Main Mass H4 OC meteorite from the Sahara Desert, Northwest Africa, weighing 476 g, with well-preserved fusion crust and chondrules.

AI-assisted summary

Description from the seller

A truly superb H4 OC meteorite from the Sahara Desert, weighing 476 grams and showing a well-preserved primary fusion crust, regmaglypts, secondary fusion crust, and abundant, well-defined, unequilibrated chondrules and CAIs.

This is one of my most recent classifications, and you will be buying from the main mass holder. Except for the type specimen required for classification and a few small sections which will remain with me, this is all there is of this meteorite.

The buyer will also receive (upon request) a few microscope thin-section, cross-polarised light images taken by the classifier, showing various types of chondrules and the matrix of the specimen.

I am a member of the Meteoritical Society (#7743) and have been collecting meteorites for over 15 years.
