Stable isotope dating

28 Jan

More than 100 chips have been designed in this lab, fabricated and successfully tested.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."Near the end you imply that low petrologic type chondrites are the most easily dated.Actually, meteorites that formed by melting, e.g., the various types of achondrites, usually give more precise ages.

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.
