Bramerton Borehole (740 ft), Bramerton [Norwich Crag] (Pleistocene of the United Kingdom)

Where: England, United Kingdom (52.6° N, 1.4° E: paleocoordinates 52.6° N, 1.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Norwich Crag Formation (Crag Group), Early/Lower Pleistocene (2.6 - 0.8 Ma)

• STRATIGRAPHIC RELATIONS: From the Norwich Crag of the Crag Series, which locally unconformably overlies chalk (Cretaceous or Paleogene?). AGE: Early Pleistocene, Icenian. STRATIGRAPHIC POSITION: From zone BM1, 740 ft below surface

Environment/lithology: coastal; unlithified, shelly/skeletal, argillaceous, calcareous sandstone

• SPECIFIC LITHOLOGY: Sands with occasional clay streaks and a few shell fragments throughout. LITHIFICATION: Unlithified, on the basis of facies description of sample preparation.

Size classes: macrofossils, mesofossils
