denudations

The gigantic phenomena and wonderful agencies of that marvellous period in geological history -- its vast icefields and glaciers, with their movements, drifts, and denudations -- its coast ice and glacial lakes and rivers -- the risings and sinkings of level of islands and continents, are all considered and discussed in a thoroughly intelligent and scholarly manner.

It is reversing the natural order of things to give results without the investigations which have led to them; and I should not have introduced the subject here except to show that the fresh-water denudations and the oceanic encroachments which have formed the

These mighty changes have gradually been accomplished, and the accumulated denudations of the mineral zones have defended themselves by strata of crystallized silicates of quartz of various thicknesses, and thus in places beneath such system of defense, or by their own concretion, have preserved in many localities a thickness of from 500 to 600 feet of conglomerate, but without this necessary cementation its further removal is very certain when again attacked by water.

The denudations that left our stark Cornish coasts as we know them now for the most part occurred in times that are dim and legendary.

These denudations of the sea no doubt began as soon as the breaking up of the ice exposed the drift to its invasion; in other words, at a time when colossal glaciers still poured forth their load of ice into the Atlantic, and fleets of icebergs, far larger and more numerous than those now floated off from the Arctic seas, were launched from the northeastern shore of the United States.

During the last four or five years I have been engaged in a series of investigations, in the United States, upon the subject of the denudations connected with the close of the glacial period there, and the encroachments of the ocean upon the drift deposits along the

These denudations and subsequent depositions have been caused by alternations of temperature and combined action of air, water, and time since the creation of the world; and powerful demonstrations of these transformations instruct us in all directions, if we care to observe them.

The thickness of the deposits gives a measure for the colossal scale of the denudations by which this immense accumulation was reduced to its present level.

Amazonian formation to the Rio drift, [C] of the glacial origin of which there cannot, in my opinion, be any doubt; thirdly, on the fact that this fresh-water basin must have been closed against the sea by some powerful barrier, the removal of which would naturally give an outlet to the waters, and cause the extraordinary denudations, the evidences of which meet us everywhere throughout the valley.

Nowhere have we such good opportunities as in our coal mines of observing the upraisals, the downfalls, the dislocations, contortions, and denudations which rocks have suffered.
