Physical properties
Red, earthy to dull luster, solid structure, hardness depends on composition (7 for jasper, lower for sandstone).
Formation & geological history
Formed by sedimentary processes, typically colored red by the presence of iron oxides (hematite).
Uses & applications
Used in landscaping, occasionally as a semi-precious stone if jasper, or as aggregate.
Geological facts
The vibrant red color is highly characteristic of iron oxidation in arid or ancient environments.
Field identification & locations
Identify by its distinctive red color and earthy texture. Commonly found in riverbeds, beaches, and desert regions.
