The outer rings of trees are those that are nearest the time of death of the tree and should be preferentially selected for dating.

Fortunately, atmospheric argon contamination can be assessed by measurement of the different isotopes of argon present.Similarly, radiocarbon ages on growth-position fossils associated with a surface directly below lake sediments deposited in a landslide-dammed lake can be reliably linked to the age of the event.Unfortunately, such occurrences are extremely rare. All fossil plant material and bones entombed in landslide deposits are “detrital,” that is, they have been transported to their depositional positions.Atmospheric argon occurs as three isotopes, Ar dating is the (unknown) degree to which argon has been lost from the system since the time of the geologic event to be dated.

This may result from a number of factors, including diffusion, recrystallization, solution, and chemical reactions as the rock weathers (Ar dating technique is that potassium and argon measurements have to be made on different parts of the same sample; if the sample is not completely homogeneous, an erroneous age may be assigned.Similarly, certain rocks may have incorporated older “argon-rich” material during formation.
