Low visibility phenomena for chronometric dating
catalogue number: a number assigned all items recovered by archaeological research to cross-index them to the catalogue.cation-ratio dating: this method aspires to the direct dating of rock carvings and engravings, and is also potentially applicable to Paleolithic artifacts with a strong patina caused by exposure to desert dust.amino-acid racemization: a method used in the dating of both human and animal bone.Its special significance is that with a small sample (10g) it can be applied to material up to 100,000 years old, i.e. ancillary sample: any non-artifactual materials collected by archaeologists to aid in dating, paleoenvironmental reconstruction, or other interpretations - e.g.
carbon sample: a quantity of organic material, usually charcoal, collected for radiocarbon dating.
cultural resource management (CRM): the safeguarding of the archaeological heritage through the protection of sites and through salvage archaeology (rescue archaeology), generally within the framework of legislation designed to safeguard the past.
culture-historical approach: an approach to archaeological interpretation which uses the procedure of the traditional historian (including emphasis on specific circumstances elaborated with rich detail, and processes of inductive reasoning).
Diatoms are unicellular algae, whose silica cell walls survive after the algae die, and they accumulate in large numbers at the bottom of rivers and lakes.
Their assemblages directly reflect the floristic composition of the water's extinct communities, as well as the water's salinity, alkalinity, and nutrient status. A standard cleaning process in archaeological conservation.
Artifacts are placed in a chemical solution, and by passing a weak current between them and a surrounding metal grill, the corrosive salts move from the cathode (object) to the anode (grill), removing any accumulated deposit and leaving the artifact clean.
