A good example of an application of the Re-Os isochron method is a study on the dating of a gold deposit in the Witwatersrand mining camp, South Africa.

B ) In the Dharwar Craton studies done on the trondhjemites of Holenarsipur, major crust forming event are attributed through the Rb & ndash; Sr whole rock isochron ages.
23.
Coyne believes that both sides of such debates between evolutionists and young earth creationists could benefit from a better understanding of the fossil record and for modern tools such as Isochron dating.
24.
However, use of a single decay scheme ( usually 238 U to 206 Pb ) leads to the U Pb isochron dating method, analogous to the rubidium-strontium dating method.
25.
Since the ratio of the daughter and non-radiogenic isotopes is proportional to the ratio of the parent and non-radiogenic isotopes, the slope of the isochron gets steeper with time.
26.
In the mathematical theory of dynamical systems, an "'isochron "'is a set of initial conditions for the system that all lead to the same long-term behaviour.
27.
The Kane Fracture Zone offsets the MAR left-laterally by at 24�N . Its fossil trace on the western side of the MAR stretches some westward to the 80 Ma isochron ( anomaly 34 ).
28.
All forms of isochron dating assume that the source of the rock or rocks contained unknown amounts of both radiogenic and non-radiogenic isotopes of the daughter element, along with some amount of the parent nuclide.
29.
The slope of the isochron, \ Delta { P } _ t \ over P-\ Delta { P } _ t, represents the ratio of daughter to parent as used in standard radiometric dating.
30.
Whole rock isochron dating uses the same ideas but instead of different minerals obtained from one rock uses different types of rocks that are derived from a common reservoir; e . g . the same precursor melt.
