Thermal springs and geysers are the surface manifestations of earth’s inner heat content. Heat energy in the form of subsurface steam, hot water, heated rocks and associatedminerals andgas products is consideredasgeothermal energy. This book presents a comprehensive overview of the nature of manifestation and general aspects of thermal springs of Odisha. Detailed description on geological formations and relationship between tectonic settings with thermal spring manifestation is given for better understanding of the geothermal system. Regional geological mapping indicates that the thermal springs of Odisha are mainly confined to crystalline schists andgneissic terrains of Precambrian period. The thermal springs are located within charnockites, khondalites, augen gneiss and mafic granulites belonging to Eastern Ghats Supergroup or quartzites/quartz schists and metapelites of Iron Ore Supergroup or within Vindhyan Supergroup of rocks. The chemical analyses indicate that the spring waters are not identical to one another in their chemical characters. They are categorized mainly under three types, i.e. (i) sodium chloride (NaCl) type, (ii) sodium bicarbonate (NaHCO3) type and (iii) calcium bicarbonate (CaHCO3) type. Physico-chemical characteristics of water, as well as gas, have been studied and interpreted to ascertain the nature and source of geothermal fluid and to generate a conceptual model on the origin. The thermal springs of Odisha are considered to be of meteoric origin and the heat source may be derived from geothermal gradient, disintegration of radioactive elements or from the exothermic reactions during metamorphism. Thermal springs of Odisha belong to low enthalpy geothermal category and hence, their utilization potential is restricted to direct or non-electrical application fields mainly for balneology or therapeutic use, space heating, greenhouse culti￾vation, industrial applications, mineral water bottling, etc. Rapid depletion of conventional energy resources has demonstrated thatthere is an urgent need for exploration of resources to meet the ever-increasing demand for energy. Geothermal energy yet largely untapped is a significant non-conventional source of energy which can be used without polluting the environment in the present state of scientific and technical knowledge.

Various research and academic institutions have started preliminary and, in some cases, detailed investigations of geothermal fields in order to examine the possibility of suitable utilization of the thermal springs of India. This energy is practically perennial, inexhaustible, pollution free and eco-friendly. A holistic approach would certainly bring awareness about the importance of this energy and protection of its quality and quantity would certainly help in conser�vation andpropermanagement ofthis resource.Infact,explorationandexploitation of this energy can open up new vistas in the direction offuture energy requirements of the nation. The book will be a useful reference for the earth scientists, planners and researchers in the field of geothermal energy. Besides, as the thermal springs are spectacular sites for tourists,the book can also help the tourists,tourist guides and tourism departments.Ihave tried my besttoacknowledge all sources of information andviews of original authors and workers. Though care has been taken, some might have left unintentionally and I welcome such omission, so that they can be rectified in future. This book is an outcome of my association with Prof. S. Acharya, Former Vice-Chancellor and Head, P.G. Department of Geology, Utkal University, Bhubaneswar, India. I express my deep sense of gratitude to him for his guidance and valuable suggestions. I am very much grateful to Prof. P. P. Singh, Emeritus Professor, P.G. Department of Geology, Utkal University, Bhubaneswar, India for his inspiration for writing this book. I am extremely thankful to Dr. P. C. Naik, my colleague for his academic criticisms which are of great help in structuring this book.
