Abstract— As of July 2001, 1238 Libyan meteorites have been reported. Most were found in two areas called Dar al Gani and Hamadah al Hamra. Dar al Gani is located on a plateau of marine carbonate rocks with marly components. Eight‐hundred and sixty‐nine meteorites between 6 g and 95 kg totalling 687 kg have been found here but the calculated mean recovery density is comparatively low with one meteorite on 6.5 km2. 
Shişr 043 (IIIAB medium octahedrite): The first iron meteorite from the Oman desert
Abstract— The iron meteorite Shişr 043 is a single mass of 8267 g found in the south Oman desert 42 km NE of the Shişr village. It is the first iron identified among the >1400 individual meteorites
Characteristics of the Sahara as a meteorite recovery surface
We describe the geological, geomorphological, and paleoclimatic setting of the Sahara of North Africa in particular, focused on the main meteorite dense collection areas (DCA; Morocco, Algeria,
The new polymict eucrite Dar al Gani 983: Petrography, chemical composition, noble gas record, and evolution
Abstract— Mineralogical and chemical studies of Dar al Gani 983 show that this meteorite is a eucrite. Its texture is that of an impact breccia. It contains cumulate pyroxene and feldspar megacrysts,
Meteorites from the Lut Desert (Iran)
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
Description of a very dense meteorite collection area in western Atacama: Insight into the long‐term composition of the meteorite flux to Earth
We describe the geological, morphological, and climatic settings of two new meteorite collections from Atacama (Chile). The “El Médano collection” was recovered by systematic on‐foot search in El
Meteorite reconnaissance in Saudi Arabia
Meteorite searches in Saudi Arabia between 2008 and 2014 yielded 46 meteorites from the Yabrin area (23°N 49°E), 35 meteorites from the Rub' al‐Khali sand desert (19°–20°N, 48°–51°E), and 1 meteorite
The densest meteorite collection area in hot deserts: The San Juan meteorite field (Atacama Desert, Chile)
Abstract– We describe the geological, morphological, and climatic setting of the San Juan meteorite collection area in the Central Depression of the Atacama Desert (Chile). Our recovery activities

Abstract During the last 35 years, the number of meteorites available for study has increased by an order of magnitude (from around 2000 to nearly 30 000). The largest contribution has come from
Meteorites from the United Arab Emirates: Description, weathering, and terrestrial ages
We report on the first meteorite search campaign in the United Arab Emirates (UAE). The geology and proximity of our search region suggest that it is the north‐western extension of the Oman meteorite


Meteorites from the Sahara: Find locations, shock classification, degree of weathering and pairing
— The Sahara is an extraordinary area for recovering meteorites. Between 1989 and 1993, 471 meteorites were collected in Algeria and Libya. Studies of 465 samples have been done. In addition to the
Geophysical Studies of North African Cenozoic Volcanic Areas I: Haruj Assuad, Libya
This study is the first of a series in which a main concern will be to establish the Neogene absolute motion of the African Plate. A combined palaeomagnetic and K–Ar whole rock age dating study has
Meteorite flux on the Nullarbor Region, Australia
Abstract The Nullarbor Region of Australia is one of the most prolific sites for meteorite recoveries outside of Antarctica. Reported 14C terrestrial ages for chondritic meteorites from the Nullarbor

Abstract— Meteoritical Bulletin No. 85 lists information for 1376 newly classified meteorites, comprising 658 from Antarctica, 409 from Africa, 265 from Asia (262 of which are from Oman), 31 from
Ancient Meteorite Finds and the Earth's Surface Environment
Abstract The flux of meteorites to the Earth over the last 50,000 yr has remained approximately constant. Most meteorites that fall in temperate or tropical areas are destroyed on a time scale which
