Limestone Mauve

Limestone

Limestone is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life.

Mauve

Mauve is a pale purple color named after the mallow flower. The first use of the word mauve as a color was in 1796–1798 according to the Oxford English Dictionary, but its use seems to have been rare before 1859. Another name for the color is mallow, with the first recorded use of mallow as a color name in English in 1611.
