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.
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.
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.
Chalk is non-clastic, as it is primarily composed of the mineral calcite (calcium carbonate) formed from the remains of microscopic marine organisms such as plankton. These organisms contribute to the fine-grained texture of chalk through chemical precipitation rather than mechanical weathering or erosion.
The word 'clastic rock' is a compound noun, a word for a type of rock, a word for a thing.A noun functions as the subject of a sentence or a clause, and as the object of a verb or a preposition.Example sentences:Clastic rock is rock composed of broken pieces of older rocks. (subject of the sentence)Cathedral Rock in Arizona is made of a clastic rock called sandstone. (object of the preposition 'of')
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.
Chalk and coquina are both examples of bioclastic sedimentary rocks.

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.

Breccias are a relatively common clastic sedimentary rock.
Organic, Clastic, and Chemical
Clastic sedimentary rock.
Clastic material is composed of rock fragments. A clastic rock is composed of smaller rock fragments, such as sand or silt, that have been cemented together.

Different clastic sediments have different textures based on the size, shape, and sorting of the grains they are composed of. The composition of a clastic sedimentary rock will vary depending on the mineralogy of the grains present in the rock. Factors such as the source rock, transportation distance, and depositional environment can all contribute to the differences in texture and composition between clastic sedimentary rocks.
