Tiglit - Enstatite Achondrite (Aubrite)

Tiglit is a rare witnessed Aubrite fall from southern Morocco, which occurred on 9 December 2021. Aubrites are Enstatite Achondrites, formed under highly reduced, oxygen-poor conditions on an early differentiated parent body. Tiglit is especially notable as a modern Aubrite fall, giving researchers access to fresh material from a meteorite group that is already uncommon. The Meteoritical Bulletin records Tiglit as an approved fall from Morocco, published in Bulletin 111.

 

Tiglit specimens are typically pale to light-coloured, consistent with Enstatite-rich Aubrites, and may show areas of tan to brown fusion crust. Petrographic descriptions indicate that Enstatite makes up around 90 to 95 percent of the meteorite, with scattered Diopside and Olivine grains also observed. Recent analytical work has confirmed the presence of Enstatite, Olivine, Plagioclase, sulfides, carbon phases, iron oxides, calcite, and silica polymorphs, adding further scientific interest to its mineralogy.

 

Studying Tiglit provides valuable insight into Aubrite formation, highly reduced parent bodies, and the preservation of fresh Enstatite Achondrite material after a witnessed fall. Its modern fall status, Moroccan provenance, rare classification, and distinctive pale mineralogy make it especially desirable for collectors of Achondrites and witnessed falls. Each specimen represents ancient igneous material formed under unusual conditions in the early solar system, delivered to Earth in a clearly documented event.
