Geology
Flo parish is the namesake for the Floian stage, which is the second stage of the Lower Ordovician.[1] The base of the Floian is defined at the Diabasbrottet quarry type section (GSSP) 5 km to the northwest of Flo. The base is defined in the quarry as the lowest stratigraphic occurrence of the graptolite species Tetragraptus approximatus.[2]
