Abstract. Economically viable limestone deposits are mostly formed by calcite minerals, and these minerals are widely used in manufacturing of cement, mortar, fertilizer and flux for smelting of iron ores, and mapping of such deposits is significant and important in scientific research.
S.K. Haldar, Josip Tiljar, in Introduction to Mineralogy and Petrology, 2014. 8.1.3 Mineral and Rock Deposit Mineral deposits are aggregate of mineral andor group of minerals in an unusually high concentration. The mineral deposits must have three-dimensional configuration that includes shape in plan and sectional view, continuity in strike and depth to represent volume, and size .
In recent years social and environmental pressures have been threatening the supply of limestone aggregates in the urban areas of Jamaica. Faced with the problem of providing low price aggregates without creating intolerable environmental problems, a study made of the aggregate industry in the Kingston area showed that one possible solution was the relocation of all quarries in specially zoned .

Limestone has two origins 1 biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera and 2 mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.
Limestone vs Chert Characteristics. Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Limestone vs Chert characteristics assist us to distinguish and recognize rocks.
