These ions are accelerated in an electric field through collimating slits and subject to a magnetic field which causes the ions to follow a curved path. By adjustment of the strength of the magnetic field and suitable placement of an ion collector, the different isotopes can be measured with precision.There are some things that affect these measurements.These are the surfaces that we can get absolute ages for.For the others, one can only use relative age dating (such as counting craters) in order to estimate the age of the surface and the history of the surface.Thermal processes that may occur during meteorite impact in the lifetime of the specimen can reset some of the atomic clocks, mixing components and releasing important gases such as "You refer to extinct nuclides 14C, 26Al, and 129I.Only the latter two "extinct" nuclides are used in dating.The use of 14C in meteorite dating is solely based on its production by cosmic rays (and for terrestrial samples, with its production in the atmosphere).

When a tree is cut down, these periods are exhibited in a cross section of the trunk in the form of rings.Meteorites are among the oldest objects we know about - formed about 4.5 billion years ago. This article describes the principles and methods used to make that determination.There are well-known methods of finding the ages of some natural objects.Increasingly, the other techniques are used, such that probably no one technique dominates for meteorite dating.Rb-Sr is a good example for explaining the process, however.
