Abstract
Internally laminated conical mounds characterise a regionally extensive chert unit near the top of the 3,400-Myr old Warrawoona Group in the Pilbara Block of Western Australia. The chert formed by silicification of a carbonate–evaporite sequence deposited in shallow subtidal to intertidal environments. The morphology and internal organisation of the mounds described here suggests that they are conical stromatolites similar but not identical to members of the common Proterozoic group Conophyton Maslov.
