Where is Limestone found On continental crust, limestone is found virtually anywhere an ancient sea existed. The limestone could be exposed at the surface due to erosion or roadcuts, or could be buried hundreds of feet underground, covered by other sedimentary rock or unlithified sediments.

However, limestone strata in the Montréal area were not thick enough to provide sufficient large blocks, which favoured the development of the rich deposits of Saint-Marc-des-Carrières, where the first extraction work began in 1835.

This paper will essentially update the information that is already known and published on t he limestones of the Province of Quebec. The excellent report by M. F. Goudge (1935)m is difficult to improve upon and the areas of limestone quarrying are generally t he same as they were at the time of Goudge's report.

Limestone is typically found in warm, shallow water areas and is usually a shade of tan or bluish gray. Volcanic ash beds are formed from the eruption of a volcano. California, Utah, Nevada, Iowa, and Arizona are all known for their geodes, but you can find geodes in most other states as well.

The MRNF (Quebec Province's department of natural resources) provides the following description : The strata which dip 3 degrees eastward belong to the Trenton Group (Tetreauville Formation). The compact, bluish-black limestone is in very regular beds up to 15 cm thick, separated by clay interbeds.

Apatite or "phosphate" is found in Eastern Ontario and Western Quebec in bunches, pockets, or large vein-like masses associated with mica, pink calcite, pyroxene and scapolite. These deposits are found in dikes of pyroxenite, particularly at their contacts with gneiss, mica schist, and crystalline limestone.

This midwestern fluorescent beauty consists of pockets of scalenohedral calcite crystals on a limestone matrix, and was collected from the Pugh Quarry in Custar, Wood County, Ohio. Under all UV wavelengths the calcite fluoresces bright blue/white. The underlying limestone is also fluorescent, providing an aesthetically contrasting tan/cream background.

Although the Marbleton plant, located in Quebec's Easter Townships region, is one of the oldest lime production facilities in North America, it is equipped with modern and efficient production equipment. For limestone, the plant draws on an extensive 'ocean-reef' deposit that has been quarried since 1824.

Brown limestone. Brown limestone is quarried in the Saint-Marc-des-Carrières area of the Capitale-Nationale Region. The stone is a brownish-grey fossil-bearing limestone belonging to the Deschambault Formation (Trenton Group) (Clark and Globensky, 1975).It is primarily used to produce dimension stone (cut-to-size, slabs, and cut stone) and landscaping stone.

Acid mine tailings may affect several environmental matrices. Here, we aimed to stabilize acid-generated mine tailings using several alkaline and cementitious amendments, which were tested in columns for 361 days. The alkaline amendments consisted of 10 and 20 wt.% limestone, while the cementitious amendments consisted of different binders at a total dosage of 5 wt.% binder.
