Part-II 
Mark-100 
 
1.  Stratigraphy: 
 Principles of Stratigraphy, Stratigraphic Correlation; Stratigraphic outline of Bangladesh and adjoining 
areas. Quaternary geology of the Bengal basin-physical framework and its landforms, distribution of the 
Quaternary deposits. 
 
2. Exploration methods: 
 Widely used methods in exploration like: Seismic method -Importance of seismic  work, geometry of 
seismic wave path, reflection and refraction fi eld methods and equipment, elevation and weathering 
correction of seismic data, velocity, and depth and dip determination by reflection and refraction data 
both for single layer and multi layer, interpretation of seismic sections. Gravity method -introduction, 
earth's gravity field and its variations, reduction of gravity data, gravity instruments, techniques and 
field survey, interpretation of gravity data. Electrical method -elementary theory, effect of 
inhomogeneous ground, electrode configuration, field p rocedure, interpretation of profiling and 
sounding data. 
 
3.  Petroleum Geology: 
 Chemistry of petroleum , formation of oil and gas; generation of hydrocarbon, organic matter in 
sedimentary basins, diagenesis, catagenesis, kerogen composition and classifica tion. Petroleum 
migration and accumulation, primary and secondary migrationas and their mechanism. The traps and 
their classification. The reservoir properties -porosity and permeability, diagenesis with emphasis on 
clay mineral diagenesis, reservoir continuity and reserve estimation. World's major oil provinces; a brief 
account of the petroleum geology of Bangladesh. 
 
4.  Hydrogeology: 
 Origin and occurrence of ground water, rock properties affecting ground water, subsurface distribution 
of groundwater, geo logical formations as aquifers, and types  of aquifers. Ground water movement, 
Darey's law, permeability, transmissibility, tracing of ground water movement, ground water flow lines 
and contours. Ground water exploration, presentation and interpretation of results; determination of 
aquifer characteristics pumping test. Water wells, well design and well development. Ground water 
resources of Bangladesh: Problems and Prospects. 
 
5.  Mineral Resources:  
 Classification of economic mineral deposits; mode of occurrence, controls of ore localisation, formation 
of ore mineral deposits by magmatic and metamorphic processes including magmatic concertration , 
hydrothermal processes, contact metamorphism, metamorphic minerals, submarine, exhalative and 
volcanogenic minerals; Mineral resources of Bangladesh -occurrence, distribution, stratigraphic 
relationship, reserve and uses of gas & oil, coal, peat, limestone, glass sand, white clay, placer deposits, 
hard rocks, building materials and metallic minerals.
