The lithology primarily consists of fluvially deposited siliciclastics derived from volcanic material.

The strata of the Eumeralla Formation are folded as a result of northwest–southeast crustal compression during the Neogene, which also reactivated some Cretaceous aged normal faults.

[2] It is one of three major fossiliferous deposits in Victoria dating to the Early Cretaceous, including the older Wonthaggi Formation and the Koonwarra fossil bed (which some authors have considered part of the Eumeralla Formation).
