In the last video, we give a bit of an overview of potassium-argon dating.In this video, I want to go through a concrete example.The work describes some additional considerations for making isochron fits to differentially plotted crater populations with respect to the removal of a binning bias for incrementally/differentially plotted data.
If there were such a pair of isotopes, radiometric dating would be very simple.
In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.
Since there is now only 1/4 of the original amount of Parentium-123, we know that two half-lives of Parentium-123 have elapsed.
The analysis of crater size–frequency distributions and absolute densities forms the basis of current approaches for estimating the absolute and relative ages of planetary surfaces.
Users of the Neukum system of crater dating have conventionally used a cumulative presentation of the data, but because of the recent proliferation of interest in identifying resurfacing ages, it is worth emphasising the utility of the differential presentation of crater data in identifying resurfacing events and, particularly, in distinguishing the signature of short-lived events, such as volcanic flows, from long-acting processes, such as aeolian erosion.
