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 …

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 …

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 …

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.

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant …

Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate, CaCO 3).It makes up about ten percent of the total volume of all sedimentary rocks. A unique feature of this rock is that its main constituent, calcite, is produced chiefly by shell-producing and coral-building living organisms.Numerous caves, gorges, sinkholes, …
