Lineage

The NSW Seamless Geology Project team has compiled the best available geological data for the state into an internally consistent geodatabase. As part of the compilation process, contributing datasets were organised into a series of layers, or time slices, that represent the major lithotectonic subdivisions of the state’s geology. The data was then stitched/smoothed along existing map and dataset boundaries to create a seamless dynamic model of the geology of NSW. Important datasets and projects that contributed to the NSW Statewide Seamless Geology dataset are detailed below.

• Between the 1950’s to 1970’s, first and second edition 1:250,000 scale geological maps were published by the GSNSW over a large portion of the state. These include the Angledool (Offenberg 1966), Barnato (Rose 1965), Bega (Packham 1967), Bourke (Brunker 1971), Broken Hill (Rose 1970), Canberra (Best, D’Addario, Walpole & Rose 1964), Cobar (Brunker 1969), Cargelligo (Griffin 1960; Bryan, Connolly & Pogson 1967), Cobar (Brunker 1969), Cobham Lake (Brunker & O’Connell 1967), Cootamundra (Rose 1967), Dorrigo-Coffs Harbour (Leith, Neilson & Hobson 1971), Dubbo (Offenberg, Rose & Packham 1971), Enngonia (Johnson & Menzies 1965), Forbes (Brunker 1972), Gilgandra (Offenberg 1968), Goondiwindi (Mond et al. 1972), Goulburn (Brunker & Offenberg 1970), Grafton (Brunker & Chesnut 1976), Hastings (Brunker, Offenberg & Cameron 1970), Inverell (Chesnut & Cameron 1971), Ivanhoe (Bryan 1968), Jerilderie (Whiting et al. 1957; Tuckwell 1976), Louth (Loudon, Menzies & Wallis 1965), Maclean (Rose 1970), Manara (Bryan, 1967), Manilla (Chesnut, Flood & McKelvey 1973), Menindee (Rose 1969), Milparinka (Rose, O’Connell & Menzies 1967), Moree (Staude 1968), Narrabri (Wallis 1971), Narrandera (Wynn 1962; 1977), Narromine (Brunker 1967), Newcastle (Rose, Jones & Kennedy 1966), Nymagee (Brunker 1968), Singleton (Rasmus, Rose & Rose 1969), St George (Senior & Senior 1971), Sydney (Joplin et al. 1956; Rose 1961), Tallangatta (Adamson et al. 1966), Tweed Heads (Brunker et al. 1972), Ulladulla (Rose 1966), Ursino (Brunker & O’Connell 1966), Wagga Wagga (Adamson & Loudon 1966), Warwick (Olgers et al. 1972), White Cliffs (Rose, Louden & O’Connell 1964), Wilcannia (Frenda 1965), Wollongong (Joplin et al. 1952; Rose 1966) and Yantabulla (Wallis & McEwen 1962) 1:250,000 maps. It should be noted that due to the absence of accurate base maps in parts of NSW at the time of compilation of these early 1:250,000 maps, many of these maps were compiled on inaccurate base maps. As a result, errors of up to 1.2 km in location can occur. Attempts were made to correct this problem during the NSW Statewide Seamless Geology Project. All features were rubbersheeted to a re-georeferenced map (based on SPOT 5 satellite imagery) during December 2014 to March 2015 using thousands of control points. However, some inaccuracy of features may remain in these older 1:250,000 geological maps.

• From the 1990’s onwards 1:250,000, geological map sheets were completed on much better-quality base maps and should be considered more accurate than the 1950's-70's maps. These include the Ana Branch (Ray 1997), Bega-Mallacoota (Lewis & Glen 1995), Booligal (CAMERON 1997), and Cootamundra (Warren, Gilligan & Raphael 1996), Nyngan (Watkins 1996) and Walgett (Meakin et al 1996). These maps were completed in the era just prior to the acquisition of modern regional geophysical data.

• During the 1980's and early 90's many of 1:250 000 maps in the New England area were remapped as part of the Survey's Metallogenic Mapping Program.

