Description: Shale/sandstone laminite.
Comments: Within the Narrabeen Group. Appears to have been upgraded to Burralow Subgroup of the Narrabeen Group? - but requires confirmation. Continued usage of Formation suggests change of rank not widely accepted, or was a misspelling. June 2012 GSNSW state list places this unit in Gosford Subgroup, Narrabeen Group.
