Quarry

Portland Quarry produces quality aggregates from the natural Malmesbury Hornfels deposits in our quarry. Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism.
