Many lava stalagmites can also evolve on the sidewalls as a result of their complexity with lava shelves, side walks and aprons. The floor?s lava stalagmites situated near the sidewalls are in greater density. At the gradually narrowed ending of the lava tube the terminated lava flow piles up in bigger thickness. That is why the lava flow?s cooling time was longer here than in the other areas of the cave. It results a greater number and size of lava stalactites and stalagmites at the cave?s ending.
The morphology, the occurrence and the numeral density of the several lava dripstone types greatly depend on in which section of the lava tube they formed, but also depend on the morphological diversity of the tube's different sections.
The author investigated and divided several types of lava stalactites and lava stalagmites of the Viogelmir cave into groups according to the location of their formation sites in the lava tube.
