Pillistfer - EL6 Enstatite Chondrite

Pillistfer is a historic witnessed EL6 Enstatite Chondrite fall from Estonia, which occurred on 8 August 1863 near Pilistvere. It is one of only a small number of approved meteorites from Estonia and is especially important as the first recorded Enstatite Chondrite fall. With a reported total recovered mass of around 23.25 kg, Pillistfer remains one of the most significant EL Chondrite falls in meteorite history.

Pillistfer specimens are classified as EL6, meaning they belong to the low-iron branch of Enstatite Chondrites and have experienced a high degree of thermal metamorphism. Enstatite Chondrites formed under highly reduced, oxygen-poor conditions, giving them mineralogy that differs strongly from Ordinary Chondrites. As a type 6 meteorite, Pillistfer generally shows a recrystallised texture with subdued original Chondritic features, while retaining the distinctive chemical character of its group.

Studying Pillistfer provides valuable insight into reduced formation environments in the early solar system and the evolution of Enstatite Chondrite parent bodies. Its witnessed fall status, Estonian provenance, historic importance, and rare EL6 classification make it especially desirable for collectors of classic falls and uncommon Chondrite groups. Each specimen represents ancient asteroid material connected to one of the earliest documented Enstatite Chondrite falls.
