Jul 23, 2020 · As an intuitive way, the method of limestone tablets (MLT) is often used in dissolution rate calculation and carbon cycle research of carbonate rocks. To clarify the influential factors and spatial suitability of MLT in karst carbon cycle study, 30 MLT test sites in China from north to south were collected and the tablets’ dissolution rate (TDR) was analyzed.
Limestone: Rock Uses, Formation, Composition, Pictures
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of environment is
