Unit wise Distribution of Course contents:
Unit-1 Petrology:
Rocks, its definition and types (igneous, sedimentary and
metamorphic), their distinguishing characters.
1)
Igneous: Its definition and composition, Forms of
igneous rock. Differentiation of magma. Texture and structure of igneous rock.
Texture (Porphyritic, Poikilitic, Ophitic, Coarse, Fine and Glassy). Structure
(columnar, flow, pillow, vesicular, sheet, amygdaloidal). Classification of igneous
rocks on the basis of texture, mineralogical composition and color. Study of
the following rocks with respect to their mineralogical composition and
texture:-Granite, Pegmatite, Rhyolite, Gabbro, Dolerite, Basalt.
2)
Sedimentary: Texture and structure of sedimentary
rocks. Processes of formation of sedimentary rocks. Study of the following
rocks: - Conglomerate, Grit, Sandstone, Shale, Lime stone.
3)
Metamorphic: Definition, agents and types of
metamorphism. Depth zones of metamorphism (epizone, mesozone, katazone). Study
of the following rocks with respect to their mineralogical composition and
texture and structure: - Schist, Gneiss, Marble, Slate and Quartzite.
Unit-2: Indian Stratigraphy:
Precambrian and Mesozoic stratigraphy of N.E. India. Precambrian
of Kamataka and Vindhyan. An outline of the tertiary stratigraphy of the N.E.
with emphasis on its lithology, paleontology and economic importance.
Unit-3: Economic Geology:
Definition of ore. Elementary idea of the processes of formation
of mineral deposits. Origin and mode of occurrence of coal and petroleum. Mode
of occurrence, distribution in India and uses of the following in the N.E. -
Coal, Petroleum, Silliminite, Limestone.
Unit-4: Ground Water and Engineering Geology:
Ground Water: Definition,
elementary idea of hydrologic cycle, porosity, permeability, aquifers, water
table.
Engineering geology: Selection
of bridge site and Dam site, Flood- its geological causes, prevention with a
view to proper utility.
Unit-5: PALEONTOLOGY:
Fossil: Definition,
mode of preservation, uses. An outline of the important forms of life (plant
and animal) through geological ages. A brief morphological study of the
phylum/class Brachiopoda, Lamellibranchia and Gastropoda.
