To fill this knowledge gap, we surveyed plantThe calcium carbonate present in the limestone reacts easily with hydrogen ions present in acids. Hydrogen ions break down the chemical composition of calcium carbonate to produce carbon dioxide, water, and other chemical compounds. This makes limestone structures, man-made or naturally occurring, crumble in acid rain.Hornfels is a fine-grained metamorphic rock that was subjected to the heat of contact metamorphism at a shallow depth.

The type of rock that the fragments were produced from is often used as an adjective when referring to the rock. Some examples: sandstone breccia, limestone breccia, granite breccia, chert breccia, basalt breccia, and others. Durability (essentially based on mineral composition and hardness and past performance), strength, and the ability of the stone to take a polish are other important selection criteria.

It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

This limestone is composed of tiny spheres called ooids. Calcium carbonate settling out of the seawater coated tiny bits of shell and sand in layer upon layer. The resulting ooids, or spherical grains of limestone, were pushed by longshore currents into the linear Atlantic Coastal Ridge during the Pleistocene.Limestone is primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities. The purity of limestone depends on the geological conditions under which it formed.Dolomite is very similar in composition to limestone; the main difference between the two is that dolomite contains magnesium and limestone does not. Other rock types that are found with limestone in these formations include shale, black shale, chert, marble, siltstone, and phyllite.
