Relative dating archaeology
The methods have varying applications, accuracy, range, and cost.
Many new techniques are being developed and tested.
Microbial trophic group composition significantly correlated to soil p H, but not to prior precipitation reconstructions.
Further refinement is required before the paleoclimatic reconstruction method can be implemented with confidence.
Additionally, microbial density decreased with age, suggesting a temporal signature within the sample column and that density could potentially be used as a relative dating technique.
To test the paleoclimatic reconstruction method, trophic group data were tested for serial correlation and compared to soil and phytolith analyses formerly completed at the site.The date on a coin is an absolute date, as are AD 1492 or 501 SYNONYMS OR RELATED TERMS: relative dates; relative dating techniques CATEGORY: technique; chronology DEFINITION: Dating methods where phases or objects can be put into a sequence relative to each other, but which are not tied to calendrically measured time.
