Understanding the structure of deeper parts of the earth is of vital importance to understand the relationship between the processes that have taken place inside it and evolution of various structural / tectonic features present on the Earth's surface. This knowledge also provides insight into the characteristics of the earthquakes, other natural hazards and formation / distribution of the natural resources. The geological efforts to study the Earth, including drilling, are limited to its top few hundred meters but have provided comprehensive knowledge on the material that is of direct socio-economic interest to the human being. During the last four decades huge effort has been put to decipher the velocity and structural configuration of the deeper parts of the earth through controlled source seismic refraction and reflection studies. In this book most of the results obtained through such studies of the continental crust over the Indian subcontinent and its surroundings have been collated and compiled. These results are integrated with other geophysical studies and reinterpreted. The aim is to provide the reader with an easy access and opportunity to understand the structure and tectonics of different geological provinces stretching across Kutch in the west to Bengal in the east and Southern Granulite Terrain in the south to Kashmir/Himachal in the north. /* Style Definitions */ table.MsoNormalTable {mso-style-nameTable Normal; mso-tstyle-rowband-size0; mso-tstyle-colband-size0; mso-style-noshowyes; mso-style-priority99; mso-style-qformatyes; mso-style-parent; mso-padding-alt0mm 5.4pt 0mm 5.4pt; mso-para-margin0mm; mso-para-margin-bottom.0001pt; mso-paginationwidow-orphan; font-size11.0pt; font-familyCalibri,sans-serif; mso-ascii-font-familyCalibri; mso-ascii-theme-fontminor-latin; mso-fareast-font-familyTimes New Roman; mso-fareast-theme-fontminor-fareast; mso-hansi-font-familyCalibri; mso-hansi-theme-fontminor-latin; mso-bidi-font-familyTimes New Roman; mso-bidi-theme-fontminor-bidi;}
