Physical properties
Hardness of 7 on the Mohs scale, dull to waxy luster, conchoidal fracture, greyish-brown color with iron oxide staining (patina).
Formation & geological history
Formed through the replacement of limestone or chalk by microcrystalline silica during diagenesis in marine environments, often shaped by human artifice.
Uses & applications
Historically used for prehistoric stone tools such as handaxes, scrapers, and cutting implements; now of significant archaeological and collector value.
Geological facts
This specimen exhibits characteristics of a prehistoric lithic artifact (handaxe or celt), showing intentional shaping and flaking alongside weathering and patina.
Field identification & locations
Found in regions with ancient human activity near flint-bearing sedimentary deposits; identified by conchoidal fracture patterns and anthropogenic working edges.
