PRESURVEY STUDIES AND 2D SURVEY DESIGN 2.1 PRESURVEY STUDIES Pre- survey studies are essential for effective data acquisition in order to meet exploration objectives in the survey area. Before the start of any data acquisition project, a database is to be built up regarding the area. A. Formation of data base: i. Geological and seismo -geological objectives of the survey should be clearly known. ii. To collect geological map of the area depicting all the relevant geological information and to study details of exposures, surface dips and surface tectonic features. iii. To collect satellite images of the area. iv. To collect time structure maps of the target zones and to study the major structural aspects, fault patterns and their position and other sub surface tectonic activity. v. T...
