The separation between the chemical thin and thick disks is defined using [Mg/M]. We use the chemical evolution environment $\\texttt{OMEGA+}$, combined with Levenberg-Marquardt and bootstrapping. We simulate the entire Galactic disk and six galactocentric regions for a more detailed analysis of the formation of the inner, middle, and outer Galaxy.