• 1:100,000 scale geological mapping was undertaken during the 1970’s 1980’s and early 1990’s, resulting in greatly increased level of detail over sheets like: Taralga (Scheibner 1969), Yass (Cramsie et al. 1975), Brindabella (Owen & Wyborn 1979), Tantangara (Owen & Wyborn 1979), Canberra (Abell 1992), Michelago (Richardson & Barron 1977), Araluen (Wyborn & Owen 1982), Sydney (Herbert 1983), Braidwood (Felton 1975), Wollongong-Port Hacking (Stroud, Sherwin, Roy & Baker 1985), Tumut (Basden 1990), Penrith (Clarke & Jones 1991), Camberwell (Roberts, Engel & Chapman 1991), Dungog (Roberts, Engel, Lennox & Chapman 1991) and Bulahdelah (Roberts, Engel, Roy & Chapman 1991). Detailed mapping over the Cooma-Michelago area (Henderson 1987) and Bombala 1:100,000 sheet (Brown, McQueen, Lewis, Taylor, Veitch, Edgecombe & Roach 2004) occurred in the latter end of this era. The Cobar-Nymagee 1:100,000 mapping project took place from late 1970’s until the late 1980’s, resulting in a substantial upgrade in the geological knowledge of the region and 11 new 1:100,000 geological sheets over the Cobar and Nymagee 1:250,000 map sheet areas: Bobadah (Pogson 1991); Booroondara (Glen et al. 1985); Canbelego; Cobar (Glen, 1994); Gindoono (Macrae & Pogson, 1985); Kilparney (Trigg, 1985); Lachlan Downs (Macrae 1989); Nymagee (Macrae 1988); The Meadows (Watkins & Henley, 1985); Wrightville (Glen et al. 1985). Synthesis metallogenic sheets were compiled over the Bourke (Byrnes et al. 1993), Cobar (Gilligan et al. 1994) and Nymagee (Suppel & Pogson 1993) 1:250,000 sheets at the end of 1:100,000 series mapping.

• During the early 1990’s, regional geophysics became available to geological mapping projects for the first time. This resulted (from 1994 to 2001) in many 2nd generation geological maps being produced at 1:100,000 scale over the Bathurst, Dubbo, and Forbes 1:250,000 map sheet areas under the National Geoscience Mapping Accord (Geological Survey of NSW and AGSO – now Geoscience Australia). This detailed mapping over areas with detailed geophysics has continued with the Angledool 1:250,000 sheet 2nd Edition (released 2011), 6 x 1:100,000 map sheets of the Goulburn 1:250,000 (released 2008), the Captains Flat Special 1:50,000 and the Braidwood 2nd Edition 1:100,000 sheet (both released 2017). Mapping also continued in Central NSW, extending the work of the Cobar-Nymagee project of the 1980’s. This saw of the completion of the Cargelligo 1:250,000 Sheet 3rd edition (Meakin et al. 2006) and its constituent 1:100,000 sheets. More recently, 1:100,000 sheets geological sheets have been completed over Byrock (Burton et al 2013a), Coolabah (Gilmore et al 2017a) , Mt Oxley (Gilmore et al. 2017b), and Sussex (Burton et al 2013b). In addition, a major project of geological mapping is currently underway in the East Riverina area of southern NSW which is remapping parts of the Narrandera, Cootamundra, and Wagga 1:250,000 sheets at 1:100,000 scale. Provisional versions of the new East Riverina geological dataset have been included in version 1 of the NSW Seamless Geology dataset.

• During the late 1990's and early 2000's, several large regional geological compilations were carried out as part of forestry and bioregion studies in the New England area and also in the southern parts of Zone 56. These included: the Lower Northeast Regional Forestry Agreement (1999), the Upper Northeast Regional Forestry Agreement (2000), the Southern Regional Forestry Assessment (2000), the Nandewar Western Regional Assessment (2003), the Brigalow Belt South Bioregion Assessment (2003), and the Comprehensive Coastal Assessment Quaternary Geology (2004). Other important compilations undertaken by the GSNSW in this period were the East Lachlan Orogen datasets (2004 and 2007) and the Coalfield Regional Geology series [Western Coalfield South (1992), Hunter Coalfield (1994), Newcastle Coalfield (1995), Western Coalfield North (1998), and Southern Coalfield (1999)]. Collectively, these studies resulted in a rapid upgrade of the geology datasets covering large areas of Zone 56. In particular, the various compilations in the New England Orogen area substantially improved the geological coverage of the region, with the existing GSNSW 1:250,000 and 1:100,000 Geology and 1:250,000 Metallogenic Maps being combined with numerous thesis maps and other previously unpublished mapping (in particular, compilations of Carboniferous geology by John Roberts). These compilations were brought together and merged during 2004-05 by Ken McDonald and Mark Dawson. Collectively, these regional compilation datasets form the basis of much of the Zone 56 Seamless Geology dataset apart from in the greater Sydney area and in several areas covered by more recent geological mapping, namely: Woodburn 1:100,000 Geological Sheet (2003), Bare Point 1:100,000 Geological Sheet (2004), Warwick-Tweed Heads 1:250 000 Metallogenic Map (2013 - provisional), Manilla 1:100,000 Geological Sheet (2013), Moss Vale 1:100,000 Geological Sheet (2013 - provisional), and Gosford-Lake Macquarie 1:100,000 Geological Sheet (2013 - provisional). As an extension of these projects, interpretation of the Quaternary systems was also continued by Mark Dawson up until the mid-2000’s over the Moree, St George, and Wagga 1:250,000 sheets.

