In order to figure out how the pointed pinnacles in the stone forests are formed, the team looked at karst topography, which is the result of the erosion of soluble rocks like limestone. Limestone covers approximately 10% of Earth and is incredibly porous. It easily decays when exposed to acidity, and rainwater is a big culprit in this phenomenon.

Karst Topography and Sinkholes. Limestone, with its high calcium carbonate content, is easily dissolved in the acids produced by organic materials. About 10% of the earth's land (and 15% of the United States') surface consists of soluble limestone, which can be easily dissolved by the weak solution of carbonic acid found in underground water.

How does weathering affect limestone? - Internet Geography

Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
