: Geological studies and tomographic profiles of a locality nearby the Agoudal village (Morocco) showed the presence of a single impactcrater, 500600m diameter, largely hidden by a limestone block, 220m long and 40m deep. The site was interpreted as a landslide that followed the fall of a cosmic body. The Agoudal impact crater was not affected by intense erosion. The lack of an evident impact structure, as well as the sporadic distribution of impactites and their limited occurrence, can be explained by a complex geological framework and by recent tectonics. The latter is the result of the sliding of limestone block, which hides almost two-thirds of the crater's depression, and the oblique fall of themeteoroidon sloping ground. In addition, some impactbrecciadikes sharply cut the host rock in the Agoudal impact structure. They do not show any genetic relationship with tectonics orhydrothermal activity, nor are they related to anykarstorcalcreteformations. Altogether, the overlapping of themeteoritestrewn field (11km long and 3km wide) with the area of occurrence ofshatter conesand impact breccias, together with the presence of meteorite fragments (shrapnel) ejected from the crater, the presence of shatter conescontaminatedby products ofiron meteoritesand the presence of impact breccias that contain meteorite fragments of the same chemical composition of the Agoudal meteorite indicate that the fall of this meteorite can be responsible for the formation of the impact structure.

Name:Agoudal This is an OFFICIAL meteorite name. Abbreviation:There is no official abbreviation for this meteorite. Observed fall:No Year found:2000 Country:Morocco Mass:100 kg Classification history:Meteoritical Bulletin:MB 102(2013)Iron, IIABRecommended:Iron, IIAB[explanation] This is 1 of 140 approved meteorites classified as Iron, IIAB.[show all] Search for other:IIAB irons,Iron meteorites, andMetal-rich meteorites Comments:Approved 27 Apr 2013Writeup Writeup fromMB 102: Agoudal3159.074N,530.917W Centre-South, Morocco Found: 2000 Classification: Iron meteorite (IIAB) History: (H. Chennaoui Aoudjehane, M. Aboulahris,FSAC) Two small pieces of iron were collected in 2000 in the Agoudal area, High Atlas Mountains, Morocco, and sold to tourists. In September 2011, one piece was sold to a dealer in Errich, who recognized it as an iron meteorite. During the last months of 2012, systematic searching by meteorite hunters with metal detectors resulted in the discovery of a large number of meteorites, mostly small. Many pieces were collected on the surface or buried a few cm deep. The largest piece recovered was 60 kg, buried ~50 cm below the surface. On 9 February 2013, H. Chennaoui Aoudjehane, M. Aoudjehane and M. Aboulahris collected 200 g of specimens; the listed coordinates are those of the largest piece they recovered. The strewnfield is not yet clearly defined. Physical characteristics: Total mass is >100 kg. Hundreds of small pieces (1-100 g), many 100-1000 g, and a few pieces >1 kg, have been recovered. The majority of collected material occurs as 2-5 cm, irregularly shaped shrapnel pieces. Most pieces have a thin weathering rind. Some smaller bullet-shaped (~cm-sized) fragments are rounded, showing well-developed fusion crust. Petrography: (L. Garvie,ASU) Decimeter-sized pieces show a coarse pattern of irregular, interlocking kamacite grains; some grains with sub-boundaries. Widmansttten pattern not evident in the small sections studied. Grain boundaries commonly curved. Etched pieces range from shiny with well-developed Neumann bands, to pieces with a matte appearance, typical of the hatched -structure. The shock-hatched regions show incipient recrystallization, with secondary growth of irregularly-shaped (to 1 mm) kamacite. No plessite observed. Schreibersite abundant occurring as cm-sized skeletal crystals at the centers of kamacite crystals, as rhabdites, and as a grain boundary precipitate. Rhabdites locally numerous as sharp, 10-25 m faceted prisms. Scattered troilite nodules, to 1 cm. Troilite not surrounded by schreibersite, but instead large skeletal schreibersite is situated a few mm away. Heat-affected zone visible on some stones. Several of the smaller pieces, and especially the rounded bullet-shaped stones, have fusion crust and heated-affected zone of varying thickness; some completely recrystallized. Geochemistry: (C. Herd and G. Chen,UAb): ICP-MS data, Ni 5.5 wt%, Co 4.1 mg/g, Ga 58 g/g, Ir < 0.04 g/g and Au ~ 1 g/g. Classification: Iron, IIAB. Structurally similar toAinsworth.
