Stages of rock deformation. Construction of block diagrams.Sterographic and equal area nets.Solultions of simple problems by stereographic net. Topographic maps and their interpretation. Use of clinometers compass in the field Measurements of bed, foliation, folds joints faults and lineations in the field. Principles of geological mapping. Effect of topography on outcrops Drawing of sections.
Part-II
(a) Crystallography: Elements of crystal structure. Laws of crystallography, Symmetry elements of normal classes of seven crystal systems.
Properties and interaction of light and crystalline matter.Petrological microscope and accessories Construction and use of Nicoleprism.Pleochroism, double refraction, extinction angle, birefringence and twinning in crystals, isotropic, uniazial and biaxial minerals
