Technical note: LA–ICP-MS U–Pb dating of unetched and etched apatites [PDF]

open access: yesGeochronology, 2021
The same unetched and chemically etched apatite crystals from five rock samples were dated by the U–Pb method via laser ablation inductively coupled plasma mass spectrometry (LA–ICP-MS).

Direct Calibration Method for LA-HR-ICP-MS Apatite U-Pb Dating

open access: yesYankuang ceshi, 2022
BACKGROUND Apatite is a common U-bearing accessory mineral with a U-Pb closure temperature of ~500℃, making U-Pb dating of apatite a potentially valuable thermochronometer.

Polysomatic apatites [PDF]

open access: yesActa Crystallographica Section B Structural Science, 2010
Certain complex structures are logically regarded as intergrowths of chemically or topologically discrete modules. When the proportions of these components vary systematically a polysomatic series is created, whose construction provides a basis for understanding defects, symmetry alternation and trends in physical properties.

Behavior of apatite in granitic melts derived from partial melting of muscovite in metasedimentary sources

open access: yesChina Geology, 2021
: Fluid-absent and fluid-fluxed melting of muscovite in metasedimentary sources are two types of crustal anatexis to produce the Himalaya Cenozoic leucogranites.

APATITE OF ALKALINE ROCKS OF THE VISHNEVOGORSKY COMPLEX, SOUTH URALS [PDF]

open access: yesМинералогия, 2019
Apatite Ca5(PO4)3(F,Cl,OH) is a widespread accessory mineral of alkaline rocks of the Vishnevye Mountains in the Urals. There are small bodies of carbonatites and micaceous rocks, where apatite is a rock-forming mineral.

Apatite formation on electrochemically modified surface of hafnium metal in simulated body environment

open access: yesJournal of Asian Ceramic Societies, 2022
Biomedical application of Hf for hard tissue repair may be expanded if it can be imparted with bone-bonding ability. Apatite formation in the body is required for artificial materials to bond to bone. We have shown that apatite can form on NaOH- and heat-

Mineralization Behavior of the Petal-Like Apatite/TiO2 Composite Coating Prepared by Micro-Arc Oxidation

open access: yesInternational Journal of Electrochemical Science, 2012
The mineralization behavior of the petal-like apatite/TiO2coating, which was prepared by micro-arc oxidation (MAO) on the surface of the commercially pure titanium, was studied in simulated body fluid (SBF).

Triclinic apatites

open access: yesActa Crystallographica Section B Structural Science, 2007
Apatites commonly adopt P63/m hexagonal symmetry. More rarely, monoclinic chemical analogues have been recognized, including the biologically significant hydroxyapatite, Ca10(PO4)6(OH)2, but the driving force towards lower symmetry has not been systematically examined.
