· Chalk is a type of limestone that contains mostly shells from marine animals. During the 1700s, limestone was used for lithography which is when pictures are drawn on stones and then copied to other stones. Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock.

2013-6-9 · materials include marble, chalk, marl, shell deposits, blastfurnace slag and alkali waste. The overburden to limestone deposits is also used frequently as a source of silica, alumina and iron. Other mineral components (such as iron oxide wastes, silica sand, etc) are sometimes used to blend into the raw material mix to optimise the chemistry.
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone …
