Chemostrat was formed in 1994 to capitalise on research into advanced means of analysing rock samples using a technique called chemostratigraphy.
These new tools include magnetostratigraphy, cycle stratigraphy, chemostratigraphy and sequence stratigraphy.
Thus, we believe that instead of abandoning regional chronostratigraphy or decreasing its resolution, more effort should be put into fording new information and improving the existing criteria for intra- and interregional correlations for which there is a great potential in bio- and chemostratigraphy.
