Physical properties
Hardness varies from 6 to 7 due to quartz content; color is brown with rust-colored iron oxide matrix; luster ranges from dull to vitreous; clastic texture with rounded pebble inclusions.
Formation & geological history
Formed by the compaction and cementation of rounded gravel and pebble-sized clasts in high-energy environments like river channels or beach fronts over millions of years.
Uses & applications
Used primarily in educational settings, geological collections, and occasionally as decorative landscape aggregate or crushed stone in construction.
Geological facts
The rounded shape of the embedded pebbles indicates they were transported by water over significant distances before deposition and lithification.
Field identification & locations
Easily identified in the field by its distinct visible rounded pebbles or clasts embedded within a finer-grained matrix; found worldwide in sedimentary basins.
