"Sedimentary" Quotes from Famous Books
 ... mathematically certain that, in any given vertical linear section of an undisturbed series of sedimentary deposits, the bed which lies lowest is the oldest. In many other vertical linear sections of the same series, of course corresponding beds will ...

... assume a solid form. It is by no means certain what is the true primary rock—for a long time it was almost universally assumed to be granite, since granite is uniformly found underlying the oldest sedimentary rocks that are known. But as these rocks have been forced from their original position and tilted up, the underlying stratum may probably be of later date than the upper ones, since it was the elevating agent. So that we can have no certain ...

... not of all, of the dry land of the globe. But the continuity of terrestrial life since the Devonian and Carboniferous periods, and the existence of very similar forms in the corresponding deposits of every continent—as well as the occurrence of sedimentary rocks, indicating the proximity of land at the time of their deposit, over a large portion of the surface of all the continents, and in every geological period—assure us that no such disappearance ...

... frequent, or than females of any age, in whom the prostate is absent, and the urethra simple, short, readily dilatable, and seldom or never strictured. When an obstruction exists, lithic concretions take place in the urinary apparatus in the same manner as sedimentary particles cohere or crystallize elsewhere. The urine becoming pent up and stagnant while charged with saline matter, either deposits this around a nucleus introduced into it, or as a surplus when the menstruum is insufficient to suspend it. The most depending part of the bladder is that where lithic ...

... of potatoes are shipped yearly, are yellow sand. This potato district is confined to ridges running parallel with Lake Erie, which, according to geological indications, have each at different periods defined its boundaries. This sand owes much of its potato-growing qualities to the sedimentary deposit of the lake and to manural properties furnished by the decomposition of the shells of water-snails, shell-fish, ...

... and does occur in sedimentary rocks of varied character, but, so far as my observation has extended, never in quantity in sandstone. In the Lower Silurian rocks anthracite occurs, both in the Old World and in the New, where no metamorphism has affected it, and where it is simply the normal result of the ...

... activity is limited to commercial fishing. The proximity to nearby oil- and gas-producing sedimentary basins suggests the potential for oil and gas deposits, but the region is largely unexplored, and there are no reliable estimates of potential reserves; commercial exploitation ...

... reached from India to South America. Science has gone so far as 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, ...

... occurring in the Catoctin Belt is the sedimentary series. It is all included in the Cambrian period and consists of limestone, shale, sandstone and conglomerate. The two border zones of the Catoctin Belt, however, contain also rocks of the Silurian and Juratrias periods. In general, the sediments are sandy and calcareous in the ...

... 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 correspondence ...

... 1. Sedimentary strata have been carried down, by movements of the earth's crust, far below the surface, covered by other deposits, and subjected to great heat, which, aided by the water contained in the rocks and various chemical reactions, has effected a re-arrangement of the mineral ...

... which accounts have been handed down by their fathers, and at the time of which deep fissures appeared that have subsequently extended. Major MacMahon adds that this crack marks the line of a gigantic geological fault, with sedimentary rocks to the east of it and igneous rocks to the west, and he believes, rightly, I think, that the length of this fault line exceeds that of any other ...

... the northwest until, after a course of about 1300 miles, it reaches the south coast of the Aral Sea. In parts the stream has a breadth of 800 yards, with a depth of 20 feet, and a very rapid current; but the vast quantity of sedimentary matter which it brings down to the month, forming shifting sands and banks, renders it difficult to navigate. A great portion of the volume of the stream is absorbed in the irrigation of the Khivan Oasis. The tendency ...
