Since the first recorded discovery of a meteorite in 1937 near the Mrirt village (Khenifra, Morocco), a total of 946 authenticated meteorites have been recorded in Morocco. The material, including 10 observed falls, comprises 918 stones, 13 irons and 15 stony-irons. A low ratio of falls to finds (represent only 0.01 % of the Moroccan declared meteorites) compared with other countries (e.g., USA 14.3 %). However the rate of recovery of meteorites (falls + finds) in Morocco exceeds that of most other countries of similar size and range of climatic conditions. More than 95 % of documented meteorites from Morocco have been recovered from Eastern Morocco (Eastern Sahara Moroccan) including many rare types. This Region has proved to be one of the most prolific areas in the world for meteorite finds.

New meteorite prospections at different places in the region of Imilchil showed that (1) besides the Ataxite of Tasraft all the other collected specimens belong to the same and only IIAB iron mother meteorite (2) the strewn field of the meteorite has a length of about 38 km into north-south direction (3) the small crater of Agoudal as well as the impact crater of Isli are situated on a parallel north-south axis, if not put together with the strewn field of the Imilchil meteorite (4) these two structures might be the result of the fall of the same and only mother meteorite of the IIAB type.

The Tissint fireball is the only fireball to have been observed and reported by numerous witnesses across the south-east of Morocco. The event was extremely valuable to the scientific community; show an extraordinary and rare event and were also the brightest and most comprehensively observed fireball in Morocco’s known astronomical history. Since the abstract of A. Ibhi (2011) [1]. In 1012-2013 concerning a number of Martian meteorite fragments found in the region of Tata (Morocco), a number of expeditions have been made to the area. A. ibhi has done a great amount of field work. He discovered the strewn field and collected the fragments of this Martian meteorite and many information. Each expedition has had the effect of expanding the size of the strewn field which is now documented to cover more than 70 sq. kilometers. The size of the strewn field is now estimated to be about a 17 km long.

During the last eighty years, thirteen meteorite falls were recorded in Morocco, which ten are well documented and named Douar Mghila, Oued el Hadjar, Itqiy, Zag, Bensour, Oum Dreyga, Benguerir, Tamdakht, Tissint and Aoussred. It represent only 0.011 % of the Moroccan declared meteorites.The authenticated observed falls represent three types of different meteorites, eight ordinary chondrites (Four of type LL, three of type H and one of type EH), one carbonaceous chondrite and one Shergottite basaltic achondrites. The Morocco meteorite fall recovery rate, during the past eighty years, is low 0.11 falls per year on average per 2.11 km2 (or approximately one fall recovery per 10 year time interval).
