"Sedimentary" Quotes from Famous Books
 ... soil in that region was interesting enough. Under a greyish white surface layer there were thin sedimentary strata of pebbles, deposited evidently by water, then under these a thick stratum—30 ft. or more—of warm-coloured red earth. The streams which had cut their way through this geological formation were invariably ...

... to even give it a name; it is called "Lemuria," and here, it is claimed, the human race originated. An examination of the geological formation of our Atlantic States proves beyond a doubt, from the manner in which the sedimentary rocks, the sand, gravel, and mud—aggregating a thickness of 45,000 feet—are deposited, that they came from the north and east. "They represent the detritus of pre-existing lands, the washings of rain, rivers, coast-currents, and other agencies of erosion; and since the areas supplying ...

... than the lowest part visible in the channel of the river. The parallel course of small tributaries joining rivers, which seem to be the middle drain of extensive plains, may have been marked out during the deposition of the sedimentary matter as tributaries, on entering the channel of greater streams, immediately become a portion of them; hence it is, the general inclination being common to both, that such tributaries do not cross these sediments of floods now termed plains in order to join the main channel ...

Let the {284} observer remember Lyell's profound remark that the thickness and extent of sedimentary formations are the result and measure of the degradation which the earth's crust has elsewhere suffered. And what an amount of degradation is implied by the sedimentary deposits of many countries! Professor ...

... of so many different kinds that form the crust of our globe, there is a class which has been called sedimentary (terrains de sediment). Those formations to which this name is properly applied, are composed wholly, or in part, of detritus, carried by water like the mud of our rivers, or the sands of the beaches of the sea. These sands, in a state of ...

... of the climb up to the rim I had to attend to the business of riding and walking. The trail was rough, steep, and long. Once Haught called my attention to a flat stone with a plain trail made by a turtle in ages past when that sandstone was wet, sedimentary deposit. By and bye we reached the last slopes up to the mesa, green, with yellow crags and cliffs, and here and there blazing maples to remind me again that ...

... after that great current enters, for some distance the two run side by side in the same channel, and yet are divided by a very distinct line of demarcation. It is only after the frequent sinuosities of the channel, that the two waters are thrown into each other and fairly blend. The sedimentary condition of the Missouri is so great that drift floating upon its muddy surface, by accretion becomes so heavily laden with earthy matter that it sinks to the bottom. This precipitation of drift ...

... North Platte brings a considerable amount of earthy sediment from the heart of that Alpine region. After fairly entering upon the Plains, every stream begins to burrow and to wash, growing more and more turbid, until it is lost in 'Big Muddy,' the most opaque and sedimentary of all great rivers. I suspect that all the other rivers of this continent convey in the aggregate less earthy matter to the ocean than the Missouri pours into the previously transparent Mississippi, thenceforth an unfailing testimony that ...

... of nitrogen salts, such as the nitrate-fields of Chili and the saltpetre soils of India, &c., also only occur superficially. Notwithstanding these facts, however, the amount of nitrogen which exists at probably considerable depths from the surface must be very great. There are few sedimentary rocks which do not contain it. At Rothamsted a sample of calcareous clay, taken from a depth of 500 feet, contained .04 per cent—that is, as much as is found, on an average, ...

Other conditions being the same, houses built on alluvial ground suffered most of all; and the destruction was also great in those standing on soft sedimentary rocks such as clays and friable limestones. On the other hand, when compact limestones or ancient schists formed the foundation-rock, the amount of damage was conspicuously ...

... is a rock which is formed under immense pressure and in the presence of confined moisture, needing a weight of fifteen thousand pounds upon every inch. Therefore, wherever granite is found we know that it has not been formed by deposit, like limestone and sandstone and slate and other sedimentary rocks, but at a prodigious depth under the solid ground, and by slow crystallizing of molten substances. There must have been from two to five miles of other rock lying upon the stuff that crystallized into granite. A wrinkling in the skin of the earth exposed the granite, a wrinkling ...

... said so. Even to his relatively untrained eye, this was a place where a volcanic fissure had opened ages ago, allowing igneous rock to thrust sharply upward through the sedimentary layers of the older ground. Now the formation had weathered until it was like a barren hill built on top of a fertile one. On the steep slope of igneous rock no grass had managed to get hold, although a few hardy ...

... that this heterogeneity has been vastly increased by the action of the Earth's still molten nucleus upon its envelope, whence have resulted not only a great variety of igneous rocks, but the tilting up of sedimentary strata at all angles, the formation of faults and metallic veins, the production of endless dislocations and irregularities. Yet again, geologists teach us that the Earth's surface has been growing more varied ...

It contains 22,000 miles of surface, with a depth of 900 feet in the deeper parts, though near the shore it grows gradually shoal. The rocks which compose its rim are of a sedimentary nature, and afford few indentations for harbors. The shores are low, and lined in many places with immense sand-banks. Green Bay, or Bale des Puans of the Jesuits, on the west coast, is 100 miles long and 20 broad. Great and Little Traverse Bays occur on the eastern coast, and Great ...

... are INVARIABLY IN THE HIGHEST REGIONS and at a long distance from their mouths, so that the flood waters have many miles of opportunity to run a race with the comparatively feeble erosive forces of desert lands. The main stream-courses are thus in the lower arid regions and in sedimentary formations, while their water-supply comes from far away. The deepest gorges, therefore, will be found where the rainfall is least, unless diminishing altitude interferes. Thus the greatest gorge of the whole basin, the Grand Canyon, is the one farthest from the ...

... result was the demonstration that many groups of animals existed in earlier ages that seem to have no descendants of the same nature to-day, and also that many or most of our modern groups are not represented in the earliest formed sedimentary rocks, although these recent forms possess hard parts which would surely be present somewhere in these levels if the animals actually existed in those times. But the meaning of these facts escaped Cuvier's mind. He was a believer in special creation, like Linnaeus and all ...

... water. Hence, we see that the materials of the interior of the earth must be either metallic or very compressible. To assign a metallic nucleus to the earth, is repugnant to analogy; and it is not rendered even probable by facts, as we find volcanic emissions to contain no heavier elements than the sedimentary layers. Besides, there are indications of a gradual increase of density downwards, such as would arise from the compressibility of the layers. Seeing, therefore, the equilibrium of the whole mass, ...

The whole fabric of palaeontology is based upon two propositions: the first is, that fossils are the remains of animals and plants; and the second is, that the stratified rocks in which they are found are sedimentary deposits; and each of these propositions is founded upon the same axiom, that like effects imply like causes. If there is any cause competent to produce a fossil stem, or shell, or bone, except a living being, then palaeontology ...

In this part, however, a very large proportion of the rock (and in some cases nearly all of it) would be formed of sedimentary matter, either in an excessively fine, or in a moderately coarse state, and with the particles almost blended together. The conglomerate which was formed of rounded pieces of the branched corals, on the shores of the lagoon, would differ from that formed on the islets and derived from the outer ...

Considerations as to the origin and spread of languages also seem to require a much greater antiquity for the human race than has been popularly allowed; and geologists have always claimed myriads of years as required for the sedimentary formations of the globe.

It is evidently the bed of some ancient stream, because it is walled in by steep banks of hard bed-rock, precisely like the banks of rivers and ravines in which water now runs, and because it is composed of clay which is evidently a sedimentary deposit, and of pebbles of black and white quartz, which could only be rounded and polished as they are by the long continued action of swiftly running water.
