Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

Sediment can also protect the bed from dissolution, even if the stream is undersaturated with respect to calcite [Farrant and Smart, 2011]. The applicability of the dissolution rates presented here is also subject to some uncertainty because many of the HBN sites do not actually deliver water to channels in carbonate rocks.

Additionally, by focusing mainly on calcite (generally sourced from limestone-based rock dust used in coal mines to prevent coal dust explosion), the second part of this study explores basic source apportionment by analyzing mine samples and samples of major dust source materials (such as run-of-mine coal, rock strata, and rock dust products).

In the long term, our target is to reduce calcite in streams to a level that matches other streams unaffected by mining. See the Calcite Management chapter on pages 159 – 183 in the Elk Valley Water Quality Plan and the Calcite chapter in the 2017 Environmental Monitoring Committee Report for more information.

Calcite is common as vein fillings in many rocks in western and central Ohio. Silurian dolomites in northwestern Ohio yield clusters of large crystals ranging from clear to dark brown. Many have a golden color. Celestite – Strontium sulfate. Northwestern Ohio produces crystals of this mineral in colors ranging from white to a beautiful pale blue.

calcite, the most common form of natural calcium carbonate (CaCO 3), a widely distributed mineral known for the beautiful development and great variety of its crystals. It is polymorphous (same chemical formula but different crystal structure) with the minerals aragonite and vaterite and with several forms that apparently exist only under rather extreme experimental conditions.
