Definitions• Stratigraphy:  The science of studying rock layers,

or strata.  It is concerned with all characters and attributes of rocks as strata, the order in which they were formed, and the matching, or correlation, of similar strata between different locations.

• Lithostratigraphy:  The part of stratigraphy that organizes rocks into units (formations), and correlates rocks between different locations, based on their  lithology.
