SPELEOTHEMS: Stalactites, stalactites, curtains (draperies in US caving), straws (fine tubular stalactites - 'soda straws' in US), flowstone, gour pools (I think 'rimstone' pools, ditto), cave pearls, helictites (aka 'erratics' but rather unwisely because that is already a definite geological term for a boulder left far from source by a glacier.
They are all of calcite, crystalline calcium carbonate.
Caverns form in the zone of saturation because flowing water dissolves rock to create voids. Dripstone features form in the zone of aeration because water drips through the air and leaves behind minerals when it evaporates, slowly building up formations like stalactites and stalagmites.
Carbonic acid plays a key role in the formation of dripstones in caves. When carbonic acid in rainwater interacts with limestone, it creates a chemical reaction that dissolves the limestone and forms caves. As the water drips through the cave, it leaves behind mineral deposits that accumulate over time to form dripstones like stalactites and stalagmites.
Dripstone formations, such as stalactites and stalagmites, are primarily composed of calcium carbonate minerals like calcite. These minerals are deposited as water containing dissolved minerals drips from the ceiling of a cave, leaving behind layers of mineral deposits over time. Other minerals and organic materials can also contribute to the formation of dripstones.
Calcite hardens to form cave features through a process called mineral deposition. When water containing dissolved calcium carbonate drips into a cave, it loses carbon dioxide as it enters the lower-pressure environment, causing the calcium carbonate to precipitate and form solid calcite deposits. Over time, these deposits accumulate to create formations like stalactites, stalagmites, and other speleothems, contributing to the cave's intricate structure. This process is ongoing, with new layers building up as long as the conditions remain favorable.

How does dripstone form
A dripstone column forms when mineral-rich water drips from a cave ceiling and accumulates on the cave floor, creating a stalagmite. Over time, as more dripping water flows down the stalactite and onto the stalagmite, they join together to form a column.
A dripstone column forms when a stalactite and and a stalagmite join together.
Caverns form in the zone of saturation because flowing water dissolves rock to create voids. Dripstone features form in the zone of aeration because water drips through the air and leaves behind minerals when it evaporates, slowly building up formations like stalactites and stalagmites.
Calcite is the primary mineral found in dripstone formations such as stalactites and stalagmites. It is a common form of limestone that is formed from the precipitation of calcium carbonate dissolved in water.
Stalactites are the icicle-shaped features that form on cave ceilings. They are composed of mineral deposits that accumulate as water drips from the cave ceiling and evaporates, leaving behind a small amount of mineral material.
Carbonic acid plays a key role in the formation of dripstones in caves. When carbonic acid in rainwater interacts with limestone, it creates a chemical reaction that dissolves the limestone and forms caves. As the water drips through the cave, it leaves behind mineral deposits that accumulate over time to form dripstones like stalactites and stalagmites.
Those are stalagmites. It has a 'g' in it, so think of 'Ground' to help you remember.The deposits hanging from the roof of the cave are stalactites. It has a 'c' in it, so think of 'Ceiling'. They also Stick Tight to the ceiling.
The dripstone that grows down from the roof of a cavern is called a stalactite. Stalactites are formed by mineral-rich water dripping, leaving behind deposits of minerals such as calcite. Over time, these deposits build up and create elongated structures hanging from the cave ceiling.
Dripstone columns form in caves when mineral-rich water drips down from the ceiling, leaving behind mineral deposits that accumulate and build up over time. As the water drips and evaporates, it leaves behind small amounts of minerals like calcium carbonate, which gradually solidify into stalactites and eventually connect with stalagmites to form a column.
The features sea stack, sea headland, cliff, sea arch, and sea cave all form from continuous wave erosion over a long period.
