It is the
branch of geology which deals with the study of finding the age of a rock body
and the events associated with it. The term of Geochronology was first
introduced in 1983 by H.S Williams, an American Geologist and described it as a
discipline which is related to the study of time and the related geological
events happening in earth history. It helps in finding the questions such as
when did a geological event occurred? when did the tectonic plates collided?
what is the rate of subduction or uplifting of a plate? Are the rocks of one
area same in age as the rocks in the other area? Geochronology is the heart of geology. It provide a base for the interpretation of the other fields of geology in respect to the history of earth.
