dc.descriptionThe star formation history of a galaxy, explicitely here our Milky Way Galaxy, where the most detailed information is attainable, is the convolution of two functions. One function describes the rate of formation of the stars which are today in the Galaxy. The second describes the assembly of those stars into the present Galactic potential well. There is direct evidence that this assembly continues today, with both stars and gas being assembled into, or at least rearranged in, the Galactic potential. But is this recent accretion significant? Was the last significant accretion the formation of the thick disk, some 10Gyr ago?. Recent spectroscopic studies support this unexpected result, while dynamical studies find increasing numbers of specific examples of smaller scale more recent accretion. We present early results for one specific such survey, the Anglo Australian Old Stellar populations Survey, to illustrate current studies.
