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.

Recent research progress of luminescent materials with apatite structure: A review

open access: yesOpen Ceramics, 2022
Phosphors with apatite structure have shown potential applications in solid-state lighting and display industry due to their flexible crystal structure, controllable chemical composition and different crystallographic positions of single doped or co ...

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.

TOWARDS A SAFETY ENVIROMENT: HOW APATITE MINERALS REMEDIATE Pb, Zn and Mn FROM WASTE WATER? [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2010
To evaluate the effectiveness of apatite minerals in removing different contaminants, from low quality water in the industrial city of abha, Asir region, southwestern of Saudi Arabia, two phosphatic clay dominated by apatite mineral were selected.

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-

U–Pb Dating, Gemology, and Chemical Composition of Apatite from Dara-e-Pech, Afghanistan

open access: yesCrystals, 2023
Minerals of the apatite group commonly occur in granite pegmatites, and their ability to incorporate a wide range of trace elements makes them a good indicator of magma composition and magmatic–hydrothermal processes.

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).
