Chalk is a very fine‐grained bioclastic limestone composed of accumulations of skeletal debris from tiny marine organisms that drifted down to the ocean floor. All of these “redeposited” limestones could be considered clastic sedimentary rocks, as well as organic sedimentary rocks.Rocks are classified into three main types based on their formation process: igneous, sedimentary, and metamorphic rocks.
