Shaped like straws, these stalactites grow when water trickles down their centre. Most of the stalactites you see in caves are made from calcium carbonate, according to the Royal Society of Chemistry (opens in new tab). A mineral usually is solid and stable at room temperatures and has a specific formula, or recipe (with atoms occurring in certain proportions) and a specific crystalline structure (meaning that its atoms are organized in regular three-dimensional patterns). Stalactites hang from the ceiling, and stalagmites grow up from the floor. The speleothems with which most people are familiar are stalactites and stalagmites. The quickest growing stalactites are those formed by a constant supply of slow dripping water rich in calcium carbonate (CaCO3) and carbon dioxide (CO2), which can grow at 3mm (0.12 inches) per year. In particular, this analysis would not have been possible without the community databases such as the SISAL database of speleothem oxygen and carbon isotope composition, which contained numerous annually laminated stalagmites. Liquid water slowly drips down from a surface. The most common stalactites are speleothems, which occur in limestone caves. When rain seeps through limestone, the water extracts carbon dioxide gas from the rock. Stalagmites are built by layers of calcite crystals. Newest results.
