- Fluting (geology)
Fluting is a process of differential
weathering anderosion by which an exposed well-jointed coarse-grained rock such asgranite orgneiss , develops a corrugated surface of flutes; especially the formation of small-scale ridges and depressions by wave action.Fluting in glacial geology:
* the formation by glacial action of smooth deep gutterlike channels or furrows on the stoss side of a rocky hill obstructing the advance of aglacier ; the furrows are larger than glacial grooves, and they do not extend around the hill to the lee side. Also, a furrow so formed
*lineations or streamline grooves and ridges parallel to the direction of ice movement, formed in newly deposited till or older drift. They range in height from a few centimeters to 25 meters, and in length from a few meters to more than 20 km.Fluting with respect to
sedimentary action:
*the process of forming a flute by the cutting or scouring action of a current of water flowing over a muddy surface
*scalloped or rippled rock surfaces.
*flute cast
