Ядро Земли состоит в основном из железа и никеля, образующих железо-никелевый сплав. В то же время сера является одним из потенциальных кандидатов на роль легкого элемента во внутреннем ядре. На сегодняшний день с помощью квантово-химического моделирования было проведено множество теоретических исследований для поиска промежуточных составов и структур в таких системах, как Fe-C, Fe-H, Fe-O, Fe-Si, Fe-S и Fe-P до давлений 400 ГПа.

Несмотря на обширные исследования систем железо-легкие элементы, на сегодняшний день не создана минералогическая модель ядра Земли, которая полностью соответствовала бы наблюдаемым сейсмологическим данным. Возможной причиной этого расхождения может быть недостаточный учет влияния ключевого легирующего элемента ядра – никеля. Теоретические исследования системы никель-легкие элементы при высоких давлениях были проведены недостаточно. Следовательно, необходимо провести более углубленные исследования этих бинарных систем с целью дальнейшего изучения и идентификации возможных промежуточных соединений в тройных системах Fe-Ni-S.

The core of the Earth consists mainly of iron and nickel, forming an iron-nickel alloy. At the same time, sulfur is one of the potential candidates for the role of a light element in the inner core. To date, many theoretical studies have been conducted by quantum chemical modeling to search for intermediate compositions and structures in systems such as Fe-C, Fe-H, Fe-O, Fe-Si, Fe-S and Fe-P up to pressures of 400 GPa.

Despite extensive research on the iron-light element systems, to date no mineralogical model of the Earth's core has been created that fully corresponds to the observed seismological data. A possible reason for this discrepancy may be insufficient consideration of the influence of the core's key alloying element, nickel. Theoretical studies for the nickel-light element system at high pressures have not been sufficiently carried out. Therefore, it is necessary to conduct more in-depth studies of these binary systems in order to further study and identify possible intermediates in triple Fe-Ni-S systems.
