal budgets leads to an appreciation and understanding of Earth dynamics. My research approach focuses on marine heat flow and the modeling of terrestrial processes that involve the thermal state of the lithosphere and its role in influencing geodynamics. There are many fundamental processes that influence and are influenced by heat transport (i.e., thermal evolution of the oceanic crust and lithosphere, geodynamics of plate boundaries, fluid circulation and associated impacts on water-rock interactions, seismicity, tectonics and magmatism) Understanding these processes involve the quantification of energy and fluid fluxes, requiring knowledge of the thermal state deduced from direct observations that include, heat flow, sub-bottom temperature and rock properties.