• A major synthesis project over Zone 55 East was the East Lachlan Orogen dataset, produced in two versions in 2003 (v1) and 2007 (v2). This dataset produced a best available merge of the geological mapping datasets which existed at that time and provided a solid geology (Pre-Permian) interpretation. The Lachlan Orogen layer of the Seamless Geology Zone 55 East (v1) dataset has relied heavily on version 2 of East Lachlan Orogen dataset (Glen, Dawson & Colquhoun 2007) which has been updated with mapping datasets completed since that time (ie. 6 x1:100,000 sheets from Goulburn 250K, Bombala 1:100,000 and the Cooma-Michelago 100K Special, + some thesis mapping and diagrams from the Bathurst Explanatory Notes) . A full lineage statement from the East Lachlan Orogen v2 dataset is included separately below (following the list of data sources) as there were extensive changes and edits made to the original datasets during the East Lachlan Orogen synthesis project which have carried through to the current Zone 55 East Seamless Geology dataset.

• During 2009-2013, the GSNSW Statewide Geology Geodatabase was extensively remodelled and upgraded. Over this period, all the existing digital vector geology datasets held by the GSNSW were imported into the new geodatabase schema, and assigned a standard set of attributes, projections and data structure. In addition, a program to back capture data from older maps and compilations was also undertaken, resulting in over 70,000 structural data points and 18 entire geology maps being captured.

• The Seamless Geology Project commenced in 2013 when merges of the best available datasets began to be assembled in the Statewide Geology Geodatabase (v.2) format. The source datasets for these merges are shown in the feature class “Seamless_V1_Source_Datasets” in this geodatabase. This merged dataset was divided into stratotectonic layers which were then edited by a small team of geologists, resolving edge-match issues and nomenclature problems between the geology of adjacent map sheets, and interpreting various layers under the cover of overlying layers. This produced a series of seamless geology layers which showed, for the first time, the actual distribution of rock units and structures, both in outcrop and under cover. These datasets were released progressively across the state as this work was completed, with three packages having been previously released; a Zone 56 dataset (Colquhoun, Phillips, Hughes, Deyssing, Fitzherbert & Troedson 2015), a Zone 54 dataset (Colquhoun, Phillips, Ballard, Hughes & Deyssing 2016) and a Zone 55 East dataset (Colquhoun, Deyssing, Ballard, Hughes & Troedson 2017). Zone 55 West was completed in mid-2018 but was not released as a separate dataset. Instead, the Zone 55 West data was merged with the previously released Seamless Geology datasets from the various zones and merged and harmonised to produce the first statewide Seamless Geology of NSW (version 1) in October 2018.

• This complete release of the Statewide Geology Geodatabase replaces the earlier individual datasets. As well as providing the first coverage of Zone 55 West, it also incorporates updated mapping from the Warrumbungle region (Troedson & Bull 2018).

• The Great Australian Basin had a review in 2018 and the boundary has been updated to reflect new data. The update was required as there were several different versions of the Boundary available. Details can be found in HUGHES et al. (2018).

• A complete list of the data sources which were used in the compilation of the Great Australian Basin layer of the Statewide Seamless Geology dataset appears below. More details on which datasets were used in specific areas can be obtained by interrogating the fields "Src_Data", "MapName" and "MapNumber" and by referring to the accompanying feature class “Seamless_V1_Source_Datasets” in this geodatabase.
