Reconstruction of the depositional sedimentary environment of Oligocene deposits (Qom Formation) in the Qom Basin (northern Tethyan seaway), Iran [PDF]
Geologos, 2020 Abstract During the Rupelian–Chattian, the Qom Basin (northern seaway basin) was located between the Paratethys in the north and the southern Tethyan seaway in the south. The Oligocene deposits (Qom Formation) in the Qom Basin have been interpreted for a reconstruction of environmental conditions during deposition, as well as of the ...

Biostratigraphy and Microfacies of Qom Formation in Urumieh – Dokhtar Zone, Iran [PDF]
International Journal of Engineering and Technology, 2018 In order to determine the accurate paleoenvironmental conditions of Qom Formation, one stratigraphic section was studied in the Urumieh-Dokhtar Zone (West of Ashtian). 60 thin sections of the Qom Formation, 71 m thick, were prepared and the distribution of benthic foraminifera was analyzed.

Single-Crystal-to-Single-Crystal Transformation in a Copper(II) Complex: Structural and Spectroscopic Insights into Methanol Elimination and Hydrogen Bond Network Formation. [PDF]
ChemistryOpenA methanol‐ligated copper(II) complex undergoes a single‐crystal‐to‐single‐crystal transformation upon solvent loss, retaining crystallinity while reorganizing its coordination geometry and hydrogen‐bonding network. This study investigates the single‐crystal‐to‐single‐crystal (SCSC) transformations of a copper(II) complex, [Cu(L1)2(acac)2]·2CH3OH (1 ...
