Name proposed by Walpole (1949) and published by Joplin et al. (1953) for the basal rhyolitic unit of the Black Range Series. Browne (1959) used instead the name Narrangullen Rhyolite, and further complicated matters by naming the upper unit of the Black Range Series the Mountain Creek Tuff. Although this was followed by Packham et al. (1969) and Pedder et al. (1970), most workers have returned to the nomenclature of Joplin et al. (1953); eg in Brunker and Offenberg (1970); Offenberg (1974), it overlay their Derringullen Formation. Type section and "good outcrops" are described. From 500 up to 4,000m thick, thinning to the S. Is correlated with the sequence in the Yass Syncline consisting of Sharpeningstone Conglomerate, Pilleuil Andesite and Waynes Knob Rhyolite, as well as Warrangong Volcanics.

13443|Mundoonen Sandstone|71700|3|Fully described|vi, viii, p7, p9, p48-p50, |Llandovery|Early Bolindian|Named for the Mundoonen Range between Yass and Gunning in Goulburn250. The initial usage of this unit (Sherrard 1939) included parts of what is now mapped as Bendoc and Adaminaby Group. This unit now incorporates rocks previously regarded as Birkenburn Beds and De Drack by Felton and Huleatt (1975, 1977). This unit contains two unnamed packages; a sandstone-rich and siltstone-rich package. A type area is implied in the Mundoonen Range and a representative section south of the Mundoonen Trigonometrical Station was nominated in Thomas and Pogson 2012. This unit is estimated to be almost 1300m thick near the Mundoonen Trigonometrical Station. Lithology of the informal sub-units is described. Distribution, structure, geomorphic expression, outcrop, metamorphism, geophysical characteristics, depositional environment and distinguishing features are discussed. Faulted against the Abercrombie Formation. Equivalent to the Poidevins Sandstone, Dignams Siltstone, New Country Sandstone and the Willandra Sandstone. The age of this formation is poorly constrained but may extend into the Silurian. This unit is interpreted as the resumption of terrigenous sedimentation related to glacio-eustatic lowering of sea level in the early to mid Bolindian. Overlain by the Bango Limestone Member of the Hawkins Volcanics. Intruded by the Bundong Granite. See also p52, p64, p83, CD.||Margules Group||Conformably overlies the Warbisco Shale. Unconformably overlain by the Woodlawn Volcanics of the Mount Fairy Group.|Medium- to very thick-bedded, fine- to coarse-grained quartzose sandstone, and interbedded grey, buff and khaki siltstone which is ferruginised in places. The sandstone is rounded to sub-rounded and generally moderately-sorted.|

A composite type section is proposed from GR 731650 6117420 to GR 732713 6116984.The Woodlawn Volcanics is depicted as a combination of undifferentiated Mount Fairy Group and unnamed granite on the 1st edition Canberra 1:250 000 geological sheet (Joplin et al. 1953), and partly as Ellenden Granite and partly as"Mount Fairy Beds" on the Canberra 1:250 000 2nd edition geological sheet (Best et al. 1964). Rhyolites within the De Drack Formation were previously labelled Woodlawn Volcanics on Braidwood100. Other rocks previously assigned as Woodlawn Volcanics have been included in the Quialigo Volcanics. Contains two unnamed constituents. Distribution, geomorphic expression, outcrop, depositional environment, metamorphism, geophysical characteristics, fossils, geochemistry, structure, distinguishing features and economic geology are discussed. Lithology at various areas, including the type section is provided. Additional SHRIMP ages of 423.3 +/- 2.6 Ma are derived from Bodorkos et al, 2010 and 419.2 +/- 3.2 Ma from Bodorkos and Simpson, 2008. Unconformably overlies the Warbisco Shale and the Abercrombie Formation. This unit correlates with Kohinoor Volcanics, Kangaloolah Volcanics and the Bells Creek Volcanics.The lower volcaniclastic wedge is up to 900m thick and the upper volcanic pile is up to 820m thick. Hosts the Woodlawn Zn-Pb-Cu-Ag (Au) mine.
