Tachylite in Victorian archaeological sites
Tachylite is an unusual and relatively rare stone used in making flaked stone tools, and which is found in Aboriginal archaeological sites in Victoria, Australia.〔''A Record In Stone: The Study Of Australia's Flaked Stone Artefacts'' by Simon Holdaway, Nicola Stern〕 The material is rarely found and sourced from only one known location at Spring Hill near Lauriston, Victoria.〔(Dr. Ian Nicholls, 'Unusual Newer Volcanics trachyandesite cones in the Gisborne-Woodend and Kyneton-Trentham areas' )〕〔Willman, C. E., Bibby, L. M., Radojkovic, A. M., Maher, S., Haydon, S. J., Hollis, J. D. and C. R. Osborne, C. R. 2002 ''Castlemaine. 1:100,000 Map Area Geological Report''. Geological Survey of Victoria Report 121. Department of Natural Resources and Environment, Melbourne〕
Tachylite is a type of volcanic opaque glass, and is applied to basalts with a glassy matrix that contain scattered small phenocrysts (pyroxene, plagioclase, olivine). Aboriginal artefacts flaked from the material are characterised by a black internal colour, which is very often patinated on the surface to a pale grey. This patina rapidly darkens on contact with the skin, turning as dark as the core. Only a few pieces are generally found in archaeological assemblages in southern Victoria and around Melbourne, apart from at sites near Spring Hill, Kyneton, where it is the most common material.〔Clark, V. 2004.

Tachylite artefacts have been noted in Aboriginal sites in Victoria from at least the 1920s, when W. .H Gill recorded its occurrence in a large stone artefact and camp site complex at Cape Liptrap.
Tachylite has also been identified as an material used in manufacturing flaked stone artefacts in archaeological sites in Europe,〔(Local Supply for Chipped Stone Tools from the Site of Rug BairVasilka DIMITROVSKA ''HAEMUS'' vil 1 2012, Center for Scientific Research Skopje, Macedonia )〕 North America,〔(''A Good Place to Hunt, Data Recovery and Site Stabilization at the La VegaSite (LA 9075), Cibola County, New Mexico'' ) BY STEPHEN C. LENTZ MUSEUM OF NEW MEXICO OFFICE OF ARCHAEOLOGICAL STUDIES〕 and India.〔(''Indian Archaeology 1971-72 a Review'' ), Andhra Pradesh p.11〕
