lithostratigraphy

The basic descriptive three-dimensional sedimentary rock elements that record in terms of their lithology, biota, and other related characteristics, a specific depositional setting or event and can be interpreted in terms of water depth, depositional energy, and sediment supply/biologic input are lithofacies. Example of lithofacies include wackestones-mudstone, sandstone, etc., (Kerans & Tinker, 1997).

Thus lithofacies are used to interpret, correlate, and map sedimentary rocks whether the approach is lithostratigraphic or allostratigraphic.
