Definition of tridymite in English:
A high-temperature form of quartz found as thin hexagonal crystals in some igneous rocks and stony meteorites.
- Although the optical, SEM, and XRD data are consistent with quartz, considering the incongruous crystal symmetry, it is likely that this mineral is actually a quartz pseudomorph after tridymite.
- The abundant and ubiquitous quartz paramorphs after tridymite in the walls attest to a very shallow emplacement depth.
- Quartz paramorphs after tridymite are absent from Fiachanis but present in the three Priomh-lochs samples adjacent to late minor intrusions.
