Physical properties
Hardness varies from 3 to 7 depending on mineral content. Features visible parallel bands of grey and dark tones, dull luster, and microcrystalline structure.
Formation & geological history
Formed through the accumulation, compaction, and cementation of mineral particles and sediments in aquatic environments over millions of years.
Uses & applications
Used primarily in landscaping, decorative stone, and as aggregate in construction.
Geological facts
The distinct bands represent changing environmental conditions or sediment sources during the rock deposition process.
Field identification & locations
Found globally in riverbeds, beaches, and sedimentary rock formations; identified easily by alternating color bands.
