PINNACLE SYNGENETIC KARST IN NAMBUNG NATIONAL PARK, WESTERN AUSTRALIA
Abstract:
Simultaneous karstifcation and lithifcation of aeolian calcarenite in the southwest coastal part of Western Australia produced syngenetic karstic geomorphological features, such as solution pipes, maze caves, collapsed dolines and pinnacles. $e formation of these geomorphological features was greatly inluenced by the poor cementation and matrix porosity of the calcarenite. Pinnacles, calcarenite pillars up to 5 metres tall with one or more peaks and various types of sediment layers, are most numerous and densest in an area called the Pinnacles in Nambung National Park, Western Australia. Their detailed characteristics and origin are still partially unknown and controversial. Theories suggest that the pinnacles are the final product of one or more of corrosive expansion and coalescence of solution pipes, cemented sediment surrounding the roots, cemented fill of solution pipes, products of focused cementation or remainders of tree-trunks. This article presents descriptions of pinnacles in Nambung National Park based on my feldwork and suggests a polygenetic origin for the pinnacles, with roots playing a major role. The genesis of pinnacles is far more complex than the theories presented so far.
