Synthesis, crystal structure and structure–property relations of strontium orthocarbonate, Sr2CO4

Acta Crystallographica Section B, Volume 77, Issue 1, Page 131-137, February 2021., 2021
A new orthocarbonate, Sr2CO4, was synthesized under extreme pressure and temperature conditions of 92 GPa and 2500 K, respectively. The crystal structure of the compound s fully characterized in situ by synchrotron single‐crystal X‐ray diffraction and DFT calculations were employed to provide insight into its equation of state, Raman and IR spectra ...

Genesis of Tozlou Pb-Zn Occurrence (South of Zanjan): Evidence from Geology, Mineralization, and Geochemistry

Journal of Economic Geology, 2023
Tozlou Pb-Zn mineralization, ~250-300m long, and ~50m thick, is hosted by limestone units of the Qom Formation. The main mineralization zone occurred as vein-veinlets and vug infill textures, where mineralization is observed as Pb-Zn-bearing barite veins
