Question

Difference between archaeological and geological time scale

Answer 1

Essentially there should be no differences in how sediments, soils, or older paleontological deposits are recorded. Especially in the case of recent deposits, geomorphology and soil sciences are crucial to appropriate characterizations of sediment or soil formation and development of inferences about archaeological site formation. Unfortunately, a number of conventions used in much archaeological research (at least in the US, and especially in CRM archaeology ) are minimally informed by standard soil development knowledge and process geomorphology. I would very strongly urge all archaeologists who are interested in site formation, or who want to be able to ask informed questions of their geoarchaeology colleagues beyond "how old are these deposits" and "are they intact" to get some training in both soil science and geomorphology, as well as geoarcharchaeology. Some geomorphologists occasionally employ relative archaeological dating to deposits, assuming that artifact chronologies may be reliable (and sometimes they are), but otherwise the ways they record soil profiles, sediments, or landscape development are crucial to more informed and useful archaeological site formation studies.

Geological time scale-

1) The geologic time scale (GTS) is a system of chronological dating that relates geological strata (stratigraphy) to time, and is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth's history.

2) The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy.

Archaeological time scale-

1) Archaeological timescale, also called archaeological chronology, chronology that describes a period of human or protohuman prehistory. Some archaeological timescales are based on relative dating techniques, such as stratigraphy, which illuminate a sequence of change. Others are based on chronometric (absolute) methods such as carbon-14 dating and dendrochronology that derive a specific date from a specific item or sample (as of carbon).

2) Most also include geographic information, as change generally varies over space as well as time. The scales of time and space considered vary depending upon the purpose of the archaeological chronology: a timescale describing the development of a locale from prehistoric campsite to medieval village to modern town might be measured in centuries and spatially restricted to a few acres or hectares, while one describing human evolution would be measured in millennia and would consider space at the level of the ecosystem or continent.
