Fluting (geology) - Wikipedia
In geomorphology, a flute is a narrow, shallow channel that runs nearly vertically down the face of a rock surface. It is formed by the weathering and erosion of the rock surface. Correspondingly, fluting is the erosional process by which flutes develop on the surface of well-jointed coarse-grained rock, such as granite or gneiss.
FLUTE CASTS - jsjgeology.net
Flute casts are scoop-shaped structures on the soles (undersides) of beds. They are features representing sediments that filled depressions on the immediately subjacent bedding plane. Flute casts form by erosive scour. The most common geologic phenomena that produce flute casts are turbidity currents (underwater sediment slides).
Fluting and Faceting of Rock Fragments | The Journal of Geology…
Rock surfaces are eroded by particle-laden currents of air and water so that under given conditions polishing, grooving, and fluting result. Polish is characteristic when the particles are fine and when abrasion predominates over solution in removal of material.
Flute (glacial) - Wikipedia
Glacial flutes, also known as glacial fluting, are low, narrow, elongate, straight, parallel ridges that range between several centimeters to a few meters both in width and height. This glacial landform generally consist of glacial till, but sometimes either sand or silt and clay.
Theoretical Analysis of the Formation of Glacial Flutes
In an analysis of the formation of flutes by subglacial cavities the flute-forming sediment is treated as a linear isotropic elastic material prior to failure, which occurs when Coulomb's law is satisfied.
The sculpting of formations….. “fluted” Vishnu Schist
Jul 15, 2011 · Fluting is a process of differential weathering and erosion by which an exposed well-jointed coarse-grained rock such as granite, gneiss or vishnu schist develops a corrugated surface of flutes; especially the formation of small-scale ridges and depressions by wave action.
Origin and inversion of fluting in granitic rocks - Taylor & Francis …
Nov 8, 2010 · Flutings are channels scored in steep slopes. They are found on granite bornhardts, blocks and boulders, and occur in a wide range of climatic conditions. Rivulets and seepages charged with chemicals and biota are capable of attacking and degrading granite, and this can occur below the surface, at the weathering front and on outcrops.
The Origin of Glacially Fluted Surfaces-Observations and Theory
Field relations of flutes are described and it is shown that a relationship exists between flute height and the height of the initiating obstruction. Subglacial observations indicate that flutes form when till is intruded into tunnels which tend to open up in the lee of obstacles.
Stream Fluting and Stream Erosion | The Journal of Geology: Vol …
Discontinuous grooves of irregular pattern result from turbulence of the water flow. In this article the grooves are termed "flutes," and the process of their formation is called "stream fluting." The importance of stream fluting in fluvial erosion is discussed.
An integrated process‐based model of flutes and tool marks in …
In utilizing the advances in fluid dynamics since Kuenen's pioneering research, this study demonstrates that it is possible to use flutes and tool marks to interpret flow type at the point of formation, the nature of flow transformations, and the mechanics of the basal layer.
