Chronometric dating definition

Chronometric Dating for the Archaeologist isn't bedtime reading, nor is it for the faint-of-heart, but at the same time one does not have to have a background in materials science or organic or inorganic chemistry to understand the basic premise of the work.The editors' goal is to present a factual, current, and well-documented evaluation of a dozen of the major techniques that are used by scientists to determine chronology from archaeological artifacts or contexts.Excavation: Archeologists excavate buried cultural remains to both gather information about past human behavior and to preserve and protect cultural resources from destruction, either from human or natural processes. Discussed below are the three major types of dating used in archeology – relative dating, chronometric dating, and absolute dating – and some of the more popular methods employed in each general category.Archeological excavations, or “digs,” are conducted using very specific methods and rigorous vertical and horizontal spatial controls. Relative dating in archeology determines the age of cultural material in relation to other cultural material, but does not produce precise dates.The ages assigned to these fossils have been obtained through radiometric dating of volcanic rocks interbedded with the fossiliferous sediments.Such numerical calibrations are crucial to understanding rates and timing of evolutionary change.Among the most useful chronometric dating techniques are radiocarbon dating, potassium argon dating, and thermoluminescence dating.Dendrochronology, the relationship of dated ancient trees with live trees has no CATEGORY: technique DEFINITION: The use of various methods, often multiple methods, to demonstrate the equivalency of stratigraphic units.

Lastly, there is a conclusion that incorporates a general discussion about this volume and its relationship to similar works and the current status of chronometric or "time placement" dating.

However, experiments with seriational methods suggest that greater resolution may be obtained through the quantitative analysis of attribute frequencies.

The chronological resolution obtained by these relative dating methods is at least equal to the resolution possible with chronometric methods.

In the Southwest, and particularly in CRM, there are several defined types of survey: Remote Sensing: Remote sensing in archeology employs a wide variety of aerial and satellite imaging, as well as radar, sonar and lidar, to build landscape images useful for recognizing archeological materials not visible to ground crews.

Many remote sensing techniques rely on portions of the electromagnetic spectrum, such as infrared, that humans are typically unable to see.
