Green Sandstone Bracelet

Sandstone is typically a well-cemented rock, meaning that the sand grains are held together by some type of mineral cement, such as silica, calcium carbonate, or iron oxide. The degree of cementation can vary, and this can affect the strength and durability of the rock. Sandstone can be porous, allowing it to hold and transmit fluids, such as water or oil, and this property makes it an important reservoir rock in the petroleum industry.
