However, hydrothermal conditions do not seem to control the presence of folia: the temperature of water and the temperature of calcite crystallization deduced from fluid inclusions range across a large spectrum (from 20 to 120 °C), and Hurricane Crawl is a cold epigenic cave. Two main hypotheses have been proposed for the origin of folia:
