The geologic system is a conceptual arrangment of rock formations around the world meshed together into a single, unbroken record of earth's past.[1] It is also known as the geologic column or geologic timescale.

Development of the system was begun in the late 18th century, and the original divisions were Primary, Secondary, Tertiary, and Quaternary. Later, dates were assigned to the divisions according to uniformitarian beliefs about the age of the Earth, and the sections were further divided and subdivided. The system is now divided into eons, eras, periods, and series or epochs.

Creationary geologists use the nomenclature of the system whilst not accepting the uniformitarian dates attached to them.[2][3]

Dr. Jonathan Sarfati explains the relationship between sections of the geologic system and evolutionary belief:

The naming of the eras, in particular, now reflects evolutionary beliefs (Palaeozoic / Mesozoic / Cainozoic), but the period names (Ordovician, Silurian, Cambrian, Cretaceous, etc.) still generally do not. Thus, the naming of the geologic systems is not tied to the assigned ages and assignment of an ore body to a particular geologic system does not necessarily define its absolute age.[4]
