Hornfels in Victorian archaeological sites
Hornfels 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〕 A sample of places where it has been found can be seen in the geographic section below.〔Archaeological survey of Aboriginal chert hornfels quarry sites in eastern Tasmania: a report for the Australian Heritage Commission / David Rhodes, Ian Thomas, Melbourne, Vic. Du Cros and Associates, 1994〕
The term has been used for ''...a group of compact, fine-grained, metamorphic rocks that form as a result of contact between sedimentary country rocks and a magma intrusion''. The mineral composition is variable, but commonly contains mica and pyroxene while porphyroblasts of pyroxene, cordierite or andulusite also develop. Sedimentary structures are raly evident due to a high degree of recrystallisation.〔(Archaeological Survey of Gravel Search Area Victoria Highway )〕
