The melted water trickles towards the ground and re-freezes before it hits the floor. What is a Stalagmite? Ice stalactites are probably the most common type of stalactite. A stalactite is an icicle-shaped formation that hangs from the ceiling of a cave and is produced by precipitation of minerals from water dripping through the cave ceiling.

When a drop finally hits the cave floor, it deposits even more calcite there, this time in an unassuming mound. The term "stalactite" was coined in the 17th century by the Danish Physician Ole Worm,[17] who coined the word from the Greek word (stalaktos, "dripping") and the Greek suffix - (-ites, connected with or belonging to).

One of the longest stalactites viewable by the general public is in Pol an Ionain (Doolin Cave), County Clare, Ireland, in a karst region known as The Burren; what makes it more impressive is the fact that the stalactite is held on by a section of calcite less than 0.3m2 (3.2sqft). Laminated stalagmites are predominantly found where precipitation has a definite wet or dry season, and no laminated stalagmites have been reported for sites with no precipitation seasonality. Stalactites form exclusively on ceilings as dissolved minerals drip down in the form of mineralized water (Gauri, n.d.). Scientists from the University of Cambridge and the University of Arizona used photographs, maths, and physics to work out why icicles are pointy.

Another type of stalagmite is formed in lava tubes while molten and fluid lava is still active inside. In other words, stalactites form on the roofs of caves and dangle downward like rocky icicles. Stalagmites grow upwards from cave floors. [2] Stalagmites in lava tubes are rarer than their stalactite counterparts because during their formation, the dripping molten material most often falls onto still-moving lava flow which absorbs or carries the material away. But I eventually caved. Ice stalactites can also form under sea ice when saline water is introduced to ocean water.
