    Apatite in carbonatitic rocks: Compositional variation

    01/03/2017· Abundant detrital apatite, accompanied by magnetite, baddeleyite, pyrochlore or columbite, suggests early removal of rare earths from carbonatitic magma and, hence, is an indicator of low REE potential of the substrate rock; (4) Igneous apatite from carbonatites and other rock types can be distinguished reliably using a variety of criteria (i.e

    APATITE (Calcium (Fluoro-, Chloro-, Hydroxyl-) Phosphate)

    Apatite is widely distributed in all rock types; igneous, sedimentary and metamorphic, but is usually just small disseminated grains or cryptocrystalline fragments. Large well formed crystals though can be found in certain contact metamorphic rocks. Very gemmy crystals of apatite can be cut as gems but the softness of apatite prevents wide distribution or acceptance of apatite as a gemstone

    RESEARCH INTO THE USE OF APATITE ROCK FOR ACIDIC

    If apatite rock is thoroughly admixed with spoil, it will be exposed to the ambient environment, whether neutral, basic, or acidic. If no acid occurs, the phosphate material would remain relatively dormant within the spoil. However, when, or if, pyrite oxidation (by whatever means) occurs, the acidic condition generated would dissolve the phosphate material (apatite). The released phosphate

    Apatite Composition: Tracing Petrogenetic Processes in

    Regardless of rock type, apatites from metaluminous Transhimalayan rocks have lower contents of the HREE (Gd to Lu plus Y: 100–2000 ppm) than apatites from peraluminous granites (400–10 000 ppm), although both groups of apatite have similar light REE (LREE) contents (La to Eu: mostly 1000–10 000 ppm).
