The term chronostratigraphy refers to that aspect of the field of stratigraphy dealing with temporal (time) relations and ages of rock bodies. Chronostratigraphic classification in the field of stratigraphy organizes rocks on the basis of their age or...

The term bedding (also called stratification) ordinarily describes the layering that occurs in sedimentary rocks and sometimes the layering found in metamorphic rock. Bedding may occur when one distinctly different layer of sediment is deposited on an...

Stratigraphy is that subarea of geology that treats the description, correlation, and interpretation of stratified Earth materials. Typically, geologists consider stratified Earth materials as layers of sediment or sedimentary rock. This definition,...

Geomorphic investigations were conducted at 13HA385 in 1997, 1998, and 1999 (corresponding with the Phase I-III archaeological investigations). The primary goal of these investigations was to place the site's archaeological record in a geologic context. Soils and stratigraphic units were defined and described, and...
