It is possible to tell the number of years ago a particular rock or archeological site had been formed. However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order. These rates of decay are known, so if you can measure the proportion of parent and daughter isotopes in rocks austin hookup bars, you can calculate when the rocks were formed.
