WebOct 2, 2024 · Absolute dating, methods that produce specific chronological dates for objects and occupations, was not available to archaeology until well into the 20th century. Stratigraphy and the Law of Superposition Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. WebSteno's laws of stratigraphy describe the patterns in which rock layers are deposited. The four laws are the law of superposition, law of original horizontality, law of cross-cutting relationships, and law of lateral continuity. Nicolaus Steno was a …
