Bioclasts are skeletal fossil fragments of once living marine or land organisms that are found in sedimentary rocks laid down in a marine environment—especially limestone varieties around the globe, some of which take on distinct textures and coloration from their predominate bioclasts—that geologists, archaeologists and paleontologists use to d...

Skeletal fragments, also known as bioclasts, can be whole fossils or broken fragments of organisms, depending on current and wave strength as well as depositional depth. The content and texture of the bioclast component in any carbonate will vary noticeably as a function of both age (due to evolution) and… Read More

The meaning of BIOCLAST is a fragment of biological origin (such as a shell fragment or fossil) occurring in sedimentary rock. How to use bioclast in a sentence.

A bioclast is a grain (allochem) within a carbonate rock derived from the remains of the hard parts of carbonate secreting organisms. Common bioclasts are derived from molluscs, bryozoans, corals, echinoids, crinoids and forminafera.

Jan 1, 2013 · Bioclasts, a.k.a. fossils, shells, skeletal particles, biotics, etc., are an important component of many limestones, shales, and sandstones and are volumetrically the dominant to exclusive particulate building block of many limestones. They are typically the major tool for age determination and paleoecological information.

Jan 7, 2022 · Molluscan bioclasts are important components of tropical, and cool-temperate water limestones. Bioclasts are probably the most important components of Phanerozoic limestone frameworks (grainstones, rudstones, packstones, floatstones).

Bioclastic sediment also occurs mainly between 50 and 80m water depth as patches or ribbons with a distinct pattern of low (finer grained sediments, mainly gravelly sand) and high backscatter (coarser grained sediment; You might find these chapters and articles relevant to this topic.
