.... However, it is highly unusual to find unmelted crystals from the actual impactor within an ejecta layer. Here we detail the first recorded occurrence of vanadium-rich osbornite (TiVN) on Earth, from two sites on Skye, northwest Scotland, which are interpreted as part of a meteoritic ejecta layer. TiVN has...

... loadings, then we will observe a large amount of spinel-type Si 3 N 4 . Therefore the present results indicate that sinoite does not decompose under shock. Finally we make a note on osbornite TiN that is considered to be a nitrogen source for the formation of sinoite. TiN is easily oxidized into rutile...

.... Type N ( Fig. 4 ) is represented by osbornite (TiN, 12.5%–16% N; Table 1 ). The unnamed boride TiB 2 is intergrown with TiN; the identity of both phases is confirmed by electron diffraction ( Table 1 ). Type N assemblages may occur alone in complex three-dimensional (3-D) networks or intergrown...

... (CaS) and osbornite (TiN). Bustee is of the group of stony meteorites called aubrites, and these specimens, along with their chondritic counterparts the enstatite meteorites, are characterized by being so chemically reduced that many cations become siderophile (i.e. form into sulphides).
