Physical properties
Hardness varies by clast composition (typically 6-7 for quartz clasts); colors vary; dull luster; clastic texture with rounded gravel and pebble-sized fragments cemented together.
Formation & geological history
Formed by the consolidation and cementation of gravel-sized rounded clasts, typically in high-energy environments like rivers or beaches over millions of years.
Uses & applications
Used locally as low-grade construction aggregate, dimension stone, or decorative landscaping material.
Geological facts
Often referred to colloquially as 'puddingstone' when the matrix and clasts contrast sharply in color.
Field identification & locations
Easily identified in the field by its distinct rounded pebbles and boulders embedded in a finer-grained matrix; found worldwide in sedimentary basins.
