Chemistry:Hornfels in Victorian archaeological sites
From HandWiki
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.[1] A sample of places where it has been found can be seen in the geographic section below.[2]
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 rarely evident due to a high degree of recrystallisation.[3]
