GENERAL GEOLOGY

Detailed explanation-1: -Stratigraphy: The climatic and geological changes including tectonic events in the geological past can also be known from these investigations. This kind of study of the earth’s history through the sedimentary rock is called historical geology.

Detailed explanation-2: -Stratigraphy is a branch of Geology and the Earth Sciences that deals with the arrangement and succession of strata, or layers, as well as the origin, composition and distribution of these geological strata. The study of archaeological and natural stratification therefore involves the assessment of TIME and SPACE.

Detailed explanation-3: -stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale. It provides a basis for historical geology, and its principles and methods have found application in such fields as petroleum geology and archaeology.

Detailed explanation-4: -Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age).

Detailed explanation-5: -Paleontology and Stratigraphy is a basic subject in the study field of geology. It emphases and assigns relative ages of rock strata by using the shapes, structures, ecology and classification and evolution of fossil assemblages contained within them.
