ResumoU‐Pb zircon radiometric dating and petrographic thin‐section analysis were used for provenance identification of Ferrería and Marrón Inciso pottery styles from La Morena archaeological site in northwestern Colombia. U‐Pb dating was applied to zircons recovered from pottery and rock samples from nearby geological units. The results suggest at least three distinct sources: the metamorphic rock unit on which the archaeological site is located, a granodiorite unit that outcrops further away from the site, and a mafic rock that cannot be attributed with certainty. U‐Pb in zircons proved to be effective as a provenance method, where ages of the possible source rocks are well constrained, and can be applied to areas where traditional sourcing methods may be problematic.
