The Economic Aspect of Geology The uplift.—After sedimentation had proceeded to some such extent as indicated, the sea again retired from central Wisconsin. The Geography of the Region about Devils Lake and the Dalles of the Wisconsin 2011-11-29T03:00:17.347Z When it is necessary to observe sedimentation reactions in very small quantities of fluid, these tubes will be found much more convenient than the 5 by 0.5 cm. test-tubes previously mentioned. The Elements of Bacteriological Technique A Laboratory Guide for Medical, Dental, and Technical Students. Second Edition Rewritten and Enlarged. The sedimentation process, moreover, raises river channels above the level of the nearby terrain.

Mechanical sedimentation and filtration greatly improve waters of this class, but do not necessarily render them entirely pure. Human Foods and Their Nutritive Value The sedimentation tank was of sufficient size, when compared with the area of the experimental slow sand filter, to represent the Georgetown and McMillan Park Reservoirs when used in connection with the large filters. Transactions of the American Society of Civil Engineers, vol. LXXII, June, 1911 Water Purification Plant, Washington, D. C. Results of Operation. For instance, an igneous rock may become a schist without going through the intermediate stage of sedimentation. The Economic Aspect of Geology The massive eatings of powered blades and scoops to get at coal and other minerals on the steep slopes of the North Branch watershed and elsewhere, add heavily to sedimentation. The Nation's River A report on the Potomac from the U.S. Department of the Interior By sedimentation, and filtration through canvas, cinders and sand, the water is clarified and turned into the creeks again clean. On the Fringe of the Great Fight There are a considerable number of chemical substances that may be added to water in order to purify it by carrying down the suspended matter as well as bacteria, by sedimentation. Human Foods and Their Nutritive Value In Mr. Hazen's paper on "Sedimentation"1 there is an interesting development of the theory of the removal of suspended matter by sedimentation in the pores of a layer of sand. Transactions of the American Society of Civil Engineers, vol. LXXII, June, 1911 Water Purification Plant, Washington, D. C. Results of Operation. Our least satisfactory knowledge of the Lake Superior ores relates to the peculiar conditions which determined the initial stage of sedimentation of the so-called iron formation. The Economic Aspect of Geology They have already had important local effects in the Potomac States as throughout the country, but for maximum value in relieving sedimentation they are going to need much wider and more intensive application. The Nation's River A report on the Potomac from the U.S. Department of the Interior On the floors of the seas and oceans we have not only the region where the greater part of the sedimentation is effected, but that in which the work assumes the greatest variety. Outlines of the Earth's History A Popular Study in Physiography Explain the processes employed for the removal of mechanical impurities of water by sedimentation and the use of chemicals. Human Foods and Their Nutritive Value In two cases, the preliminary treatment was rapid filtration, while the third consisted of sedimentation and coagulation. Transactions of the American Society of Civil Engineers, vol. LXXII, June, 1911 Water Purification Plant, Washington, D. C. Results of Operation. As in the case of the Clinton iron ores, no present-day sedimentation gives an adequate clue. The Economic Aspect of Geology These recommendations represent the culmination of intensive studies in the areas of water supply and flood control, water quality, sedimentation and erosion, and landscape and recreation. The Nation's River A report on the Potomac from the U.S. Department of the Interior These great events are of a rhythmic character; the crust, as it were, pulsating under the combined influences of sedimentation and denudation. The Birth-Time of the World and Other Scientific Essays Drinking water may be purified by aëration, or by straining, boiling and subsequent sedimentation and removal of the sediment by filtration through fresh and clean sand. Gilbertus Anglicus Medicine of the Thirteenth Century Discontinued; sand filter being used for sedimentation experiments. Transactions of the American Society of Civil Engineers, vol. LXXII, June, 1911 Water Purification Plant, Washington, D. C. Results of Operation. Coal deposits are direct results of sedimentation of organic material. The Economic Aspect of Geology For the control of sedimentation and erosion and their effects, the following action will be needed: a. The Nation's River A report on the Potomac from the U.S. Department of the Interior The mountain range can only arise where the geosyncline is deeply filled by long ages of sedimentation. The Birth-Time of the World and Other Scientific Essays Graded by this and that species, the debris is reduced to fine particles, which upon sedimentation help to raise the level of the reef and thus prepare foundations for dry land. My Tropic Isle Whether any of this gain in volume is lost in the process of sedimentation and reconsolidation, I do not know. Time and Change To do this, however, the conditions of sedimentation, the initial irregularities of the beds, the structural conditions, including unconformities, and other factors must be studied. The Economic Aspect of Geology Was this region land or sea, an area of erosion or sedimentation, during the Jurassic period? The Elements of Geology For long ages and through a succession of geological epochs, sedimentation had proceeded so that the accumulations of Palaeozoic and Mesozoic times had collected in the geosyncline formed by their own ever increasing weight. The Birth-Time of the World and Other Scientific Essays In a third class of sedimentary ores, the iron minerals are supposed to have been introduced as replacements of limestones subsequent to sedimentation. The Economic Aspect of Geology In general, the geologic processes entering into the formation of abrasives cover almost the full range from primary igneous processes to surface alterations and sedimentation. The Economic Aspect of Geology In the selection of key horizons, knowledge of the conditions of sedimentation is very important. The Economic Aspect of Geology Both by sedimentation and by subsidence the trough had now become a belt of weakness in the crust of the earth. The Elements of Geology It closes with a reference to the fascinating problems presented by the inner nature of sedimentation: a branch of science to which I endeavoured to contribute some years ago. The Birth-Time of the World and Other Scientific Essays Iron ores are represented in nearly all phases of the metamorphic cycle, but the principal commercial values have been produced by processes of weathering and sedimentation at and near the surface. The Economic Aspect of Geology Problems of wave action, shore currents, shifting of shores, erosion, and sedimentation, which are of great importance in such operations, have long occupied the attention of the geologist. The Economic Aspect of Geology Such ores are not always easy to discriminate from ores resulting primarily from sedimentation. The Economic Aspect of Geology The lands must be uplifted before they can be eroded, and since they must be eroded before their waste can be deposited, movements of elevation are a prerequisite condition for sedimentation also.
