phosphatic การใช้

• These microfossils are made of hydroxylapatite ( a phosphatic mineral ).
• PROM is known as a green chemistry phosphatic fertilizer.
• Phosphatic particles, laminae and beds are considered condensed when they have been concentrated.
• This is helped by the extracting and reworking processes of phosphatic particles or bioturbation.
• It occurs as metasomatic replacement in granitic pegmatites and within phosphatic nodules in shales.
• Although these thick beds can exist they are rarely only composed of phosphatic sedimentary rocks.
• In a uranium survey in 1959-1961, phosphatic sediments were discovered near Bakouma.
• It occurs as groups of radiating fine fibrous crystals within rock cracks of phosphatic ironstone.
• These rocks contain abundant fish fossils like sharks'teeth preserved within small phosphatic nodules.
• Discrete bands of phosphatic nodules ( commonly preserving fossils ), some pyrite and calcareous nodules.
• The company produces and sells phosphatic fertilisers of various grades, including Diammonium phosphate and Single Super Phosphate.
• Low Ca : P intake ratio is conducive to phosphatic ( e . g . struvite ) urolith formation.
• Phosphatic sedimentary rocks are commonly accompanied by or interbedded with shales, cherts, limestone, dolomites and sometimes sandstone.
• Its mollusc shell is unique, because " Cobcrephora " was described on the basis of isolated phosphatic sclerites.
• Punctae or tubes penetrate through multiple shell wall layers, and individual punctae often develop a single, axial phosphatic tube.
• The blackcurrant is a gross feeder and benefits from additional nitrogen, and phosphatic and potash fertilisers should also be applied annually.
• Small phosphatic-shelled animals called brachiopods inhabited these tidal flats but as far as is known, nothing lived on land.
• In other words, the word pristine is used when phosphatic sediment, phosphatized stromatolites and phosphate hardgrounds have not been disturbed.
• Other environmental factors change around this time : Phosphatic units disappear; and there s a stem change in organisms'shell thickness.
• The mineral can be found in phosphatic shales and was first discovered in the Big Fish River area in Yukon Territory, Canada.
