The addition of certain trace elements also disturbs the growth because they may influence the morphology of the growing crystals, known as fabric.. Their mechanism of formation/crystallization is also notably different from that of limestone stalagmites (CaCO3) but the common point is that it remains driven by gravity. Other minerals that may be deposited include other carbonates, opal, chalcedony, limonite, and some sulfides. For example, if tiny particles (known as colloids) are transported from the soil onto the stalagmite, this disturbs the stacking, and may create pores between growing crystals or even slightly change their shape.

Conditions that favour the deposition are: (1) a source rock above the cavern; (2) downward percolation of water supplied from rain; (3) tight but continuous passageways for this water, which determine a very slow drip; and (4) adequate air space in the void to allow either evaporation or the escape of carbon dioxide from the water, which thus loses some of its solvent ability. We were particularly interested to understand if there were common properties of laminated stalagmites. This is a mineral formation found in a cave. Corrections? Stalag mites.

Stalactites hanging from the ceilings of caverns commonly exhibit a central tube or the trace of a former tube whose diameter is that of a drop of water hanging by surface tension. This approximation to linearity can be used for geochronological applications, such improving the age-depth models necessary for attributing precise ages to geochemical proxies such as oxygen and carbon isotopes. At a global scale, we observe a strong, positive correlation between annual growth rate and mean annual temperature, and therefore also a negative correlation with latitude.
