Rocks are used in the formation of foundation or base of civil engineering projects, because the rocks are more
stable and having high strength (1). The branch of geology that deals with application of GEOLOGICAL knowledge to
civil engineering projects is known as geological engineering or engineering geology (2). Engineering geologists are
needed wherever an understanding of rock properties and geological structures is required, i.e. road construction,
building foundations, dam construction etc (3). The LOCAL geology of an AREA is important when planning a major
construction (4). The geology of an area represents the location and nature of any civil engineering structures (5).
Natural hazards (earthquake, landslide, and tsunami) are originated and produce the deformation on surface of earth.
Natural hazards cannot be prevented, but its prediction is determining (6).
Different type of rocks &there uses: Rocks are the naturally solid aggregate of minerals (7). Since the crust of the
earth is composed of rocks, a rock may be defined as a unit of the earth crust (8). Minerals are only responsible for
the formation of rocks (9).civil engineers need to know the properties of rocks, to many type of rocks for used many
purpose (as foundation rock, as building STONE, as road rock or metal etc) (10). Petrology is the branch of geology
which deals the study of rocks such as formation, classification, and occurrence (11). There are three types of rocks
on the basis of their origination.
