英文摘要: This paper is a comprehensive review of the potential for remote sensing in exploring for geothermal resources. Temperature gradients in the earth crust are typically 25-30{ring operator}C per kilometer depth, howeverin active volcanic areas situated in subduction or rift zones gradients of up to 150{ring operator}C per kilometer depthcan be reached. In such volcanic areas, meteoric water in permeable and porous rocks is heated and hotwater is trapped to form a geothermal reservoir. At the Earth's surface hot springs and fumaroles areevidence of hot geothermal water. In low enthalpy systems the heat can be used for heating/cooling anddrying while in high enthalpy systems energy is generated using hot water or steam. In this paper wereview the potential of remote sensing in the exploration for geothermal resources. We embark from thetraditional suite of geophysical and geochemical prospecting techniques to arrive at parameters at the Earth surface that can be measured by earth observing satellites. Next, we summarize direct and indirectdetection of geothermal potential using alteration mineralogy, temperature anomalies and heat luxes,geobotanical anomalies and Earth surface deformation. A section of this paper is dedicated to publishedremote sensing studies illustrating the principles of mapping: surface deformation, gaseous emissions,mineral mapping, heat flux measurements, temperature mapping and geobotany. In a case study from theLa Pacana caldera (Chili) geothermal field we illustrate the cross cutting relationships between varioussurface manifestations of geothermal reservoirs and how remotely sensed indicators can contribute toexploration. We conclude that although remote sensing of geothermal systems has not reached fullmaturity, there is great potential for integrating these surface measurements in a exploration framework.A number of recommendations for future research result from our analysis of geothermal systems and thepresent contributions of remote sensing to studying these systems. These are grouped along a number ofquestion lines: 'how reproducible are remote sensing products', 'can long term monitoring of geothermalsystems be achieved' and 'do surface manifestations link to subsurface features'? © 2014 Elsevier B.V.
