Lithological control of solution flute form: a comparative study

Morphometric data are presented on 300 solution flute sets developed at 21 sites worldwide on the three main groups of soluble rocks, namely limestone , gypsum and salt. Lithological control is shown to create significant diff erences in flute form between the rock groups, and also within individual r ock groups and local sites. Climatic control of flute form is shown by prev iously published data. The means by which these controls are exerted is as yet unclear. Further research relating detailed rock properties to flute fo rm is required in order to elucidate such controls.
