The limestone, or more accurately its calcium carbonate,has been dissolved from the rock above, in the joints through which the ground-water passes before dripping into the cave.
The mineral is then precipitated in the cave air as Calcite, to form a Stalactite on the celing, and a Stalagmite on the floor below.
A "column" is simply a stalactite and stalagmite that have met.
A stone column rising from the floor of a cave is called a stalagmite. It forms over thousands of years as mineral-rich water drips from the ceiling and deposits minerals on the cave floor, gradually building up into a column shape.
A limestone tower is a tall structure typically made of limestone rock that has been naturally eroded over time, creating a narrow, vertical column-like formation. These towers are often found in areas where limestone deposits have been subjected to erosion by wind, water, and other natural forces. Limestone towers can be found in various parts of the world, including places like China's Zhangjiajie National Forest Park and the limestone karst landscapes of Southeast Asia.
A stalactite is a structure that hangs from the ceiling of a cave and is formed by minerals dripping down, while a stalagmite is a structure that rises from the floor of a cave and is formed by minerals deposited from drips falling from the stalactite. When a stalactite and a stalagmite eventually meet and grow together, they form a column.
Trajan's Column is estimated to weigh around 1,110 tons.
There are 120 scenes depicted on the column of Marcus Aurelius in Rome. These scenes spiral around the column and depict various military campaigns and battles of Emperor Marcus Aurelius.

The stone column that supports the ceiling is crumbling away.
A cave column is a mineral formation found in caves where a stalactite from the ceiling and a stalagmite from the floor meet and grow together, eventually forming a column. These columns can vary in size and shape depending on the specific conditions in the cave where they form.
Stalactites hang from the ceiling of limestone caves, while stalagmites rise from the floor. Stalactites form as mineral-rich water drips from the cave ceiling, leaving behind deposits of minerals that accumulate over time. Stalagmites form as the drips fall to the floor and build up mineral deposits in a cone shape.
The difference in thickness between the limestone columns could be due to variations in sedimentation rates, tectonic activity, or erosion. Factors such as local geology, depositional environment, and the presence of faults or fractures in the rocks can all influence the thickness of sedimentary layers.
stalagmites are on the cave floor, stalactites are on the cave roof. stalagmites are mighty like Hercules, they hold the ceiling up. +++ An easy mnemonic: "c for ceiling, g for ground". Another is "Stalagmites might reach the roof [and sometimes do, forming a 'column'] and stalactites hang on tight."
Rain water percolating through limestone, dissolves and absorbs the lime/calcium. Over many centuries, this lime solution drips from the roof of limestone potholes and caverns. There is a very slow build up of calcium that hangs down from the roof, eventually forming a stalactite. On the floor, the same depositing process forms an upright stalagmite. When they both meet a column stretching from the floor to the roof is formed.
== == A "stalactite" also known as dripstone, is like a stone icicle on the ceiling of a limestone cave. It develops when water, in which minerals (usually primarily calcium carbonate) is dissolved, drips though cracks in cave ceiling. As the water falls, it leaves behind microscopic amounts of the mineral. Over time, this collects to form an icicle-like structure. Note that a "stalagmite" is like an upside-down stalactite growing up from the floor. When water drips from a stalactite and hits the cave floor, there is often a microscopic mineral deposit left there as well. This deposit builds up over time. It is possible, by the way, for a stalactite and stalagmite to meet, forming a mineral column.
stalagmite. you can remember the difference between the ones hanging down, because they have to hold on tight, the ones from the ceiling of the cave are stalagtites, the ones on the floor of the cave are stalagmites. Thank some unsung park ranger for the ansewer to that one, told to us on a tour of a cave many years ago.
It all depends on the distance from the floor to the ceiling, the average growth rate is 0.13 mm a year

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.
