The Geological Survey of NSW developed a Seamless Geology of UTM Zone 56 during 2014 as part of a project to develop a seamless vector geology dataset of the best available geological mapping data covering the whole of NSW.The overarching aims of the Statewide Seamless Geology Project were to: (i) compile the different original scales, formats and rock unit naming conventions into a consistent, statewide format; (ii) edge-match the geology across existing map sheets; and (iii) interpret the basement geology under cover. The resulting geodatabase comprises a series of layers which include: (i) solid basement geology; (ii) cover rocks (defined as undeformed and unmetamorphosed); (iii) Mesozoic igneous rocks; and (iv) Cenozoic sedimentary and igneous rocks. The project was divided into 3 major stages corresponding to the UTM zones which divide New South Wales. This dataset includes the seamless geology layers from the NSW portion of UTM Zone 56 (ie.east of 150 degrees longitude to the coast).

Identifies Mineral Claims Districts in the State of NSW as defined by Part 9, Division 1, Section 173 of the Mining Act 1992 No. 29. There are two current Mineral Claims Districts: Lightning Ridge Mineral Claims District, and White Cliffs Mineral Claims District.

Gazetted Reserves which exclude mining and/or exploration operations. Specifically for use in the Lightning Ridge and White Cliffs areas.

Pseudocolour image of the ratio between uranium and thorium within the upper 20 centimetres of the ground. Cooler colours indicate lower abundances of uranium relative to thorium and warmer colours represent the opposite. Variations in U2/Th ratio are caused varied mineral compositions in host rocks and soils. This statewide image was generated by merging many individual airborne radiometric surveys.

Identifies Opal Prospecting Blocks in the State of NSW as defined by Part 10, Division 1, Section 224 of the Mining Act 1992 No. 29.

Magnetic and radiometric data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.

EM-IP-MT survey data has been reported to the NSW government and released under the requirements of the NSW Mining Act 1992. Contained within this vector file is the location of surveys and acquisition parameters.
