GENERAL GEOLOGY

Detailed explanation-1: -Lithostratigraphy is a sub-discipline of stratigraphy, the geological science associated with the study of strata or rock layers. Major focuses include geochronology, comparative geology, and petrology.

Detailed explanation-2: -Lithostratigraphy is the ‘classification of bodies of rock based on the observable lithological properties of the strata and their relative stratigraphic positions’1. Stratigraphy includes information about processes, geographical distributions, and the palaeo-environment of past glaciers and glaciation.

Detailed explanation-3: -Whereas lithostratigraphic classification is possible for any body of rock, biostratigraphic classification is possible only for fossiliferous rocks that bear identifiable fossils.

Detailed explanation-4: -Lithostratigraphic units are bodies of rocks, bedded or unbedded, that are defined and characterized on the basis of their observable lithologic properties.

Detailed explanation-5: -Lithostratigraphic unit A lithostratigraphic unit may consist of sedimentary, or igneous, or metamorphic rocks. Lithostratigraphic units are defined and recognized by observable physical features and not by their inferred age, the time span they represent, inferred geologic history, or manner of formation.
