redeposition การใช้

• The use of ion sputtering must take into account the redeposition of sputtered material.
• They were presumably caused by the flood's scouring and redeposition of rocks and soil.
• However, other paleontologists believe that these interpretations are merely based on artifacts of erosion and redeposition in the early Paleogene.
• They are used in consumer household cleaning products to enhance performance, and prevent redeposition of the material removed from the dirty article.
• Other sources of problems for structures subjected to outer space are erosion and redeposition of the materials by sputtering caused by fast atoms and micrometeorites.
• The silica-cementation that creates a ganister typically results from dissolution of plant opal within a soil profile and its redeposition as silica cement within it.
• The location of the redeposition will not exactly coincide with the location of the sputtering, so one is still left with erosion rates that may be prohibitive.
• Reworked fossils are created by erosion exhuming ( freeing ) fossils from the rock formation in which they were originally deposited and their redeposition in an younger sedimentary deposit.
• However, a number of US phosphate deposits occur where the original marine-deposited phosphate minerals have been concentrated by weathering and redeposition, often under nonmarine conditions.
• If graphite is used, the gross erosion rates due to physical and chemical sputtering would be many meters per year, so one must rely on redeposition of the sputtered material.
• The Yilgarn Craton also has a considerable Tertiary and younger sedimentary veneer of palaeochannel deposits derived from prolonged erosion, sedimentation and redeposition of older cover sequences and regolith as well as the Archaean basement itself.
• They form from the redeposition of amorphous silica arising from the dissolution of siliceous spicules of sponges, or debris from radiolaria and the postdepositional replacement of either the enclosing limestone or chalk by this silica.
• Eight commercial contractors are currently licensed by the International Seabed Authority ( an intergovernmental organization established to organize and control all mineral-related activities in the international seabed area beyond the limits of benthic fauna over an area 5 10 times that size due to redeposition of suspended sediments.
• Without adding any redeposition theory, the Bimaran reliquary may therefore have been dedicated during the reign of Kharahostes ( 10 BCE  10 CE ), and probably at the beginning of his reign since the coins are not worn and where therefore basically new when they were introduced in the casket.
• It has been proposed that the aquifers could be recharged on geological time scales by a sequence of sublimation of the frozen seeps, atmospheric circulation of the vapor to the southern polar ice cap, redeposition of this onto the cap, basal melting under the ice mass, and groundwater circulation on a global scale.
• Haynes ( 1973 ) postulated that rock fracturing by tectonic stresses, weather, rock-on-rock percussion in streams and mudflows, pressure retouch of buried cobbles, and successive generations of flake removal and separation from cores through cycles of erosion and redeposition could have occurred during deposition of the alluvial deposits at Calico and produced specimens indistinguishable from artifacts.
• Krynine ( 1950 ) suggested that the red beds were primarily formed by the erosion and redeposition of red soils or older red beds, but a fundamental problem with this hypothesis is the relative scarcity of red-colored source sediments of suitable age close to an area of red bed sediments in diagenetic ) reddening of the sediment by the dehydration of brown or drab colored ferric hydroxides.
