Two aspects of the relation between heavy-element nucleosynthesis and galactic chemical evolution are examined. In the first part, observed heavy-element abundance ratios in the halo and the disk are compared with one-zone models of galactic chemical evolution. These comparisons provide useful insight into the kinds of stellar environments responsible for r- and s-process nucleosynthesis. In the second part, we construct a schematic model for the formation and evolution of the Galaxy based upon the multiple mergers of protogalactic clouds within the expanding and collapsing halo. We analyze the various cosmochronometers within this model and show that the apparent differences between the maximum globular-cluster ages, the white-dwarf cooling age, and the nuclear chronometric ages can be interpreted as indicators of different aspects of the Galaxy formation process.
