Corundum is found as an accessory mineral in the crystalline rucks such as crystalline limestone and dolomites, gneisses, schists as well as in the igneous rock types granite and syenite. Corundum syenites are found in Canada, especially in the Province of Ontario. Rubies have long been mined in Upper Burma both rubies and sapphires arc found near Bangkok, Thailand. Numerous localities in India furnish gem stones of high quality. 

Ill the United Slates, common corundum is found in New York. New Jersey, Pennsylvania. Virginia. North Carolina. South Carolina and Georgia sapphires of gem quality near Helena. Montana, associated with alluvial gold in the Missouri River. From the crystalline limestones and schists of the islands of Naxos and Samos in the Grecian archipelago most of the emery of commerce comes. Other deposits are near Ephesus in the Middle East, and in the mwn of Chester in Massachusetts. The word corundum conies from the Hindu, kurand emery is derived from the Greek name for this substance.

Wollastonite is found in crystalline limestones and is mined where it is sufficiently high in concentration and forms major part of the rock mass. Such places are states of New York and California in the United States, Brittany, Germany, Rumania, and Mexico [13]. 

Wollastonite is the industrially important mineral of the pyroxene mineral group. It occurs chiefly as a metamorphic mineral in crystalline limestones. Wollastonite has... 

Metamorphic rocks were formed by a secondary conversion of igneous and sedimented rocks, due to certain geological tectonic processes. The pressure, temperature, and chemical effects, particularly effects of gases and thermal solutions were the main factors in these conversions. The texture of metamorphic rocks may be characterized by the presence of layers or scales. Typical metamorphic rocks are gneisses, mica-schists, serpentines, crystalline limestones and crystalline dolomites. 

For identical calcining conditions, different limestones may produce quicklimes with measurably different reactivities. While the differences in reactivity may not be significant in most operations, they could affect the suitability of the quicklimes for certain applications (e.g. aerated concrete). There may be several causes of such differences, e.g. rate of calcination, effects of impurities and the microstructure of the lime, (e.g. lime produced from oolitic and coarsely crystalline limestones is more prone to sinter and become less reactive [14.2]). 

Crystalline limestone is a highly crystalline form with a large average grain size (over 50 pm), e.g. marble.

Molybdenite or molybdenum disulfide (M0S2) or molysulfide is a mineral [5] found in granites, syenites, gneisses, and crystalline limestones. A NIOSH (National Institute for Occupational Safety and Health) web site [6] has listed a total of 31 synonyms for molybdenite. The use of molybdenite as a lubricant was apparently recorded in the early seventeenth century by John Andrew Cramer 7]. Chrysler, an automotive manufacturer, was the first to widely use M0S2 grease in the 1960s.

Galun (1963) compared the lichen vegetation of various types of limestone rocks in the Negev of Israel and found the same community whether the rocks were crystal limestone, litographic limestone, flinty limestone, or dolomite, all having different textures and hardness. A similar observation was made by Degelius (1955) with regard to crystalline and noncrystalline limestone except that the crystalline limestone had a richer flora. However, Braun-Blanquet (1951) reported that dolomite is species-poor compared to limestone. 

Apatites form an important series of minerals. They occur as a minor constituent of many igneous rocks, although a few large igneous deposits are known, like the Kola peninsular. Apatite is also present in most metamorphic rocks, especial crystalline limestone. Less well crystallised deposits of rather variable composition, usually referred to as rock phosphates or phosphorite, occur in large deposits, some of which were formed by the reaction between phosphatic solutions from guano and calcareous rock, or precipitated from sea water.
