Evidence for Geology - The Mohenjo-Daro

Question 1
a) Metamorphic rocks because they are hard and strong and
highly weather resistant rocks.
b) Rocks like metamorphic, igneous and sedimentary rocks may
occur at site, all of these may cause problems while
excavation or during bore tests for checking soil properties.
c) Three examples of geological activity that are evident at the
site are mentioned below:
a. The Mohenjo-Daro is the evidence for geology site
because it is ancient place dig by geologists only.
b. Harappa is an evidence place because
c. Taxila is an evidence place because
d. Fossils dig by the geologists is also an evidence, which
tells us about past.
d) Hydrological forces are subject of investigation and
engineering the landscape visibility is also one of that
process in which due to water cycle process landscape
occurs.
e) Fault infill suggests that as they are filled by soil, it decreases
the turbulence for site.
f) As earthquake comes on the plates of rock moves, the
movement also occurs between the sides of the fault.
g) They are sedimentary rocks, formed when mineral particles,
fragmented rock particles are transported by wind, water or
ice.
h) It causes rock disintegration by breaking, grinding, crushing,
they are going to expand and contract possibly cause
structural deterioration.
i) Micro-diorites are the types of igneous rocks, they are formed
when magma (melten matter) cools sufficiently to solidify.

Question 2
a) The intrusive and extrusive events evident in the area are:
a. Intrusive: Granite, Diorite
b. Extrusive: Phyllite, sandstone, shale, mudstone.
b) Two unconformities evident in the area are:
a. Mica Schist; and
b. Gnesis.
c) Structural geological process evident from the map is that
the process of fault occurs in the map.
d) Metamorphic processes appear that the process of low-grade
metamorphism takes place.
e) In the north-west side does the metamorphic grade increases.
f) The difference in the sedimentary rock-type to the north of
the map suggests that they are the top of the surface.
g) The approximate strike of the dipping layers is 120degree.
h) The sequence of geological events that may have occurred in
this area are firstly shale, slate and mudstone moves, then
gradually granite and diorite moves at a slow place.

Question 3
a)
a. Coefficient of uniformity
Coefficient of curvature

b. Sample is not well graded
c. Well-graded soil is very essential for projects of
geotechnical engineering because there is no void in
this type of soil and is water impermeable soil.
