Absolute Dating
Absolute dating provides a computed numerical age in contrast with relative dating which provides only an order of events
Relative Dating
is the science determining the relative order of past events, without necessarily determining their absolute age
Absoute Dating Types
Potassium / Argon Argon / Argon OSL - Optical Radiocarbon Dating Dendrochronology -tree rings
Relative Dating types
Seriation
Cross Dating
Stratigraphy
OSL dating
Optical dating is a method of determining how long ago minerals were last exposed to daylight.
Potassium / Argon dating
is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).
Argon / Argon
a radiometric dating method invented to supersede potassium-argon (K/Ar) dating in accuracy. The older method required two samples for dating while the newer method requires only one.
Radiocarbon Dating
a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years
Dendrochronology
the scientific method of dating based on the analysis of patterns of tree rings, also known as growth rings
Seriation
a relative dating method in which assemblages or artifacts from numerous sites, in the same culture, are placed in chronological order.
Cross Dating
a technique that ensures each individual tree ring is assigned its exact year of formation.
Stratigraphy
a branch of geology which studies rock layers and layering (stratification)
Archeology
the study of human activity in the past, primarily through the recovery and analysis of the material culture and environmental data that they have left behind, which includes artifacts, architecture, biofacts and cultural landscapes
Material Culture
refers to the relationship between artifacts and social relations
Garbology
the study of (mostly modern) refuse and trash
