Abstract

The recovery of a small Early to Middle Llandovery (Early Silurian) conodont fauna from core samples in two wells (WMC Acacia 1 and WMC Boab 1) is the first documentation of Silurian rocks in the Canning Basin. The recovery of Ozarkodina hassi from both wells allows correlation of this fauna with the Rhuddanian to Aeronian Stages (Early to Middle Llandovery), which equates with the acuminatus Zone to sedgwickii Zone graptolite faunas. The samples are from a stratigraphic unit defined as the Lower Carbonate Member of the Worral Formation, but lithologic characteristics and age constraints indicate that the lower portion of this carbonate is part of the underlying Sahara Formation, the uppermost unit of the Carribuddy Group. The overlying Worral Formation (restricted) is of late Early to Middle Devonian (Emsian-Eifelian) age. This relationship has implications for the resource potential of the Canning Basin.
