Trevorite is a rare nickel iron oxide mineral belonging to the spinel group. It has the chemical formula NiFe 3+ 2 O 4. It is a black mineral with the typical spinel properties of crystallising in the cubic system, black streaked, infusible and insoluble in most acids.

Named after Major Tudor Gruffydd Trevor (1865 – 1954), mining inspector for the Pretoria District, Transvaal, South Africa, where the species was first found. This page provides mineralogical data about Trevorite. As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams.

镍磁铁矿（英語： Trevorite ）是一种稀有的镍 铁 氧化物矿物，属于尖晶石族。 它的化学式为NiFe 3+ 2 O 4 。 它是一种黑色矿物，具有典型的尖晶石特征 立方晶系 结晶，有黑色条纹，不溶于大多数酸。

一个 晶胞 可分成8个小 立方体，共面的小立方体是不同类型的，即质点排列情况不一样；而共棱的小立方体是相同类型，质点排列情况一样，换句话说尖晶石的晶胞是由8个小块拼合而成，分两种情况：A块、B块。 A块主要显示Mg 2+ 占据 四面体空隙，B块主要显示Al 3+ 占据 八面体空隙。 A块离子排列情况? 4个O 2- 位于顶角和面心处，即O 2- 作面心立方堆积。 3/2个Al 3+ 位于6条边中心，即处于O 2- 堆积体的八面体空隙中。 2个Mg 2+ 在一条 对角线 方向，与三个面心处和一 …
