Considering the high potential of the Lut Desert in meteorite preservation, systematic works should lead to the discovery of more samples giving access to interesting material for future studies. Measurements of terrestrial age ( 14C) show a range of 10–30 ka, which is in the range of ages reported for meteorites from other hot deserts except the Atacama Desert (Chile). The weathering effects observed in the Lut Desert OCs can be used as distinctive indicators to distinguish them from meteorites from other regions of the Earth. The total carbon and CaCO 3 is higher than in samples from other hot deserts. Meanwhile, a decrease in the V, Cr, Co, Rb (and possibly Fe) due to terrestrial weathering is detectable. Mobile elements, such as Li, Sr, Mo, Ba, Tl, Th, and U, are enriched with respect to fresh falls. Magnetic measurements and X-ray diffractometry confirm the occurrence of terrestrial weathering products, with the dominance of maghemite, goethite, and hematite. A rather unusual type of troilite weathering to pyrite/marcasite is observed in most of the Lut Desert meteorites. The temperature of 70.7 has been recorded within the property. The unique features that Lut Desert deserve to be inscribed on this list are: The highest and longest Kalut (Yardang) in the world. Fe,Ni metal (hereafter simply metal) and troilite are transformed into Fe oxyhydroxides. Lut Desert which is located in three provinces of South Khorasan, Kerman, and Sistan & Baluchestan, has occupied 10 of Iran’s area. A detailed study of the geochemistry and mineralogy of selected meteorites reveals significant effects of terrestrial weathering. The second are well-preserved paired L5 also found in Kalut region. The most abundant by far are the highly weathered paired H5 distributed in the northwest of Kalut area (central Lut, Kerman dense collection area). All the collected meteorites are ordinary chondrites (OCs). ![]() Here, we report on their classification, spatial distribution, and terrestrial weathering. Our search campaigns, alongside with the activity of meteorite hunters, yielded >200 meteorite finds. We present for the first time a detailed report on the discovery of a new meteorite collection region in the Lut Desert, eastern–southeastern Iran, describing its geological, morphological, and climatic setting.
