greensand

Mineral-tinted coastal deposit

Greensand is a type of sedite rich in glauconite, giving it a distinctive greenish color.

It forms in marine environments and appears in geological formations worldwide.

Greensand is valued as a soil amendment and natural fertilizer, slowly releasing potassium and other minerals: We added greensand to the garden beds to improve the clay soil.
