Physical properties

Hardness: 6-7 (Mohs scale); Color: Tan, beige, or light brown; Luster: Dull/Earthy; Crystal structure: Granular/Clastic; Cleavage: None; Specific Gravity: 2.2-2.8

Formation & geological history

Formed through the accumulation and cementation of sand-sized mineral grains or rock fragments. Often formed in desert, river, or coastal environments. Likely Paleozoic or Mesozoic era depending on the specific find site.

Uses & applications

Used primarily in construction (building stone, concrete aggregate), landscaping, and as an aquifer reservoir in the oil and gas industry.

Geological facts

Sandstone is one of the most common types of sedimentary rock and often preserves fossils or trace structures like ripple marks from ancient water currents.

Field identification & locations

Identify in the field by its gritty, sandpaper-like texture and visible grain structure. Look for layering (bedding). Commonly found in dry canyonlands and coastal cliffs.
