Corrasion

Owsley was able to determine the body's position relative to the river by patterns of "corrasion" - wear by water-bourne sediment - on the bone. ❋ Unknown (2006)

Abrasion: (this is also known as corrasion) - this is where rock fragments are hurled at cliffs by breaking waves, gradually scraping away at the cliff face; the load acts as a grinding tool. ❋ Kparkins (2010)

Bones on the left side of the body showed consistent patterns of corrasion, more than on the right side, indicating that this was the side of the body that eroded out of the bank first. ❋ Unknown (2006)

Nowhere else on the face of the globe is one so vividly impressed by the vastness of the work of corrasion as in the northwestern part of ❋ Jewett Castello Gilson (N/A)

It seems possible that there may have been in this region some great lake which lifted the waters up to the top of the ridge to begin their work of corrasion. ❋ Frederick Samuel Dellenbaugh (1894)

It is also clear that if, by some chance, the precipitation of the high sources should increase, the corrasion of the stream-beds in the canyons would likewise increase and outrun with still greater ease the erosion of their immediate surroundings. ❋ Frederick Samuel Dellenbaugh (1894)

Admitting that the sharper declivity of the Kanab would enhance its power of corrasion, nevertheless we should expect to see it approach the Grand Canyon by leaps and bounds, like the ❋ Frederick Samuel Dellenbaugh (1894)

* In connection with the subject of erosion and corrasion the reader is advised to study the following works, which are the standards: The ❋ Frederick Samuel Dellenbaugh (1894)

This backward drainage leaves the immediate brink, or "rim," till the last, in its work of erosion and corrasion, and the rim consequently is left higher than the region away from it. ❋ Frederick Samuel Dellenbaugh (1894)

It is a singular fact that some side canyons, the Kanab, for example, while now possessing no running water, or at best a puny rivulet, and depending for their corrasion on intermittent floods, meet on equal terms the great Colorado, the giant that never for a second ceases its ferocious attack. ❋ Frederick Samuel Dellenbaugh (1894)

Havasupai farther down, but, on the contrary, there are parts that appear to be at a standstill in corrasion, or even filling up, and its floor is a regular descent, except for the last three or four miles where the canyon is clogged by huge rocks that seem to have fallen from above. ❋ Frederick Samuel Dellenbaugh (1894)

Where rocks take a polish, as in Marble Canyon, the scouring and polishing work of corrasion is seen in the shining bright surface as far as the water rises. ❋ Frederick Samuel Dellenbaugh (1894)

The powers of erosion are far slower than those of corrasion, especially in an arid region, because they are intermittent. ❋ Frederick Samuel Dellenbaugh (1894)

These broad canyons, or canyon valleys, are carved by the streams in obedience to an interesting law of corrasion. ❋ John Wesley Powell (1868)

A suspicion arises, on contemplating some of these apparent discrepancies, that the prevailing conditions of corrasion are not what they were at some earlier period, when they were such that it was rendered more rapid and violent; that there was perhaps an epoch when these deep-cut tributary canyons carried perennial streams, and when the volume of the Colorado itself was many times greater, possessing a multiplied corrasive power, while the adjacent areas were about as arid as now. ❋ Frederick Samuel Dellenbaugh (1894)
