Cave Popcorn refers to knobs of calcite that form where water seeps through pores in limestone, creating clusters that resemble popcorn, peas, or grapes.After precipitation of gypsum, the brine is both enriched in Mg relative to Ca and has a higher density. If the brine then enters the groundwater system and moves downward into buried limestones. This Mg-rich brine then reacts with the calcite in the limestone to produce dolomite. Mixing of Seawater and Meteoric Water.As the calcite grows from the tip at various angles, interesting twisted shapes result. Flowstones. Flowstone forms from layers of calcite deposited when thin films of water flow down walls and across cave floors. Some resemble 'frozen waterfalls'. Flowstone often forms over gravel and silt left behind by underground rivers.Calcite readily dissolves in diluted hydrochloric acid or vinegar. It is also slightly soluble in water, which causes dissolution and reprecipitation of calcite along fissures in limestone rocks. These processes lead to the formation of karst landscape with famous caves and dripstones. Similar processes cause the corrosion of concrete.Iceland spar is a clear, colorless, transparent variety of calcite that exhibits strong double refraction or birefringence. It is said the Vikings used Iceland's spar for navigation. Calcite is also a component in many rocks such as limestone, marble, and carbonatite. Its name comes from the Greek word calyx which translates to “lime” and ...Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis. Limestone also forms as a deposit in caves from the precipitation of calcium carbonate.

Like any other type of phytoplankton, Coccolithophores are one-celled plant-like organisms that live in large numbers throughout the upper layers of the ocean.
