Analyses of the Structural and the Temperature-Dependent Magnetic Properties of Pine Resin and Pine Bark from the Oltu/Erzurum Region in Turkey

In the present paper, our aim is to investigate the structural, compositional and temperaturedependent magnetic properties of pine resin and pine bark obtained from a yellow pine forest situated in Oltu/Erzurum, a tertiary depositional area, located on the central area of the Northeast Anatolian Fault Zone. With the purpose of understand the regional effects on pine resin and pine bark obtained from a yellow pine forest, electron paramagnetic resonance spectroscopy is used to determine paramagnetic features at different temperatures (room temperature, 65 au broken vertical bar C, 75 au broken vertical bar C and 85 au broken vertical bar C). An X-ray diffraction experiment is performed to obtain the crystalline nature of the resin and the bark. Also, scanning electron microscopy and energy dispersive spectroscopy methods are preferred for analyzing the surface morphology and the elemental composition of the samples, respectively.
