Which type of sedimentary rock is limestone?
Limestone is a type of chemical sedimentary rock that is predominantly composed of the mineral calcite or aragonite. It forms primarily from the accumulation of shell, coral, algal, and fecal debris. Limestone often contains fossils and can vary in color and texture.
Is limestone chemical sedimentary rock?
It can be. Limestone can be derived from precipitating minerals, in which case it is a chemical sedimentary rock. It can also be formed from the remains of marine organisms, in which case it is described as a bioclastic sedimentary rock, a form of detrital rock.
What is a bioclastic sedimentary rock composed of organic material?
A bioclastic sedimentary rock is composed of fragments of organic material, such as shells, coral, and plant remains, that have accumulated and lithified over time. These rocks form in environments where biological activity is prominent, like shallow marine settings. Common examples include limestone, which often contains fossilized corals and shell fragments, and coal, which is derived from plant material. The composition and texture of bioclastic rocks can provide insights into past environmental conditions and biological activity.
How can you determine if a rock is bioclastic?
You can determine if a rock is bioclastic by examining it for the presence of broken fragments of shells, corals, or other fossils that make up the rock. These fragments will indicate that the rock was formed from the remains of once-living organisms, and therefore, it is bioclastic in nature. Additionally, bioclastic rocks often have a visible organic texture or structure that is characteristic of the original organisms from which they formed.
What is the texture of all inorganic land derived sedimentary rocks?

What is a example of an bioclastic rock?
Chalk and coquina are both examples of bioclastic sedimentary rocks.
What rock is at least partly biologically produced?
Boiclastic sedimentary rocks. Eg Bioclastic Limestone.
What is bioclastic texture?
Bioclastic texture refers to a sedimentary rock texture composed of broken fragments of shells or other skeletal material. These fragments are typically visible within the rock and are often cemented together by mineral matter. Bioclastic textures are common in rocks formed from marine environments.
Many caves in the eastern US were formed with what kind of sedimentary rock that contained remains of ancient marine life?
I believe it is Bioclastic sedimentary rock--coquina although it was formed by shells of marine organisms.
How does bioclastic rock form?
Bioclastic rocks form when organic material, such as shells or calcareous skeletons of marine organisms, accumulate and are compacted over time. These materials are often cemented together by minerals, forming a solid rock. Factors such as wave action, currents, and biological activity contribute to the formation of bioclastic rocks.
Cemented shells of marine organisms form which kind of sedimentary rock?
The cemented shells of marine organisms form limestone, which is a type of sedimentary rock. Limestone is predominantly composed of the mineral calcite and can contain fossilized remains of shells and other marine organisms.
What makes a clastic rock different from a bioclastic rock?
A Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. A Bioclastic rock is a clastic rock but the fragments are not of preexisting rock but of organic shell and or bone fragments.
Is limestone classified as a granite or a sandstone?
Limestone is not classed as either a granitoid or a sandstone rock. Limestone is a sedimentary rock, either chemically precipitated or bioclastic in origin. Granite is a plutonic igneous rock, and sandstone, although sedimentary, is formed from the cementation of sand-sized particles of eroded rock.
What kind of sedimentary rock is formed when sediment is buried compacted and cemented?
The sedimentary rock formed by burying, compacting, and cementing sediment is called "clastic sedimentary rock." Examples include sandstone, shale, and conglomerate, which are composed of fragments of pre-existing rocks or minerals that have been lithified through the process of compaction and cementation.
Shale is an example of this type of rock?
sedimentary

What is a rock formed from crushed shells and coral?
A rock formed from crushed shells and coral is known as coquina. Coquina is a sedimentary rock that is composed of fragmented shell and coral debris cemented together. It is commonly found along coastlines and can have a characteristic porous appearance.
