In the description of a fosil site, I ran into the term "lumachelic limestone". Does anybody know, what this means?
Baluncore said:Does it look like broken fragments of macaroni?
A lumachelic limestone is a type of sedimentary rock that is composed of primarily calcium carbonate and formed from the accumulation of shells, coral, and other marine organisms. It is characterized by its light color and often contains visible shell fragments.
Lumachelic limestone is formed through the process of sedimentation, where the remains of marine organisms settle and accumulate on the ocean floor. Over time, these sediments are compressed and cemented together to form solid rock.
Lumachelic limestone is typically light in color, ranging from white to beige, and often contains visible shell fragments. It is a soft and porous rock, making it easy to cut and shape. It also has a high calcium carbonate content, making it a good source of lime for agricultural and industrial use.
Lumachelic limestone is commonly found in shallow marine environments, such as coral reefs, lagoons, and tidal flats. It can also be found in inland areas where ancient oceans once existed, such as the Great Plains region of the United States.
Lumachelic limestone has a variety of uses, including as a building material for construction, a source of lime for agriculture and industry, and as a decorative stone. It is also used in the production of cement, as a filler in paper and plastics, and as a source of crushed stone for roads and driveways.
