Mineralogy of sulfides [PDF]

, 2017
Metal sulphides are the most important group of ore minerals. As shown in this brief introduction, much is known about their compositions, crystal structures, phase relations and paragenesis.

Magnetic structure and exchange interactions in pyrrhotite end member minerals: hexagonal FeS and monoclinic Fe ₇ S ₈

Journal of Physics: Condensed Matter, 2021
Abstract Iron mono-sulphides, or pyrrhotites, are minerals present in the Earth’s crust and mantle as well as major magnetic constituents of several classes of meteorites, thus are of interest to a wide range of disciplines including geology, geophysics, geochemistry, and material science.

Magnitostratigraphic studies of the Upper Sarmatian-Lower Maeotian deposits in the Panagia Cape section (the Taman Peninsula)

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
In order to obtain the missing data on the magnetostratigraphy of transitional layers between Sarmatian and the Maeotian parts in the Eastern Paratethys, the authors studied the Upper Sarmatian ― the Lower Maeotian deposits in the Panagia Cape section ...

Thermoremanence in monoclinic pyrrhotite particles containing few domains

Geophysical Research Letters, 1998
The intensity and stability of thermoremanent magnetization (TRM) acquired by synthetic Fe7S8 particles in the size range 1‐29 µm has been determined. The intensity falls with increasing particle size. The unblocking temperature increases with increasing particle size.

Magnetic Hysteresis Properties of Fine Particles of Monoclinic Pyrrhotite Fe7S8.

Journal of geomagnetism and geoelectricity, 1997
The magnetic hysteresis properties have been studied of synthetic Fe7S8 separated into a suite of 8 particle size fractions in the range 1 to 30μm. Between-196°C to about 260°C, both saturation isothermal remanence (Mrs) and coercive force (Hc) can be represented as analytical functions of particle size (L) of the form (Mrs, Hc) ∝ L-n or (Mrs, Hc ...
