Introduction: schreibersite is an accessory mineral in most iron meteorites and many stony ones. It has also been observed in lunar samples, possibly of meteoritic origin.
Occurrence in Wales: Graham et al. (1977) noted that schreibersite is present within the Pontlyfni meteorite, which fell at 11.53 am on 14 April 1931 at Coch-y-Bug farm, 7.5 miles SSW of Caernarvon in North Wales. No further details are provided.
Key Localities:
- Coch-y-Bug Farm, Pontllyfni, Gwynedd: schreibersite is briefly mentioned by Graham et al. (1977) as present within the Pontlyfni meteorite.
