Measuring surface heat flow at the Hikurangi Trough is key toward characterizing the local thermal regime and the influence of thermally sensitive processes such as fluid flow and slow slip. Marine heat flow data were collected during May– June 2015 in the northern Hikurangi Trough at sites seaward and landward of the deformation front, giving mean and one standard deviation values of 58 ± 16 and 46 ± 15 mW m−2 respectively. A 3.5 m violin-bow style probe was used to measure thermal conductivity and temperature gradient of the seafloor, and heat flow is calculated using Fourier’s law. Two-dimensional steady-state, finite element modeling was undertaken to analyze the influence of subduction parameters on surface heat flow and temperature along the subduction thrust. Heat flow values seaward of the deformation front have been found to be sensitive to the structure of buried and outcropping extrusive crust, but the mean heat flow is within the range of expected values for lithosphere this age (120 Myr) according to the GDH1 cooling model. Landward of the deformation front, measured heat flow is in excess of preferred modeled values. I interpret these observations as evidence for fluid flow within a crustal aquifer system and through splay faults within the forearc. A heat flow discontinuity of 40 mW m−2 landward of the deformation front supports the presence of compaction sourced fluid along the subduction thrust, which is consistent with previous evidence for excess pore pressure and the occurrence of shallow slow slip.

Heat provides the energy that drives almost all geological phenomena and sets the temperature at which these phenomena operate. This book explains the key physical principles of heat transport with simple physical arguments and scaling laws that allow quantitative evaluation of heat flux and cooling conditions in a variety of geological settings and systems. The thermal structure and evolution of magma reservoirs, the crust, the lithosphere and the mantle of the Earth are reviewed within the context of plate tectonics and mantle convection - illustrating how theoretical arguments can be combined with field and laboratory data to arrive at accurate interpretations of geological observations. Appendices contain data on the thermal properties of rocks, surface heat flux measurements and rates of radiogenic heat production. This book can be used for advanced courses in geophysics, geodynamics and magmatic processes, and is a reference for researchers in geoscience, environmental science, physics, engineering and fluid dynamics.

Thermal Signatures Of Heat Transfer Processes In The Earth S Crust written by Christoph Clauser and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2006-04-10 with Science categories.
This book deals with the signatures left by geodynamic proceses in the temperature field of the Earth's crust. First, it introduces briefly the established, indirect methods for interpreting the present termperature field and methods for reconstructing the thermal fields of the geological past. Then the spatial and temporal scales that are relevant for heat transport processes are described. This problem is discussed both theoretically and on the basis of data from the German Continental Deep Drilling Program (KTB). The climate of the last 200 years and the postglacial warming in central Europe are reconstructed on the basis of two sets of temperature data from shallow and deep boreholes. This book is written for an audience at an advanced undergraduate or graduate level with an understanding of basic physical principles. It avoids particular terminology, and special terms are introduced.

Terrestrial Heat Flow and the Lithosphere Structure summarizes current problems of analyzing related data. The individual chapters are written by leading scientists in geothermics, and are arranged in three sections: - General Lithospheric Geothermics - Regional Lithospheric Geothermics - Worldwide Heat Flow Density Studies. Emphasis is laid on the interrelations between lithospheric structure and local heat flow fields.

In steep terrain the effect of advective flow can be significant, as it can distort the temperature field in the upper brittle crust. The effect was studied by modeling advective flow across a large valley system in Tibet which is associated with several geothermal hot spring systems, the Yanbajing Valley. It was found that, in this setting, all near-surface temperature gradients are significantly disturbed, attaining values differing by up to half an order of magnitude from those resulting from conductive heat transfer. Allowing for advective effects, it was found that the crustal heat flux within the Himalayan Geothermal Belt lies within the range of 60 to 90 mW/m2 in the Lhasa-Yanbajing area.

This book, now in its second edition, offers a comprehensive and modern treatment on the background knowledge of heat transfer processes in the lithosphere. In the light of the success of the first edition, several chapters of the book have been revised and the book has been enriched with a new chapter on geothermal methods used for the inference of past climate changes.The book starts with a brief review of global tectonics and of the structure of the crust and upper mantle. Then the theory of heat conduction as well as the thermal properties and the methods for the determination of thermal conductivity and radiogenic heat are introduced. Subsequently the geothermal flow and the thermal state of the lithosphere and deep interior are analyzed. The formation, upwelling mechanisms, solidification and cooling of magmas, which can be a fundamental heat source in many geothermal systems, are reviewed. Analytical methods used for gaining information on heat and groundwater flow from the analyses of temperature depth data are also covered. Data and practical examples are supplied to facilitate the understanding of the different topics.The book is intended for Earth science graduate students and researchers.

The outflow of heat from the earth's interior, the terrestrial heat flow, and the temperature field at depth are determined by deep-seated tectonic processes. The knowledge of the re gional heat flow pattern is thus very important in geophysics and provides a useful tool for studying crustal and litho spheric structure and understanding the nature of their evo lution. In order to use the results of heat flow measurements for regional studies and/or to correlate the observed surface geothermal activity with other geophysical or geological fea tures, a map showing the surface distribution of heat flow is necessary. Since 1963, when the first comprehensive listing of all available heat flow data appeared (Lee, 1963), several at tempts have been made to up-date the list, to classify all the data and to interpret them with respect to tectonics, deep structure and to use them for constructing surface heat flow maps. The first listing was subsequently revised by Lee and Uyeda (1965); numerous new data which were published there after were included in successive catalogs compiled by Simmons and Horai (1968) and then again by Jessop et al. (1976). The map showing the surface heat flow pattern may also be of great value for practical purposes, in view of the recent world-wide search for applicable sources of geothermal energy.
