Origin of Mineralizing Fluids in the Choghart Magnetite-Apatite Deposit, NE of Bafq: Evidence from Mineralogy, Geochemistry, Microthermometry, Stable (O-H and O-C) and Unstable Isotopes (U-Pb and Nd-Sm)

open access: yesJournal of Economic Geology, 2022
Introduction The Bafq mining district (BMD) in the Kashmar-Kerman tectonic zone hosts ~34 magnetite-hematite-apatite ore deposits with about 1500 Mt of reserves in the central Iran (Torab, 2008).

Geochemistry of apatite in various felsic rocks of the Piranshahr plutonic complex: an approach to investigate magmatic evolution [PDF]

open access: yesعلوم زمین خوارزمی, 2023
The felsic intrusive rocks in the Piranshahr plutonic complex consist of three groups: syenite, nepheline-syenite, and alkali-feldspar granite. They are co-genetic and formed approximately 40 million years ago.

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Simultaneous incorporation of magnesium and carbonate in apatite: effect on physico-chemical properties [PDF]

open access: yesMaterials Research, 2013
Synthetic apatites are widely used both in the dental and the orthopaedic fields due to their similarity in composition with the inorganic phase of hard tissues.

Physico-chemical properties of nanocrystalline apatites: Implications for biominerals and biomaterials [PDF]

open access: yes, 2007
Nanocrystalline apatites play an important role in biomineralisation and they are used as bioactive biominerals for orthopaedic applications. One of the most interesting characteristics of the nanocrystals, evidenced by spectroscopic methods, is the ...
