Tachylite in Victorian archaeological sites, Aboriginal archaeological site with tachylite artifacts in Victoria, Australia.
Tachylite in Victorian archaeological sites is volcanic glass that appears black and contains small crystals of pyroxene, plagioclase, and olivine within its structure. Fragments and finished tools made from this material have been discovered at multiple locations across southern Victoria.
Archaeological excavations beginning in the 1920s revealed this material was used at many sites over an extended period. Early research by W.H. Gill at Cape Liptrap established the foundation for understanding these tools and their distribution.
The Dja Dja Wurrung people shaped this volcanic glass into weapons and tools that were traded across the region. These items held practical and social value in their exchange networks.
This material develops a distinctive pale grey surface that darkens when touched, making it recognizable in museum and field collections. Fragments are scattered across several locations in the southern region rather than concentrated in one place.
Some of these artifacts remain mysterious regarding their exact origins and how they traveled across the landscape. Studying them reveals clues about ancient movement patterns and connections between distant communities.
