Stalactites and stalagmites are formed fr0m deposition of calcium carbonate and other minerals, which is precipitated from mineralized water solutions.
Most caves are formed from limestone and dolostone sediment environments that are eroded by the corrosive water.
Stalactites and Stalagmites
§The average growth rate for a stalactite is 0.13 mm per year
Every stalactite begins with a single drop of mineral rich water. When the drop falls and evaporates it deposit a thin ring of (calcite). Each drop that forms and evaporates deposits another calcite ring layer.
If you were to drill a hole into Kaibab limestone, you would likely find either Toroweap Formation or ancient sandstone layers beneath it. The Toroweap Formation usually underlies the Kaibab limestone in the Grand Canyon region.
chemical change
The first hard layer is the Lockport Formation, which is made from limestone. The secound is softer, and is the Rochester Formation, and is made from shale and some very thin limestone bits. The third layer is underwater, and is Queenston Formation, which is made from shales and fine sandstone.
Limestone can and does appear in shades of green, due to impurities.
Limestone typically does not contain salt, as it is primarily composed of calcium carbonate. However, it is possible for limestone to contain trace amounts of salt if it has been in contact with seawater or other sources of sodium chloride during its formation.
Limestone.
Dissolving limestone.
A warm and humid climate would lead to rapid soil formation from limestone bedrock. The combination of warmth, moisture, and chemical weathering would accelerate the breakdown of the limestone and the formation of soil.

The metamorphism of limestone results in the formation of marble. Marble typically forms when limestone undergoes intense heat and pressure deep within the Earth, causing its minerals to recrystallize into a harder, denser rock with a distinct appearance.
Limestone can come in grey, yellow, white and a bunch of other colors too.
chemical change
The reaction of carbon dioxide in rainwater creates a weak carbonic acid, which dissolves limestone over time. This process, known as carbonation, leads to the formation of caves in limestone formations. Over thousands of years, the acidic water dissolves the limestone, creating underground tunnels and chambers.
