Quaternary

The term 'Quaternary' as it applies to the area of coastlines can be defined as ' (1) the youngest geologic period; includes the present time. (2) the latest period of time in the stratigraphic column, 0 - 2 million years, represented by local accumulations of glacial (pleistocene) and post-glacial (holocene) deposits which continue, without change of fauna, from the top of the pliocene (tertiary). the quaternary appears to be an artificial division of time to separate pre-human from post-human sedimentation. as thus defined, the quaternary is increasing in duration as man's ancestry becomes longer'.

The term 'Quaternary' as it applies to the area of reclamation can be defined as ' Refers to the geologic period of the last 2,000,000 years and includes the Pleistocene and Holocene (last 10,000 years) epochs'.
