No. Stalactites are formed of limestone that is dissolved in slightly acidic ground water that precipitates and deposits a fraction of the dissolved limestone where the solution drips from the roof of a cavern to the floor. On the floor, below the stalactite, a stalagmite forms. The stalactite grows downward, and the stalagmite grows upward. This whole process requires a limestone cavern.

What rock formations hang in caves?
Stalactites and stalagmites are rock formations that hang in caves. Stalactites are formed from water dripping from the ceiling and gradually depositing minerals that build up over time. Stalagmites, on the other hand, form from water dripping from the stalactites and building up on the cave floor.
Can precipitate calcite be found in caves?
Yes, precipitation of calcite can occur in caves through a process called cave formation or speleothem formation. This happens when dissolved calcium carbonate in water drips or flows into the cave, allowing calcite to crystallize and accumulate as stalagmites, stalactites, and other cave formations.
What is a dripstone deposit?
A dripstone deposit is a mineral deposit formed by dripping water in caves, resulting in the gradual buildup of mineral deposits such as stalactites, stalagmites, and other formations. These formations are commonly found in limestone caves and are created by the precipitation of minerals from the dripping water.
What rock formations hang from the celing of some caves?
This would be called a precipitate. A precipitate is an insoluble solid that forms out of a solution when it becomes supersaturated. Calcite precipitates are often found in limestone caves in the form of stalagmites.
What are the formations called that are found in limestone caves?
The main ones are Stalactites (growing down from the roof) and Stalagmites (up from the floor). The central letters, C for ceiling and G for ground, form a useful mnemonic for remembering which is which. They are formed of precipitated calcite, as are other, related formations like flowstone.
Where is the precipitate calcite commonly found to create formations in the ground?
Calcite precipitate commonly forms in caves, particularly in limestone caves, where it can create stalactites, stalagmites, and other mineral formations. This process occurs when water containing dissolved calcium carbonate drips from the cave ceiling and leaves behind calcite deposits as the water evaporates.
Do stalactites grow up or down?
Stalactites grow down from the ceiling of caves or other structures. They are formed by the dripping of mineral-rich water that leaves behind deposits of minerals, typically calcium carbonate, over time.
Are stalactites a type of crystal?
No, stalactites are not a type of crystal. They are formations that hang from the ceiling of caves, formed by mineral deposits dripping down over time. Crystals, on the other hand, have a more defined geometric structure and can form in a variety of environments.
Do stalactites rise from floor or hang from ceiling of limestone caves?
Stalactites hang from the ceiling of limestone caves. They form as mineral-rich water drips from the ceiling and deposits mineral formations, which over time build up into icicle-shaped structures pointing downwards. Stalagmites, on the other hand, rise from the cave floor.
Where can you find stalactites and stalagmites other than caves?
Stalactites and stalagmites can also form in underground tunnels, lava tubes, mines, and man-made structures like abandoned buildings and tunnels. They require a source of water to form as minerals are deposited over time.
What minerals are stalactites made of?
Stalactites are primarily made of calcite, a mineral form of calcium carbonate. Other minerals commonly found in stalactites include aragonite and gypsum. These minerals are deposited on cave ceilings by dripping water, creating the elongated formations we know as stalactites.
Where would you find stalagmites stalagmites?
In caves formed in limestone - as are most of the world's caves although not all such caves contain stalagmites and stalactites. They are precipitations of calcite dissolved from the host limestone by carbonic acid - rain water acidified by atmospheric carbon dioxide dissolved in it.
