Because the isotope composition of this sample plotted on the meteorite isochron, it suggested that earth had the same age and origin as meteorites, therefore solving the age of the Earth and giving rise to the name'geochron '.

Algebraically eliminate the immaterial constant B from these two equations to deduce that all initial conditions y _ 0 + y'_ 0 = 1 + A have the same A, hence the same long term evolution, and hence form an isochron.

The change in slope from initial conditions assuming an initial isochron slope of zero ( a horizontal isochron ) at the point of intersection ( intercept ) of the isochron with the y-axis to the current computed slope gives the age of the rock.

Find which isochron the initial values ( x _ 0, y _ 0 ) lie on : that isochron is characterised by some X _ 0; the initial condition that gives the correct forecast from the model for all time is then X ( 0 ) = X _ 0.

Many believers in young Earth creationism a position held by the majority of proponents of flood geology accept biblical " chronogenealogies " ( such as the Ussher chronology, which in turn is based on the isochron analysis, both of which are central to mainstream geological theories of the age of the Earth.

A number of additional modern homages to " X-COM " have been produced, including the open source, cross-platform " UFO : Alien Invasion "; as well as " Isochron " ( TBD ) and " Xenonauts " ( 2014 ) by JSeuss Software and Goldhawk Interactive, respectively.

The ratios D + \ Delta { P } _ t \ over D _ i ( relative concentration of daughter and non-radiogenic isotopes ) and { P-\ Delta { P } _ t \ over D _ i } ( relative concentration of parent and non-radiogenic isotope ) are measured by mass spectrometry and plotted against each other in a three-isotope plot known as an " isochron plot ".
