The depth of a sequence plays an important role in studying its linear complexity in game theory, communication theory and cryptography. In this paper, we determine depth spectra of all repeated-root (α+γβ)-constacyclic codes of arbitrary lengths over a finite commutative chain ring R, where α is a non-zero element of the Teichmüller set of R and β is a unit in R. We also illustrate our results with some examples.
