This paper presents the preliminary results of investigations of carbonate nodules from red paleosols of the reference sections of the Middle and Upper Permian of the Kazan Volga region. The main genetic types of paleosols are calcic gleysols and gle

The purpose of this work is to use methods of magnetic radiospectroscopy – electron paramagnetic resonance (EPR) and low-field nuclear magnetic resonance (NMR LF) to determine the quality of the rocks of fluid seals of “lingul clays” (depth 82-

Gypsum crystals were formed from a saturated solution of produced water remaining in the horizontal section of the discharge pipe and cause undesired (side) man-made phenomenon as clogged pipe. However, for scientific purposes, this fact has become u

The electron spin resonance (ESR) spectra of SO 3 − and SO 2 − radical ions with a linewidth ΔH ≈ 2.7 G and SO 3 − (A 1) and SO 3 − (A 2) centers with superhyperfine splitting due to the interaction with protons in platelike gypsum single

The conditions for equivalent positions on the (hkl) face of growing crystal are derived using symmetry elements of the space group. It is shown by the example of the sp. gr. D2h16 that the conditions of equivalent position formation coincide with co

On the basis of the analysis of the electron spin resonance spectrum of the SO 3 − radical ion, it is established that the transformation of gypsum (CaSO4 · 2H2O) into bassanite (CaSO4 · 0.5H2O) with partial removal of water molecules occurs thro

The EPR spectra of Fe3+ impurity ions in NaZr2(PO4)3 single crystals at 300 K are investigated, and the spin Hamiltonian of these ions is determined. A comparative analysis of the spin-Hamiltonian and crystal-field tensors is performed using the maxi

An electron paramagnetic resonance (EPR) study of a synthetic single crystal of LiScGeO4 doped with Cr ions carried out earlier at the X- and Q-bands at 300, K has indicated additional weak lines. A detailed analysis of these EPR lines, which were te

An electron paramagnetic resonance study of a synthetic single crystal of Cr-doped LiScGeO4 was carried out at the X- and Q-bands at 300 K and at the broad band (70-370 GHz) at 4.2 K. It was established that the EPR spectra with the magnetic multipli

In single crystals of LiCaAlF6 and LiSrAlF6 doped with Fe3+ the trigonal EPR spectra with multiplicityK M = 1 were observed due to Fe3+ substituted for Al3+. The spin Hamiltonian parameters describing the fine structure and the superhyperfine structu
