Lithographic limestone is hard limestone
Limestone
Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate . Many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera....

. Geologists use the term lithographic texture to refer to a grain size under 1/250 mm. The term sublithographic is sometimes used for homogeneous fine-grained limestone with a somewhat coarser texture.

Origin

The generally accepted theory for the origin of lithographic and sublithographic limestones is that they were formed in shallow stagnant hypersaline

 and anoxic lagoons. The combination of mild hypersalinity and low oxygen content is believed to have inhibited the formation of microbial mat
Microbial mat
A microbial mat is a multi-layered sheet of micro-organisms, mainly bacteria and archaea. Microbial mats grow at interfaces between different types of material, mostly on submerged or moist surfaces but a few survive in deserts. They colonize environments ranging in temperature from –40°C to +120°C...

s and prevented the invasion of bottom dwelling organisms. Microbial mats and bottom dwelling organisms would have left fossils, and bottom dwelling organisms would have churned the accumulating sediment, producing a less homogeneous rock. Stagnancy was required to avoid churning or sculpting of the sediment by currents or wave action.

. This quarry was the only commercial source of lithographic stone in the United States at the turn of the 20th century. Unlike the Solnhofen stone, Kentucky lithographic limestone was slightly dolomitic, and it was judged to be competitive with Solnhofen stone for some purposes, but not for the highest quality work. This stone source was sub-Carboniferous (Mississipian). In 1917, the Brandenburg quarry was judged the most important source of Lithographic stone in the United States. Prior to 1916, the output of the Brandenburg quarry was small, but in 1916, as World War I

 who reported that stone from two layers in the Lithograph City quarry was excellent for lithography and finer grained than the finest Solnhofen stone. Lithograph City was an important source of lithographic stone in the United States during World War I, but the quarries closed as metal printing plates replaced stone. In 1918, the Devonian Products Company took over the operation, focusing on the production of crushed rock and renaming the town Devonia. By 1938, the town had disappeared.
