Sedimentology involves the study of physical properties of particles/sediments that form sedimentary rocks. Physical characteristics of particles in terms of textures and composition form the basis of understanding the origin of the particles, sedimentation process, formation of different sedimentary rocks and the variations in sedimentary structures. This course is designed to teach the particle framework and processes that form different sedimentary rocks and sedimentary structures.
This course deals with the study of prehistoric animals and their remains buried and preserved in sedimentary rock, or trapped in organic matter. Systematic palaeontology is studied to understand the age and the environment in which fossils form within their host rocks. The course could enable scientists to trace the evolutionary history of extinct as well as living organisms. Using detailed information on how fossils are distributed in layers of rock, geologic maps, which are essential in the search for oil, water, and minerals could be prepared.
