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 ...

The most common process by which limestone caves form involves carbonic acid — or weakly acidic groundwater — as the primary agent. When carbonic acid contacts limestone, it dissolves minerals ...

As climate change gathers pace, the record preserved in the Pinnacles’ iron nodules and limestone pillars becomes increasingly important.
