One of the mysteries of the English language finally explained.
The fracture and breaking up of rock by natural processes.
- ‘For example, cataclasis is a fracture-related process that changes a fault from a simple pair of moving surfaces to a zone containing deformed, poorly sorted, fractured, fine-grained material by converting country rock to fault rock.’
- ‘Close to the tectonic contact with the Mesozoic-Cenozoic cover there is a wide zone of cataclasis.’
- ‘Field-based and microstructural studies of the Zuccale fault reveal that an initial phase of pervasive cataclasis increased fault zone permeability, promoting influx of CO2-rich hydrous fluids.’
1950s: from cata- ‘completely’ + Greek klasis ‘breaking’.
