This research reveals Eocene lacustrine deposits in Central Iran, highlighting their distinct geochemistry and environment.

Aliabad deposits were confirmed as Eocene and distinct from the Oligo-Miocene Qom Formation due to their unique composition and age.
Stratigraphic analysis on 46 thin sections revealed a volcaniclastic content averaging around 69% and no Oligo-Miocene fossils.
Geochemical assessments demonstrated the presence of primary volcanic minerals and significant diagenetic alterations affecting the deposits.
Evidence from ichnology and sedimentology indicates a predominantly lacustrine environment with occasional marine conditions and volcanic activity.

Karimi et al. (2025) studied this question.
