Limestone, chalk, and coal are organic sedimentary rocks.
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.
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.
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
Biogenic sedimentary
Chalk and coquina are both examples of bioclastic sedimentary rocks.
Boiclastic sedimentary rocks. Eg Bioclastic Limestone.
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.
I believe it is Bioclastic sedimentary rock--coquina although it was formed by shells of marine organisms.
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.
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.
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.
sedimentary
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.
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.
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.
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.
