Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3)
Calcium carbonate has been used extensively throughout history in construction and agricultural applications and it is still one of the worlds most widely used materials.
At South Queensland Lime all of our source material is 98.7% pure Calcium Carbonate and comes directly from the local Texas beds found in the region.
