What is A deposit of organic limestone on land probably formed millions of years ago as?

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.


A deposit of organic limestone on land probably formed millions of years ago as a?

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.


Why is limestone called a organic rock?

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.

Is limestone an organic and chemical sedimentary rock?

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.


Is limestone from shells chemical organic or clastic?

What rock can be a chemical or organic 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.


Is limestone a igneous rock?
