HaH 259 is a 5 kilogram chondrite found on the Hammadah al Hamra (the red plateau). The plateau extends 300 km from west to east, between Daraj and Brak in Libya. It has been prospected regularly since 1986, and with the discovery of over 450 meteorites, remains, after Dar al Gani, one of the top meteorite recovery spots of the Sahara.
This meteorite was waiting just a few hundred meters away from the cliff in the background.

This part of the Sahara is a huge sedimentary expanse, the site of ancient marine deposits recalling the oceans which covered it several tens of millions of years ago in the Cretaceous Period.
|
It is chiefly a stony landscape.

In chondrites, the visible metal is mainly a highly reflective iron alloy which contains a small amount of nickel. Troilite (FeS), an iron sulfide mineral is also present.

The distribution of meteorites currently stands at one for every 200 sq. km for the entire western region of the Hammada. It's not feasible to cover 2000 Km for a unique find as you would need to pass within 100m of a 1 Kg meteorite in order to have any hope of seeing one in situ. This would be equivalent to ten days of hard visual concentration and a hundred hours of prospecting. That's why, it is important to learn how to recognize the most favorable prospecting zones. Each find is the fruit of your labour and only serves to add to the experience.
Sixteen pieces, from 2 to 900 grams, were found around the main mass of 3.6 kilos. When several fragments are picked up on a very small area and if they appear to be broken fragments of the same meteorite, they are collectively brought together under a unique name and number. This rule does not apply to Antarctic finds where fragments from several different meteorites can be mixed, via wind action and ice movements, and gathered together on areas called Antarctic meteorite stranding surfaces. Each fragment is individually named and the Antarctic database is full of small pieces, some of which are only a few grams in weight.

Although ninety (90%) of meteorite falls are chondrites (stony meteorites), their mass represents only 15% of the extraterrestrial material discovered on Earth. The majority of meteorites in exhibition, some 300 tons, are iron meteorites. Structurally more dense and solid compared to chondrites, iron meteorites are able to withstand the rigors of atmospheric entry with minimal effect and thus are better able to withstand the ravages of time.
