Should I use dolomitic or calcitic lime? - MSU Extension

Dec 17, 2015· Calcitic lime is derived from deposits of primarily calcium carbonate. Dolomitic lime is derived from deposits of calcium carbonate combined with magnesium carbonate and contains much higher levels of magnesium. The key factors in deciding which of these types of lime should be applied to your soil is the soil pH and magnesium level.

Limestone, Shell, Dolomite | Florida Department of ...

Limestone is a sedimentary rock that is composed primarily of calcite (calcium carbonate, CaCO 3) and dolomite (calcium magnesium carbonate, CaMg (CO 3) 2 ). It can vary in purity, consistency and hardness. The limestone can be a soft chalky material with microfossils, a hard recrystallized mass, a grainy sand-lime mass, or a mass of fossil ...

Limestone vs Dolomite: What Are They, And What's The ...

Jun 20, 2021· Limestone is an occurring type of sedimentary carbonate rock found on Earth's surface. It is formed when crystals of calcium carbonate precipitate out of water containing dissolved calcium. Limestone is composed of minerals such as calcite and aragonite. Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.

What is Dolomitic Limestone? (with pictures)

Dolomitic limestone is a type of rock that includes up to 50% dolomite. Normal limestone is primarily made up of calcite and aragonite, but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization.

The Main Mineral Component Of Dolomitic Limestone

Dolostone is known also as dolomite, or sometimes as dolomitic limestone. Dolomite differs from calcite, the main component of limestone, because it contains the element magnesium (Mg) as well as calcium (Ca).
