Relative chronometric dating techniques
Others, such as radar-based techniques, can penetrate cloud cover, forest canopies, and the ground to reveal materials and landscapes otherwise invisible from the air. (before common era/common era), corresponds to the standard calendrical system, whereas B.
Several important types of remote sensing used in archeology are discussed below. P., when used in the context of reporting radiocarbon assays, measures dates in radiocarbon years from the ‘present’ of 1950.
Since the nests are often rebuilt and reused over long periods of time, it is possible to reconstruct local vegetation regimes datable through radiocarbon dating techniques.
In the Southwest, some environmental reconstructions based on packrat midden analysis extend back into the Pleistocene.
These methods are employed to first locate and identify sites, features, and artifacts, and then to reconstruct the temporal associations, cultural histories, functions, and meanings of the same archeological material. In fact the question is so general that we may be speaking of any form of dating. Relative dating allows you to say that Julius Caesar was born before Napoleon.
