There are some problems for dating of geological events in isotopic chronology like sample choosing, dating methods and man factors.

K-feldspar, a ubiquitous mineral in igneous and metamorphic rocks, has long been used in K-Ar dating.

In this paper,we review some major dating methods,such as paleomagnetic?40Ar39Ar?PbPb isotope?RbSr?SmNd?fission track methods and so on,and illuminate the role of precision dating in investigating the genesis of MVT deposit.

In this paper,we review some major dating methods that are after used,such as paleomagnetic 40Ar- 39Ar, U-Pb, Rb-Sr, Sm-Nd, fission track methods,and illu.

In recent years, the quaternary geochronology and the dating methods are very fast developed with the advanced techniques which include mass spectrometric analysis, thermal ionization mass spectrometrer (TIMS), accelerator mass spectrometer(AMS) and the chemical separation of samples.
