"Sedimentary" Quotes from Famous Books
 ... of the rise and progress of palaeontology. 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, ...

... indigo vat should be thoroughly freed from any soap which may have been used in the boiling out. Then, after dyeing, they ought to be well rinsed in water and passed through a sour made with sulphuric acid (2 lb. in 10 gallons), and then washed again. Vats highly charged with sedimentary matter, or with zinc or lime, are often the cause of loose shades. The remedy is obvious, viz., the discarding of such vats and the preparation of new ones, in fact old vats are perhaps more fruitful sources of loose shades than any other cause. Soft ...

... the question of the soil. The Tokay Eperies group of hills is one of several well-defined groups of volcanic rocks that exist in Hungary and Transylvania. In the Tokay district the formations are partly eruptive, partly sedimentary, but nowhere older than the Tertiary period, say the geologists. The Hegyalia (which means "mountain-slopes" in the Magyar tongue) forms the southern spur of the extended volcanic region, composed of trachyte and rhyolithe, ...

... enforced his pleas; and in the subsequent years thousands of students, many of them of the highest families, quietly left their homes, donned the peasants' garb, smirched their faces, tarred their hands, and went into the villages or the factories in the hope of stirring up the thick sedimentary deposit of the Russian system[227]. In many cases their utmost efforts ended in failure, the tragi-comedy of which is finely set forth in Turgenieff's Virgin Soil. Still more frequently their goal proved to be—Siberia. But these young men and women did ...

... to the exclusion of another. Man observes the annual decomposition of crystalline and igneous rocks, and may sometimes see their conversion into stratified deposits; but he cannot witness the reconversion of the sedimentary into the crystalline by subterranean heat. He is in the habit of regarding all the sedimentary rocks as more recent than the unstratified, for the same reason that we may suppose him to fall into the opposite error if he saw the origin of the ...

... Piave there stretches, at a variable distance of from three to five miles from the actual shore, a bank of sand, divided into long islands by narrow channels of sea. The space between this bank and the true shore consists of the sedimentary deposits from these and other rivers, a great plain of calcareous mud, covered, in the neighbourhood of Venice, by the sea at high water, to the depth in most places of a foot or a foot and a half, and nearly everywhere exposed at low tide, but divided by an intricate network of narrow ...

... 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, and the consequent hydrostatic balance of the land in the sea,—seeing ...

Every successive stratum of sedimentary rock, sand, or gravel, is a proof that changes of level have taken place; and the different species of animals and plants, whose remains are found in these deposits, prove that corresponding changes did occur ...

The core is formed by the mountain masses of Rhodope, Belasitza, Perin and Rila; and here Palaeozoic and Mesozoic beds are absent, and the earliest sedimentary deposits belong to the Tertiary period and lie flat upon the crystalline rocks. Upon the margins, however, Cretaceous beds are found. The eastern parts of Greece are composed almost entirely of Cretaceous beds, but nevertheless they must be considered to belong ...

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.

The ridge here rises abruptly to the height of about 4,000 feet, its face being very prominently marked with a massive stratum of rose-colored granular quartz, which is evidently an altered sedimentary rock, the lines of deposition being very distinct. It is rocky and steep—divided into several mountains—and the rain in the valley appears to be always snow on their summits at this season. Near ...

The second portion of the work deals exclusively with Historical Palaeontology, each formation being considered separately, as regards its lithological ...

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 ...

... lower members of a series of sedimentary rocks are certainly older than the upper; and when the notion of age was once introduced as the equivalent of succession, it was no wonder that correspondence in succession came to be looked upon as a correspondence in age, or "contemporaneity."

The quartz is not found, as might naturally be supposed from its position among sedimentary rocks, lying in anything like a plain, even sheet of equal thickness. On the contrary, it is seen to be marked by folds or plications, occurring at tolerably regular intervals, and crossing the vein at an angle of 40 deg. or 45 deg. to the west. Similar folds may be produced in a sheet ...

Investigations show that the Earth has been continually becoming more heterogeneous in virtue of the multiplication of sedimentary strata which form its crust; also, that it has been becoming more heterogeneous in respect of the composition of these strata, the later of which, being made from the detritus of the earlier, are many of them rendered highly complex by the ...

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 less than in ...

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.

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.

For these remains, still in evidence on the spot, consist of a few small marine deposits of Upper Miocene age; and I recollect distinctly that after the main group had been for some time raised above the surface of the ocean, and after sand and streams had formed a small sedimentary deposit containing Upper Miocene fossils beneath the shoal water surrounding the main group, a slight change of level occurred, during which this minor island was pushed up with the Miocene deposits on its shoulders, as a sort of natural memorandum to assist my random scientific recollections. ...

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 ...

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 ...
