Characteristics of Sedimentary Rocks — Subsurface Geological Mapping and Computer Software Data Management Systems

Field geology seeks to describe and explain the surface features and underground structures of the lithosphere. Subsurface geology can be obtained from surface observation, vegetation trends, drainage, geophysical studies, air photographs, satellite imagery. Reading and interpretive the subsurface geology from surficial clues is like reading a mystery book. It pertains to the study of rock relationships by the use of data obtained from the surface sources as well as test drilling and underground mines, and quarries.
