Metallicity profiles store information about the history of galaxy formation. These chemical patterns arise from the complex interplays between a variety of physical processes such as star formation, gas inflows/outflows, SN/AGN feedback, galaxy mergers and galaxy interactions. Using a set of simulations of the Chemo-dynamIc propErties of gaLaxies and the cOsmic web project, CIELO, we followed the assembly process of two central galaxies and were able to identify some of the most important events that participate in their formation. We studied the properties of the gas involved and relate these events to the characteristics of the gas-phase metallicity profiles, identifying a great variety of gradients and breaks during the evolution of our case studies. In this talk, we will discuss how different physical processes affect the inner and outer regions of the galaxy, emphasizing that a single process can have different stages leading to different metallicity distributions. We will also provide some characteristic timescales for the survival and recovery of disturbed metallicity profiles. This work contributes to the understanding of the observed variety of metallicity distributions in star-forming galaxies.
