The Mudgee 1:100 000 map sheet (8832) occupies the south-east corner of the six 1:100 000 map sheet which comprise the Dubbo 1:250 000 geological map sheet. Some of the original mapping and compilation of the Dubbo geological map sheet by Offenberg et al (1971) - and a minor update by Mason (1973) - the area has been the subject of considerable university thesis work, most notably by students of the University of New South Wales in the 1970s and the University of Wollongong in the 1970s to 1990s. The map sheet area has a range of mineral occurrences and has attracted considerable exploration activity, yielding additional geological data. Mapping and compilation of the Mudgee 1:100 000 map sheet area took place between January and July 1995 and was a joint undertaking by the Geological Survey of New South Wales and the Australian Geological Survey Organisation (AGSO) as part of the National Geoscience Mapping Accord. The project also involved significant collaboration with the staff of the School of Geosciences at the University of Wollongong who have considerable experience in the Mudgee-Cudgegong district. Mapping was greatly asissted by airborne radiometric and magnetic data collected at 400m flight line spacing across the area by AGSO in 1991. A programme of SHRIMP zircon dating of the rocks was undertaken in an effort to establish a better chronological framework for the stratigraphy (Fanning, in prep). The new map (Colquhoun et al 1996b) represents the first thorough synthesis of this comparitively poorly known area of the Lachlan Fold Belt and differs markedly from the Mudgee portion of the original Dubbo geological map sheet. This paper expands on findings which were summarised in Colquhoun et al (1996a) and aims to detail the stratigraphy and structure of the Mudgee 1:100 000 map sheet area and the implications for mineralisation.
