Chalk is one limestone formed from organic processes. There are others.
result of marine animal and plant remains accumulating and undergoing compaction over time. This process led to the formation of organic limestone, a sedimentary rock rich in calcium carbonate. Millions of years ago, the area might have been underwater, allowing for the accumulation of marine organisms that later contributed to the deposit.
No, limestone is a sedimentary rock formed from the accumulation of marine shells and sediment. It is not a metamorphic rock, but it can undergo metamorphism to form marble under high pressure and temperature.
You are likely to find embedded seashells in limestone, which is a type of sedimentary rock formed from the accumulation of coral, shells, and other organic material.
A sedimentary rock formed from materials that were once living is called organic sedimentary rock. Examples include limestone, coal, and chalk, which are composed of the remains of marine organisms, plants, or other organic matter.
A limestone that contains fossils would be classified as an organic sedimentary rock because the fossils are of biological origin.
A deposit of organic limestone on land likely formed millions of years ago from the accumulation of marine organisms, such as corals, shells, and other calcium carbonate-rich materials. Over time, these organic remains were compacted and cemented together through geological processes, resulting in limestone rock. This type of limestone often indicates that the area was once submerged under water, reflecting ancient marine environments. As tectonic activity raised these deposits above sea level, they became terrestrial formations.

Limestone is not generally referred to as an organic rock. It is primarily composed of calcium carbonate, which is a mineral. However, in some cases, limestone can contain remnants of organic matter such as shells, coral, or other marine organisms, which can give it a slightly organic origin. This is why some people may refer to limestone as an organic rock.

Yes
Sandstone is not an organic sedimentary rock, but limestone is.
Limestone is a chemical sedimentary rock formed from the precipitation of calcium carbonate. It is primarily composed of mineral calcite, which is organic in origin but can also form through inorganic processes. So, limestone is considered both a chemical and organic sedimentary rock.
Limestone made from shells would be an organic sedimentary rock.
Limestone is a type of rock that can be either chemical or organic in nature. Chemical limestone is formed through the precipitation of calcium carbonate, while organic limestone is made up of the remains of marine organisms like shells and coral.
Limestone is a sedimentary rock.
A purely chemical sedimentary limestone would contain no fossil remnants, organic limestone would.
Kaibab Limestone is not an organic sedimentary rock, but classified only as a sedimentary rock. Organic sedimentary rocks form from the remains of carbon rich plant life normally.
