High-calcium limestone is used to make Portland cement that is used in concrete and mortars. Portland cement is produced by burning a slurry of finely crushed, high-calcium limestone, clay, sand, and a small amount of iron ore in a cement kiln. The pelletal material exiting the kiln is called "clinker." Gypsum is added, and the clinker ...

The Benefits of Using Limestone. Posted on . Aug 10, 2012 by Valorie. Versatility. Limestone is a rock with a variety of uses. Most limestone is crushed and used as a construction material. Other uses include: road base, railroad ballast, concrete and cement when it's fired in a kiln with crushed shale. Pure limestone is nearly white in color, but most of the limestone used …
Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make up the marble. Metamorphism occurs in limestone when the ...

Some shale is high in calcium content because of the fossils they possibly house. Shale that has a high content of alumina is used to manufacture cement. Shale that has a high content of natural gas has been recently used as an energy source. Quartz and other minerals are typically found in shale ...
Crain's Rule #7: PE below 1 is coal, near 2 is sandstone, near 3 is dolomite or shale, and near 5 is limestone or anhydrite. The high density (negative density porosity) of anhydrite will distinguish anhydrite from limestone. High gamma ray will distinguish shale from dolomite.
Economic Importance. Clay and shales are necessary for modern society as we know it.

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).
Shale: Shale,, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles.
