Course outline:

  • Introduction
    Origin and development
  • Geologic Mapping and Remote Sensing
    Topographic maps, geologic maps, preparation of geologic sections, aerial photographs, LIDAR, SAR, GIS
  • Mineralogy
    Chemical analysis of rocks and minerals, rock and soil minerals, physical properties of minerals, susceptibility of minerals to alteration, basics of optical mineralogy, SEM, XRD
  • Classification of Soil and Rock
    Types of rock and origin: Igneous (extrusive and intrusive), sedimentary and metamorphic, ternary diagrams, definitions (structure, texture)
  • Igneous Rock
    Agents, structure, texture, IUGG classification of intrusive and extrusive rocks
  • Metamorphic Rock
    Causes of metamorphism (stress, temperature, tectonism, pore fluid), recrystallization, phase change, structure and texture
  • Sedimentary Rock
    Sedimentation environments, structure, textural classification of siliclastic and carbonate rock
  • Soil Formation
    Weathering processes, transportation and sedimentation processes, structure, texture and classification, surficial deposits and landforms
  • Subsurface exploration
    Intrusive and non intrusive sub-surface investigation, drilling and sampling, geophysical methods, geologic investigations for site selection of dams, reservoirs, tunnels, bridges and highways
  • Engineering Properties of Soil and Rock
    Engineering properties (density, unit weight, porosity), strength, index measurements for soil and rock (SPT blow count, RQD, RMR, Point Load Index), relationships of index measurements with strength of soil and rock.
  • Strength Behavior of Soil and Rock
    Stress and strain in rock, Mohr’s Circle, concept of effective stress, failure of soil and rock, fracturing of rock, folds, faults and joints in rock, shear failure of soil and rock, consequences of failure (landslides, earthquakes, subsidence)
  • Subsurface water
    Sources, aquifer, aquiclude, water table, Artesian groundwater in soil and rock, springs, hydraulic conductivity and its measurement, Darcy’s law, well hydraulics, well yield, water capacity of rock, lowering of water table and subsidence, salt water intrusion in coastal areas
  • Geologic and seismotectonic setting of India
    Geologic provinces of India and their surficial and subsurface geology, seismotectonics of the Indian plate, seismic zones of India
  • Geological Hazards
    Major geological hazards Geological considerations in design of constructed facilities and infrastructure, causes and classification of landslides, stability assessment for soil and rock slopes, mitigation of landslide hazard, effect of earthquakes on constructed facilities and infrastructure, geotechnical and structural considerations in mitigation of earthquake hazard
