A common stalactite found seasonally or year round in many caves is the ice stalactite, commonly referred to as icicles, especially on the surface. [12] Water seepage from the surface will penetrate into a cave and if temperatures are below freezing, the water will form stalactites. They can also be formed by the freezing of water vapor. [13]
Straws (stalactite precursors) in Gardner's Gut. Soda straw. A soda straw (or simply straw) is a speleothem in the form of a hollow mineral cylindrical tube. They are also known as tubular stalactites. Soda straws grow in places where water leaches slowly through cracks in rock, such as on the roofs of caves.
Internal water pulses from the straw (into the drop) and air movement around the suspended solution drop, can cause the rafts to spin swiftly around the drop surface. [ 10 ] [ 11 ] [ 8 ] If there is almost no air movement around the suspended drop, then after approximately 12 minutes or more, the micro rafts may join up and form a latticework ...
Significant air movement will cause the rafts to become scattered and spin turbulently around the drop's surface. This turbulent movement of calcite rafts can cause some to shear off the drop's surface tension and be pushed onto the outside of the straw stalactite, thus increasing the outside diameter and creating minute irregularities.

A stalagmite (UK: / ˈ s t æ l ə ɡ ˌ m aɪ t /, US: / s t ə ˈ l æ ɡ m aɪ t /; from Greek σταλαγμίτης (stalagmítēs); from Ancient Greek σταλαγμίας (stalagmías) 'dropping, trickling' and -ίτης (-ítēs) 'one connected to, a member of') [1] is a type of ...
Stalagmites: They are formed as the water drops, which carry acid carbonate, fall on the ground under a stalactite. When a stalactite meets a stalagmite, we have a ...
Drip rate counting and trace element analysis of the water drops record short-term climate variations, such as El Niño–Southern Oscillation (ENSO) climate events. [9] Exceptionally, climate proxy data from the early Permian period have been retrieved from speleothems dated to 289 million years ago sourced from infilled caves exposed by ...
The cannula of a stalactite is formed by a series of very small rhombohedra which interpenetrate each other. If, as consequence of several causes, the cannula is perforated on the side, water will come out through that opening and will create an aggregate of other rhombohedra on the side. The third one is the presence of any impurities in the ...
