The Geology of Capricorn Caves
The Geology of Capricorn Caves. Cityville Apartments & Motel is the central Rockhampton base for visitors building a Rocky-and-Capricorn-Coast trip — 21-23 Bolsover Street, central CBD, two minutes' walk from the Fitzroy River and Quay Street's heritage dining strip, with self-contained apartments, motel rooms and townhouses suited to families, FIFO workers, corporate stays and weekenders alike.
The Capricorn Caves formed in the limestone of the Berserker Range through the dissolution process that mildly acidic rainwater produces when it percolates through the calcium carbonate rock over hundreds of thousands of years — the gradual enlargement of cracks and fissures into the chambers, the passages, and the formations that the cave system today contains. The stalactites hanging from the ceiling formed from the mineral-laden water dripping from above, each drop depositing a microscopic layer of calcite that accumulated centimetre by centimetre over millennia into the formations that the tour guide illuminates and explains. The stalagmites rising from the floor formed from the same drips — the splash depositing the mineral on the surface below the drip point, building upward at the same slow rate.
The flowstone formations — the sheets of deposited calcite that cover the walls and the floors where the water flowed rather than dripped — provide the formation variety that distinguishes the Capricorn Caves from simpler cave systems. The tree roots penetrating from the surface above demonstrate the geological-biological intersection that the cave's shallow depth beneath the surface enables. The Cathedral Cave's acoustic properties — the sound quality that concerts and ceremonies exploit — derive from the chamber's dimensions and the surface characteristics that the limestone formations produce. The geology is the content that transforms the cave visit from the visual spectacle into the intellectual experience — the understanding that every formation represents thousands of years of water chemistry working at the molecular scale to produce the structures that the human eye perceives as decorative but that geological time produced as inevitable.
