Note:
In 1856 Alfred Selwyn, who headed the Geological Survey Office in Melbourne from 1852, commenced a systematic program of surveying beginning with Central Victoria and the country around Melbourne which would result in an untitled map series, known informally as the Quarter Sheets. Selwyn engaged a draftsman plus sufficient staff to establish four field parties under geologists Norman Taylor, Christopher Aplin, George Ulrich and Richard Daintree. The survey teams followed a grid pattern through Central Victoria, commencing in Melbourne. Since no reliable topographic maps had been officially produced, Selwyn's geologists had to create their own by using existing cadastral maps as a base which were then overlaid with the geological details. The maps produced had to be large for sufficient ground detail at the scale of 2 inches to the mile but each maps was to be printed in four portions (hence the name Quarter map series) for ease of handling. The maps are annotated, often only in part, with names of the parish or county they partly encompass. Annotations also included geological notes, sometimes on the map itself or in the left or right margins. Most of these maps were published between 1861- 1868 [Angaben von der National Library of Australia]

Historically the first colour printed geological series produced in Australia following the discovery of gold in 1851. As there was no topographic series of Victoria when work commenced in 1856, the geologists spent up to three years surveying the topography and one year determining the geological strata. The first map of quarter sheets of Melbourne were colour printed in 1859 using a conventional hand press but this was very slow & expensive as each sheet had to pass through the press once for each colour. Consequently these maps were not offered for sale until April 1860. Though colour printing was still in its infancy in the 1850s, Thomas Ham, who headed from 1857 the Lithographic Branch of the Government Printing Office in Melbourne, purchased from England the latest steam-powered lithographic press to provide both efficiency and quality. Printing commenced in November 1860 and production increased 4-5 times and costs became more affordable. By the end of 1860 another four maps had been produced. By December 1868 when the Geological Survey was abolished, 59 quarter sheet maps had been produced [Angaben von der National Library of Australia]
