Stalagmiitti

Stalagmiitti is a type of speleothem, which are mineral formations found in caves. Specifically, a stalagmite is an upward-growing mound or pillar of mineral deposits that forms on the floor of a cave. They are created by the continuous dripping of water that contains dissolved minerals, most commonly calcium carbonate. As the water droplets fall from the ceiling, they deposit small amounts of these minerals. Over long periods, these deposits accumulate, gradually building up from the cave floor.

The formation process is slow, often taking thousands of years to create significant structures. The minerals are typically dissolved from the rock above the cave, such as limestone. When the water reaches the cave air, carbon dioxide is released, causing the calcium carbonate to precipitate out of the solution. This precipitation occurs drop by drop, leading to the characteristic conical or cylindrical shape of a stalagmite.

Stalagmites are distinct from stalactites, which are similar mineral formations that hang down from the cave ceiling. Stalactites are formed by the same process but grow downwards. In many caves, stalagmites and stalactites can grow towards each other and eventually merge to form a complete column. The appearance and size of stalagmites can vary greatly depending on the mineral content of the water, the humidity, and the airflow within the cave. They are a common and fascinating feature in limestone caves worldwide.
