    Abstract

    Packham raises some fundamental points about interpretation of the sub-Upper Devonian unconformity in the Lachlan Fold Belt. He questions the Carboniferous age of the four fold- and cleavage-forming episodes in Lower to lower Middle Devonian units of the Black Range Synclinorium (Hood & Durney 2002) that we had deduced from structural correlation with deformed Upper Devonian rocks and suggests that ‘Some, and perhaps all of them could be Middle Devonian. He evidently regards this method as ‘indirect’ or not ‘definitiv[e]’ and points, instead, to the widespread unconformable relations of Upper Devonian units east of the Gilmore Fault (Figure 1) and to a thermochronological interpretation (Packham1999) of analytical data (Lu et al. 1996b, c) from the Hill End area.
