摘要: Transmission electron microscopy on the iron monosulfide (FeS) varieties from Suizhou meteorite (Hubei, China) reveals intergrowth of primary hexagonal 2C troilite \( {\left( {{\text{SG}}:P\ifmmode\expandafter\bar\else\expandafter\=\fi{6}2c} \right)} \) and minor monoclinic 4C pyrrhotite (SG: F2/d) phases as nanometer-scale domain microstructure. In addition, anti-phase boundaries are found to present in superstructure with displacement vector 1/4[001]2C, which is expected form during translational symmetry breaking cooling higher symmetry, high-temperature modification NiAs-type P63/mmc) structure. Furthermore, 60° rotation twinning about pseudo-hexagonal c-axis observed superstructure, may result reduction induced by ordered arrangements metal vacancies through solid-state transformation further cooling. All above microstructural characteristics discussed consideration thermal metamorphism history experienced meteorite.
