Elongate sand bodies may be classified as depositional dip sands (alluvial, channel, etc.) or depositional strike sands (bar, barrier, etc.). Bar and barrier sand bodies generally exhibit several characteristic properties.

These properties define the sand body and permit its identification. Depositional strike
