  In this contribution talk we summarize the results of our ongoing project of
detailed analysis of the chemical content (chemical tagging) as a promising
powerful method to provide clear constraints on the membership of FGK kinematic
candidates to stellar kinematic groups of different ages that can be used as an
alternative or complementary to the methods that use kinematics, photometry or
age indicators. This membership information is very important to better
understand the star formation history in the solar neighborhood discerning
between field-like stars (associated with dynamical resonances (bar) or spiral
structure) and real physical structures of coeval stars with a common origin
(debris of star-forming aggregates in the disk). We have already applied the
chemical tagging method to constrain the membership of FGK candidate stars to
the Hyades supercluster and the Ursa Major moving group and in this
contribution we present the preliminary results of our study of the Castor
moving group.
