glaci- (glacio-) Dominated by glacial ice. The prefix is followed by a term indicating the environment or process that is so dominated, e.g. glaciaquatic (of water derived from a glacier), glacioeustasy (the theory that changes in sea level result from the growth and decay of ice sheets), glacifluvial (of sediments or land-forms produced by meltwater streams escaping from a glacier), glacioisostasy (the theory that local flexing of the Earth's crust occurs as a result of the loading and unloading that takes place as large ice sheets wax and wane), glacilacustrine (pertaining to a lake adjacent to a glacier), and glaciomarine (of sediments laid down in a sea environment near a glacier). See also GLACIOTECTONICS.
