Study Notes

Lithostratigraphy

A lithostratigraphic unit is primarily based on rock type and its physical characteristics.
Formations are the fundamental lithostratigraphic units, representing distinct rock bodies with unique lithological features.
Members are subdivisions within formations, characterized by a specific rock type or internal structure.
Supergroups are the largest lithostratigraphic units, comprising multiple formations and groups that share similar lithological and stratigraphic characteristics.

Chronostratigraphy

Chronostratigraphic units are based on age, reflecting specific intervals of geological time.
The primary basis for defining chronostratigraphic units is fossil evidence and radiometric dating, which help establish the relative and absolute age of rock layers.
Lithostratigraphic units are based on rock type and physical characteristics, while chronostratigraphic units focus on the age of rocks.
