"Mapping rocks"

Geology
Geology is the study of the different planets (emphasis placed on earth) and how they works; it investigates processes that operate at and below the surface of the Earth, and the materials in which these processes occur. Geology examines the historical record of geological events preserved in the rock record, in the mountains or oceans; it also explores geological resources in our everyday lives. Geology attracts people who love the outdoors and thrive on practical challenges. In addition to a basic field component, the earth sciences employ much of the sophistication of chemistry, physics and engineering to interpret the nature, origin and usefulness of minerals, rocks, soils, oceans, groundwater and atmosphere.

In order to understand the geological maps, we need to understand the environment that existed in the beginning of life and compare it to today's geological-atmospheric-landscape environment.


Objectives of the Project
A geological map is a special-purpose map made to show geological features like:

  • Rock units or geological strata are shown by colour or symbols to indicate where they are exposed at the surface.
  • Bedding planes and structural features such as faults, folds, foliations, and lineations are shown with strike and dip or trend and plunge symbols which give these features three-dimensional orientations.
  • Stratigraphic contour lines may be used to illustrate the surface of a selected stratum illustrating the subsurface topographic trends of the strata. Isopach maps detail the variations in thickness of stratigraphic units.
