Physical properties

Color: Earthy brown with tan inclusions; Luster: Dull/Earthy; Texture: Granular or clastic; Hardness: Variable (likely 3-6 Mohs depending on cementation); Structure: Fragmented/Massive

Formation & geological history

Formed through the weathering, transport, and deposition of pre-existing mineral or rock particles, followed by lithification through pressure or chemical cementation. Likely derived from local soil or gravel beds.

Uses & applications

Larger deposits are used for road base, concrete aggregate, and general landscaping. Small pebbles are common unintentional debris in residential environments.

Geological facts

Sedimentary rocks cover about 75% of Earth's land surface. This specific specimen appears to be a small clastic fragment that may have been tracked indoors via footwear.

Field identification & locations

Identify in the field by looking for distinct layers (bedding) or grains of sand and silt cemented together. Common in riverbeds, gardens, and under footwear treads.
