  • Limestone an overview ScienceDirect Topics

    Limestone areas throughout the Indonesian archipelago originate from jurassic, cretaceous, tertiary and quarternary times. Forests over limestone are usually a mosaic of rich and poor growth due to free-draining, steep slopes, water stress, high concentrations of calcium and magnesium, richer soils between jagged peaks and pinnacles.Limestone,The process is called calcination and works by driving off carbon dioxide from the calcite, forming calcium oxide (quicklime). Limestone used as a source of nutritional calcium is simply ground into a powder, mixed with other supplements and binders, and reformed into pills or capsules.
