Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
World Developments in 2006, (From AAPG Explorer, January 2007), #10120 (2007). Early Permian Siliciclastic System of North-Gondwanaland: A Comparison between Nilawahan Group of North Pakistan and Haushi Group of Oman, Iftikhar Ahmed Abbasi, Muhammad Haneef, and Mohammad Asif Khan, #30227 (2012). (For brevity's sake, hereafter I will refer to the parent isotope as ).In addition, it requires that these measurements be taken from several different objects which all formed at the same time from a common pool of materials.The only problem is that we only know the number of daughter atoms now present, and some of those may have been present prior to the start of our clock. The reason for this is that Rb has become distributed unequally through the Earth over time.We can see how do deal with this if we take a particular case. For example the amount of Rb in mantle rocks is generally low, i.e. The mantle thus has a low If these two independent dates are the same, we say they are concordant.
