description Pontlyfni Overview
Pontlyfni is a meteorite that fell near the village of Pontlyfni in Gwynedd, Wales, in 1931. It is classified as a winonaite, a rare type of primitive achondrite whose mineralogy records substantial heating and recrystallization without the complete differentiation seen in many other achondrites. Its observed fall makes it an important comparative specimen for researchers studying early asteroid evolution.
help Pontlyfni FAQ
What type of meteorite is Pontlyfni?
Pontlyfni is classified as a winonaite, a rare type of primitive achondrite. Its mineralogy records substantial heating and recrystallization without the complete differentiation seen in many other meteorite groups.
Where and when did the Pontlyfni meteorite fall?
The Pontlyfni meteorite fell near the village of Pontlyfni in Gwynedd, Wales, in 1931. It is one of the very few meteorites known to have fallen in Wales.
What is a winonaite meteorite?
Winonaites are a rare class of primitive achondrites that have undergone significant heating and recrystallization but retain some primitive chemical characteristics. Their mineralogy is intermediate between chondrites and fully differentiated achondrites, making them valuable for understanding early solar system processes.
How rare are winonaite meteorites like Pontlyfni?
Winonaites are among the rarest meteorite types, with only a small number of recognized specimens worldwide. Pontlyfni, as a witnessed fall from 1931 in Wales, is a particularly important example of this uncommon class.
