Limestone has many industrial uses and can be used as mined or processed into a wide variety of products. It is the raw material for a large variety of construction, agricultural, environmental, and industrial materials. Limestone is used in construction almost everywhere. The table below includes specific environments where various types of sediments are deposited and common rocks, structures, and fossils that aid in deducing the depositional environment from examining a sedimentary rock outcrop. Although this is not a complete list, it is a good introduction to depositional environments. Continental. Transitional.Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.situ Collections: Alpine and rock garden plants in limestone environment. • Giardino Botanico e Arboreto appenninico del Parco Nazionale d'Abruzzo, via Santa Lucia, 67032 Pescasseroli ABRUZZO (AQ) (Central office, viale delle Medaglie, d'Oro 141, 00136, Rome.
