I applied my mind to study and to explore by wisdom all that is done under the heavens. What a heavy burden God has laid on mankind!
Ecclesiastes 1:13 NIV
- Geological formation (Wikipedia)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers.
