Apatite thin section - Non-silicates - MicROCKScopic
Apatite thin section photomicrographs are taken in plane-polarized light and cross-polarized light, and can easily be recognized under the microscope.
Apatite - ALEX STREKEISEN
Apatite - Ca 5 (PO 4) 2 [F, OH, Cl] Apatite structure is characterized by phosphate oxyanion linked by Ca 2+ cations to forma hexagonal frame-work with F-anions lying at the corners of hexagonal cell and coordinated by three Ca 2-cations.
Minerals | Virtual Microscope
Apatite is a common accessory mineral in igneous and metamorphic rocks. It is one of the first minerals to form or crystallize from a magma, hence it is commonly found as mineral inclusion in larger minerals such as biotite and pyroxenes. Apatite occurs as tiny rounded or …
Apatite - Clark Science Center
Found mainly in various igneous and metamorphic rocks, however they are found in carbonatites and sedimentary rocks. Due to the phosphate content, apatite crystals are usually small and can be hard to detect in thin section. Editors: Anna Marchefka ('02), Emmy Smith ('08), Jen Axler ('11)
How do I identify apatite under a reflected microscope?
Under-transmitted light apatite shows mainly colourless, low to moderate relief, weak birefringence, prismatic crystals and rounded oblong grains showing parallel extinction.

Identification, Characterization and Properties of Apatites
2016年1月8日 · Ionic surfactants, such as decyltrimethylammonium bromide (CH 3 (CH 2) 9 N(CH 3) 3 (Br), C(10)TAB), hexadecyltrimethylammonium bromide (CH 3 (CH 2) 15 N (Br)(CH 3) 3, C(16)TAB), as well as nonionic surfactant, can be used to control the pore (pore size and volume) and surface characteristics of mesoporous apatite materials under maintained pH .
Apatite - ALEX STREKEISEN
Apatite is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH-, F-and Cl-ions. Apatite structure is characterized by phosphate oxyanion linked by Ca 2+ cations to forma hexagonal frame-work with F - anions lying at the corners of hexagonal cell and coordinated by ...
