| It is found with other rare earth elements in minerals such as monazite, cerite, gadolinite, xenotime, and euxenite. |
|
| The monazite grains are located along fractured mica foliation planes that run along the base of larger metamorphic minerals. |
|
| The sample contains graphite, but no monazite was found in the heavy mineral concentrates. |
|
| It occurs primarily with the other rare earth elements in two minerals, monazite and bastnasite. |
|
| Lower amphibolite-grade regional metamorphism predating intrusion of the Ballachulish Igneous Complex may have resulted in some monazite growth. |
|
| Other accessory minerals are apatite, zircon, monazite, huttonite and rare xenotime, uraninite and betafite. |
|
| Eighteen analyses of detrital zircon and one of monazite were carried out for the late Silurian sandstone. |
|
| It left with 23,000 tons of sifted monazite, bound ultimately for the airship works at Cardington. |
|
| The unusual age zonation is probably linked to the mineralogical association of monazite and apatite during metamorphic reactions. |
|
| The monazite crystals range from reversely discordant to within error of concordant to slightly normally discordant. |
|
| Initial monazite growth at staurolite facies conditions takes place during prograde conditions. |
|
| Xenotime is a phosphate mineral, similar to monazite except enriched in the heavy lanthanides and yttrium. |
|
| The most common ores of holmium are monazite and gadolinite. |
|
| After separation, monazite and silica sands will be returned to the deposit. |
|
| Finally, a U-Pb isotopic study of zircon and monazite from khondalite and sapphirine granulite was undertaken as a more reliable method for dating the metamorphic event. |
|
| Detrital monazite will not survive sedimentary recycling as well as zircon, so it provides a better estimate of the age of the most recent terrane erosion. |
|
| Xenotime contains smaller amounts of the radioactive compounds U3O8 and ThO2 than monazite. |
|
| Kyanite, microcline, zircon, monazite and opaque minerals are variably present with epidote, actinolite and chlorite being present as secondary alteration minerals. |
|
| Sillimanite, cordierite, apatite, monazite and zircon are also present. |
|
| Less commonly found in minable concentrations are gold, diamonds, cassiterite, scheelite, wolframite, monazite, and platinum. |
|
|
|
| Textures of kyanite, xenotime and monazite, and some staurolite and biotite, indicate that peak metamorphic mineral growth occurred after D 2 deformation. |
|
| Zircon, monazite, xenotime and white mica were extracted from the sample. |
|
| I dutifully explained that the smoky spots were probably the result of natural irradiation caused by many tiny radioactive mineral grains, possibly monazite or xenotime. |
|
| Minerals of rare earths present in this prospect are monazite and fluorapatite, thin veins of fluocarbonate in calcite and dolomite deposits. |
|
| Petrographic studies show that this concerns stripped carbonatites that extend to 900 m with metric thicknesses and that show a mineral association with monazite. |
|
| Schlieren consists of biotite, amphibole, zircon, allanite, monazite, magnetite, and fluorite. |
|
| Areas with large amounts of thorium-rich monazite sands tip the scales when it comes to background radiation. |
|
| Identification of multiple rare earths and associated elements in raw monazite sands by laser-induced breakdown spectroscopy. |
|
| In India there are quite a few monazite sand bearing placer deposits causing high background radiation along its coastline. |
|
| As the magma cools, REE elements eventually become concentrated in accessory phases such as zircon, rutile, ilmenite, titanite and monazite. |
|
| This sector includes mining of titanium-bearing minerals such as rutile, leucoxene, ilmenite, xenotime and monazite, and the industrial minerals zircon, kyanite and garnet. |
|
| Accompanying heavy minerals commonly include variable quantities of monazite, magnetite, ilmenite, cassiterite, wolframite, scheelite, cinnabar, and platinoid minerals. |
|
| Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite. |
|
| As a crucial strategic resource, it is mainly contained in bastnaesite, xenotime, monazite, and other minerals. |
|
| Kyanite, garnet, monazite, and amphibole are common minerals, while apatite, anatase, titanite, corundum, pyroxene, and epidote are rare. |
|
| Lanthanum is a rare-earth trace metal that naturally occurs in monazite sand and coal. |
|
| Beach placer deposits of India essentially consist of ilmenite, rutile, garnet, zircon, monazite, sillimanite and quartz. |
|
| The Hamhung plant reportedly has the capacity to process 1,500 tons per year of monazite, from which 400 tons of rare earth metals and oxides can be processed. |
|
| The monoclinic, monazite structure, orthophosphates show a higher degree of Pb incorporation than the tetragonal xenotime structure, orthophosphates. |
|
| Monazite clusters occur in a variety of host minerals, including cordierite, quartz, biotite and andalusite. |
