11 Main Features of Sedimentary Rocks Geology

Mixtures of hematite and limonite produce orange and purple colour. As mentioned earlier sedimentary rocks result from the bonding together and hardening of loose sediments that has accumulated, usually in layers, in water. The sediment is eroded from pre-existing rocks and transported as debris from its source to the place of accumulation.

These cements may impart certain characteristics to the resulting sedimentary rock. For example, rocks cemented with calcite will react to hydrochloric acid. Rocks cemented by hematite have a characteristic red color (the sandstones around Sedona, for example). Rocks cemented by limonite have a characteristic yellow, yellow-brown color.

Sandstone |Composition, Properties, Formation, Uses

Sandstone is a sedimentary rock and one of the most common types of sedimentary rock and is found in sedimentary basins throughout the world. Other minerals that act as cements include: hematite, limonite, feldspars, anhydrite, gypsum, barite, clay minerals, and zeolite minerals. The environment where it is deposited is crucial in
