Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ( CaCO3 CaCO 3) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 CaCO 3 ). About 10% of sedimentary rocks are limestones.

The rock cycle describes how rocks on Earth form and change over time. When rocks are pushed deep below Earth’s surface, they can melt to form magma. Magma that reaches Earth’s surface through volcanic activity is called lava. Igneous rocks form when magma or lava cools and solidifies. Weathering breaks igneous and other types of rocks into

Karst sinkholes are naturally enclosed funnel-shaped depressions that are the prime diagnostic features of a karst landscape (Figure 12.2.8). These features can range in size from a few meters in diameter up to a kilometer or so in size. In European literature karst sinkholes are typically called ‘dolines’.

· The rock cycle is a series of processes that create and transform the types of rocks in Earth’s crust. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.

Figure 7. James Hutton is considered the Father of Geology. The concept of the rock cycle was first developed by James Hutton, an eighteenth century scientist often called the “Father of Geology” (shown in figure 7).

· Igneous Rocks form from magma or lava. The two types are intrusive (from magma) and extrusive (from lava). Igneous rocks form through the cooling and solidification of magma or lava.These rocks are distinctly different from sedimentary and metamorphic rocks, which originate from the deposition of material at the Earth’s surface

Marine limestone forms because seawater has high concentrations of two key dissolved chemicals-calcium (Ca ++) and bicarbonate (HCO 3-) ions.
