Stalactite Limestone stalactites [edit]. The most common stalactites are speleothems, which occur in limestone caves. They form through deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions. stalactite is not necessarily a speleothem, though speleothems are the most common form of stalactite because of the abundance of limestone caves.

Flowstone Flowstones are composed of sheetlike deposits of calcite or other carbonate minerals, formed where water flows down the walls or along the floors of a cave.[1] They are typically found in solution caves, in limestone, where they are the most common speleothem. However, they may form in any type of cave where water enters that has picked up dissolved minerals. Flowstones are formed via the degassing of vadose percolation waters. Flowstone may also form on manmade structures as a result of calcium hydroxide being leached from concrete, lime or mortar.

Varicose Veins What are Varicose Veins? Veins are blood vessels that return deoxygenated blood from the outer parts of the body back to the heart and lungs. When veins become abnormally thick, full of twists and turns, or enlarged, they are called varicose vein. This happens most commonly in the veins in the legs and thighs. 1  The thickened, twisting or dilated parts of the vein are called varicosities. 2  Varicose veins can form anywhere in the body, but they are most often located in the legs. 3  Varicose veins tend to be inherited, and become more prominent as a person ages.
