Core Understanding – Core Description and Lithostratigraphy
The shipboard sedimentologists are responsible for describing the lithology and stratigraphy of sediments and sedimentary rocks that are recovered by scientific ocean drilling. Lithology is the set of physical characteristics of the rock or sediment. Stratigraphy is a term that refers to the classification, nomenclature (naming), and interpretation of layered rocks and sediment.
