124g El Eglab Mesosiderite Meteorite – Full Slice with Translucent Features and Intact Barred Olivine Chondrule

This is an exceptional full slice of the El Eglab Mesosiderite, weighing 124 grams. Known for its strikingly unique composition and aesthetic appeal, this specimen showcases the rare and enigmatic nature of mesosiderites — a class of stony-iron meteorites believed to have formed from the collision between a stone meteorite and an iron-rich body.

What sets this slice apart is its beautiful natural translucency, which is especially visible when backlit, and its elegant, well-preserved shape. Adding further scientific and collector value, the specimen contains a clearly visible barred olivine chondrule, remarkably still intact — a feature occasionally seen in El Eglab mesosiderites, but always prized for its implications on the complex history of these meteorites.

Mesosiderites continue to puzzle planetary scientists due to their mixed composition and ambiguous formation processes. This slice exemplifies that mystery, blending metallic and silicate elements in a dramatic and visually compelling way.

A superb addition for serious collectors, academic institutions, or anyone seeking a truly unique extraterrestrial specimen.

About Mesosiderites

Mesosiderites are a rare and enigmatic class of stony-iron meteorites, composed of approximately equal parts metallic nickel-iron and silicate rock, often including pyroxene, olivine, and plagioclase. They are now widely believed to have formed through catastrophic collisions between differentiated planetary bodies—a stony body and a metallic one—that partially melted and re-accreted under extreme heat and pressure.

This violent origin explains their brecciated structure, complex mineralogy, and the presence of melt veins and mixed components from both core and crustal material. Unlike other meteorite classes, mesosiderites remain one of the most mysterious in terms of their exact origin and timeline, making every specimen a valuable scientific puzzle piece.

The El Eglab mesosiderite in particular is one of the most unique examples in the mesosiderite family, with characteristics that strongly support the impact hypothesis and offer insight into the dynamic early history of our solar system.
