Limestone: Who, What, Why, When, and How?

Dolomitic limestones come from natural deposits which contain both calcium and magnesium carbonates. The magnesium content of limestone is especially important where soils are deficient in this essential plant nutrient. If a soil test indicates low magnesium, dolomitic limestone can be used to correct both the nutrient deficiency and …

How to Cut Limestone Blocks

Turn the block over and repeat the process to cut through the other side in the same manner. Depending on the thickness of the block, it may split into two parts after this second cut. Insert a chisel into the cut line of the limestone. Tap the top of the chisel firmly with a hammer to split the remaining limestone apart.

Sinkhole

A sinkhole is a hole in the ground that forms when water dissolves surface rock.Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone. These cracks are called joints.Slowly, as the …

How does weathering affect limestone?

Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is …

How corals build their skeletons

RUTGERS (US) — Scientist have described the process that allows corals to form skeletons, and they say water acidity doesn't affect the process. Those skeletons—destined to become limestones—form massive and ecologically vital coral reefs in the world's oceans. In a publication in Current Biology, Tali Mass and colleagues …
