Lake Turkana has a geologic history that favored the preservation of fossils. Scientists suggest that the lake as it appears today has only been around for the past , years. The current environment around Lake Turkana is very dry. Over the course of time, though, the area has seen many changes. Over time the sediment solidified into rock.

Related to radiometric dating: Carbon 14 dating. A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it and the half-life of that isotope. All rights reserved. Also called: radioactive dating. Copyright , , by Random House, Inc. A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it. The amount of the isotope in the object is compared to the amount of the isotope's decay products.
Dating Fossils in the Rocks
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
Define Radiometric Dating In Archaeology. Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using Definition of radiometric dating in the Definitions dictionary.
