"Carboniferous" Quotes from Famous Books
... of common food admit of being placed, as below, in a Table, by which we see at a glance how much nutriment of class C, and how much of class N, is found in 100 parts, gross weight of any of them. Thus, by a simple computation, the effective value of a dietary may be ascertained. Class C, are the carboniferous principles, that maintain respiration; Class N, are the nitrogenous principles, that repair waste of tissue. N will partly replace C, but at a great waste: ... — The Art of Travel - Shifts and Contrivances Available in Wild Countries • Francis Galton
... consumed in the building of this great Canyon. In that time ten thousand feet of non-conformable strata have been deposited, elevated, tilted, and washed away; the depression of the Canyon Surface serving for the depositing of Devonian, Lower Carboniferous, Upper Carboniferous, Permian, Triassic, Jurassic, Cretaceous; the formation of the vast eocene lake and its total disappearance; the opening of the earth's crust and the venting from its angry stomach the foul lavas—-the mind reels and ... — The Pony Rider Boys in the Grand Canyon - The Mystery of Bright Angel Gulch • Frank Gee Patchin
... consist principally of calcium phosphate and calcium carbonate in varying proportions. Depending on the amount of secondary enrichment, they form two main types of deposits. The extensive beds of the western United States (in the upper Carboniferous) are hard, and very little enrichment by weathering has taken place; they carry in their richer portions 70 to 80 per cent calcium phosphate, and large sections range only from about 30 to 50 per cent. In the southeastern deposits (Silurian and Devonian in Tennessee ... — The Economic Aspect of Geology • C. K. Leith
... is so cold," I replied briefly, and got what I wished with a grunt of "Dat's so, honey!" Negroes are constitutionally averse to winter and cold, and recognize, without knowing why, the carboniferous properties of pork and pone. I bore my treasures off to the dining room, shut the door, and began my experiment in the hottest ... — When Grandmamma Was New - The Story of a Virginia Childhood • Marion Harland
... mineralogy and asked him where he thought those diamonds came from. The professor secured the map of the geologic formations of our continent, and traced it. He said it went either through the underlying carboniferous strata adapted for such production, westward through Ohio and the Mississippi, or in more probability came eastward through Virginia and up the shore of the Atlantic Ocean. It is a fact that the diamonds were there, for they have been ... — Acres of Diamonds • Russell H. Conwell
... disprove this. For example, the fossil plants found in our Lower Cretaceous rocks in Central North America indicate a temperate climate in latitude 35 to 40 in the Cretaceous age. The coal-flora, too, and the beds of coal, indicate a moist, equable, and warm but not hot climate in the Carboniferous age, millions of years before the Tertiary, and three thousand miles farther south than localities where magnolias, tulip-trees, and deciduous cypresses, grew in the latter age. Some learned and cautious geologists even assert that there have been several ... — Ragnarok: The Age of Fire and Gravel • Ignatius Donnelly
... an area of thin population devoted to horse and cattle raising in close proximity to the teeming urban life of Paris. The eastern lowland of England also can be differentiated economically and historically chiefly according to differences of underlying rocks, Carboniferous, Triassic, Jurassic, chalk, boulder clays, and alluvium, which also coincide often with slight variations of relief.[1045] In Russia the contrast between the glaciated surface of the north and the Black Mould ... — Influences of Geographic Environment - On the Basis of Ratzel's System of Anthropo-Geography • Ellen Churchill Semple
... on the mere absence of their remains from the secondary strata, nevertheless that absence is noteworthy, seeing that existing fish families, e.g. sharks (Squalidae), have been found abundantly even down so far as the carboniferous rocks, and traces of them in the ... — On the Genesis of Species • St. George Mivart
... Structure.—The fundamental rocks of this region belong to the Silurian, Devonian, and Carboniferous systems, consisting of schists, grits, and limestones, with occasional horizontal beds of Miocene sandstone and shale with lignite, resting on the upturned edges of the older rocks. Scattered over ... — Volcanoes: Past and Present • Edward Hull
... the maddest geologist under such circumstances would have studied the nature of the rocks that we were passing. I am sure I did trouble my head about them. Pliocene, miocene, eocene, cretaceous, jurassic, triassic, permian, carboniferous, devonian, silurian, or primitive was all one to me. But the Professor, no doubt, was pursuing his observations or taking notes, for in one of our halts he said ... — A Journey to the Interior of the Earth • Jules Verne
... probably rests on sedimentary strata. For on the western side of Irkaipij the plutonic rock is seen to rest on a black slate with traces of fossils, for the most part obscure vegetable impressions, probably belonging to the Permian Carboniferous formation. ... — The Voyage of the Vega round Asia and Europe, Volume I and Volume II • A.E. Nordenskieold
... several cases distinct from those of India. We know as yet too little of the geology of the eastern peninsula to say from what epoch dates its connexion with Indo-Oceanic land. Mr. Theobald has ascertained the existence of Triassic, Cretaceous, and Nummulitic rocks in the Arabian coast range; and Carboniferous limestone is known to occur from Moulmein southward, while the range east of the Irrawadi is formed of younger Tertiary rocks. From this it would appear that a considerable part of the Malay peninsula must have been occupied by the sea ... — The Story of Atlantis and the Lost Lemuria • W. Scott-Elliot
... the decomposition of plants can cause organic matter to assume these different states, other scientists think that it is not necessary for such matter to have been peat and lignite in order to become coal, and that at the carboniferous epoch plants were capable of passing directly to the state of coal if the conditions were favorable; and, in the same way, in the secondary and tertiary epochs the alteration of vegetable tissues generally led to lignite, while now they give rise to peat. In other words, the ... — Scientific American Supplement, No. 481, March 21, 1885 • Various
... there to question the continued supply of either coal or ore. The life of the coal mines which the Tata Company possess within one hundred miles of their works is estimated at two hundred years, and they form only a very small portion of the great carboniferous area known as the Gondwana measures. They produce the best coking coal in India, and though much inferior as such to most British coal mines, against this disadvantage can be set off the much greater richness of the iron ... — India, Old and New • Sir Valentine Chirol
... the same age with the slates and grits of Carnarvon and Merioneth. Again, slaty cleavage having been first found only in the lowest rocks, was taken as an indication of the highest antiquity: whence resulted serious mistakes; for this mineral characteristic is now known to occur in the Carboniferous system. Once more, certain red conglomerates and grits on the north-west coast of Scotland, long supposed from their lithological aspect to belong to the Old Red Sandstone, are now identified with the Lower Silurians. These are a few instances ... — Essays: Scientific, Political, & Speculative, Vol. I • Herbert Spencer |
