Physical properties
Hardness 7 on Mohs scale, reddish-brown and white coloration, vitreous luster, amorphous crystal structure with angular fragments.
Formation & geological history
Formed through tectonic faulting and fracturing of host rock, followed by hydrothermal precipitation of silica-rich fluids filling the voids.
Uses & applications
Used primarily in lapidary arts, decorative landscaping, and as a geological specimen for collectors.
Geological facts
Breccias are easily recognized by their distinct angular clasts, unlike conglomerates which feature rounded pebbles.
Field identification & locations
Identify in the field by interlocking angular fragments cemented by contrasting mineral veins; found globally in fault zones.
