What is the most common form of stalactites?

The most common form of stalactites is the calcite stalactite, which forms in limestone caves through the process of mineral deposition. As mineral-rich water drips from the ceiling of a cave, it leaves behind calcium carbonate as it evaporates, gradually building up the stalactite over time. These formations typically hang down from the cave's roof and can vary in size and shape depending on the conditions within the cave. Other minerals can also contribute to stalactite formation, but calcite is by far the most prevalent.
