WebJan 1, 2015 · The low‐temperature form of CuFe2S3, cubanite, has been identified in the CI chondrite and NASA Stardust mission collections. The presence of this mineral constrains the maximum temperature to 210 °C since the time of its formation. However, until now, the conditions under which cubanite forms were less well constrained. In order to refine the … WebAmong the wide family of copper-based sulfide compounds, cubanite (CuFe 2S 3) is a well-known weakly ferromagnetic mineral with an orthorhombic structure.39However, when heated above 473 K, the orthorhombic cubanite irreversibly transforms to a face-centered cubic polymorph, termed as isocubanite.39,40Analogous to chalcopyrites (CuFeS
