Introduction of Geology
Definition of Geology, Engineering Geology. Importance of geology from Civil
Engineering point of view. Importance of physical geology, petrology and
structural geology. Case studies of failures of few civil engineering
constructions, weathering of rocks and its effect on the properties of rocks,
importance of weathering with reference to dams, reservoirs and tunnels.
Earth structure- Lithosphere- Internal structure of the earth, Plate Tectonics.
Definition of mineral, mineralogy, Importance of study of minerals: rock
forming and ore forming minerals. Different methods of study of minerals.
Study of minerals by physical identification method and their physical
properties. Determination of Physical properties of following minerals:
Feldspar, Quartz, Flint, Jasper, Olivine, Augite, Hornblende, Muscovite,
Biotite, Asbestos, Chlorite, Kyanite, Garnet, Talc, Calcite. Study of ore
forming minerals such as Pyrite, Hematite, Magnetite, Amethyst, Galena,
Pyrolusite, Graphite, Magnetite, and Bauxite, Coral reefs.
Definition of a rock, petrology. Classification of rocks-Geological
classification of rocks. Rock Cycle. Classification of igneous Forms, structures
and textures of igneous rocks. Classification of sedimentary rocks, and its
structures and textures. Classification of metamorphic rocks, its structures
Megascopic Study of Granite, Dolerite, Basalt, Pegmatite, Charnockite,
Sandstone, Shale, Limestone, Gneiss, Schist, Quartzite, Marble and Slate.
Out Crop, Study of geological structures associated with rocks such as
joints, unconformities-their import
ant types. Significance of Strike
and dip in geological structures, shield areas and seismic belts, seismic
waves, Richter scale, Precautions to be taken for building construction in
seismic areas, Ground Water, water table, common types of ground water,
springs, geological controls of ground water movement, ground water
Geology of Dams, Reservoir and Tunnel
Types of Dams, Importance of geological considerations in the site
selection of dams, reservoirs and tunnels. Case histories of dams,
geological factors affecting the water tightness and life of a reservoir.
Purpose of tunnelling, types of tunnels, over break, lining of tunnels.
Geographical physical aspects of earthquake, tsunamis, avalanches,
forest fires, hurricanes, tornadoes, volcanic eruptions, coastal
erosion, ice jams, liquefaction, geyser deposit, sinkholes and
landslides. Disaster prevention mitigation and management.
