LINK<\/strong><\/a><\/p>\n“Meteorite searches in Saudi Arabia between 2008 and 2014 yielded 46 meteorites from the Yabrin area (23\u00b0N 49\u00b0E), 35 meteorites from the Rub’ al\u2010Khali sand desert (19\u00b0\u201320\u00b0N, 48\u00b0\u201351\u00b0E), and 1 meteorite from Al Haddar. No meteorites were found near Hafar al Batin (29\u00b0N 45\u00b0E). The 82 new meteorites represent ~57 falls comprising 43 ordinary chondrites, 4 carbonaceous chondrites, 2 enstatite chondrites, 3 ureilites, 3 eucrites, 1 acapulcoite, and 1 lunar meteorite. The median of 31 14C terrestrial ages is 6.2 ka, significantly younger than the Oman population (19.5 ka, n = 128). A further assessment of terrestrial 14C contamination is advised by a 11\u201315 ka 14C terrestrial age of heavily weathered meteorite Khawr al Fazra 014, geology indicating a terrestrial age >100 ka. Find densities of 0.4\u20132.8 km\u22122 for Yabrin and the western Rub\u2019 al\u2010Khali are similar to ~0.5 km\u22122 observed in Oman. Higher find densities of ~135 km\u22122 (29 km\u22122 for masses >10 g) exist on small Pleistocene outcrops in blowouts in the south\u2010central Rub\u2019 al\u2010Khali: 21 unpaired meteorites (four >10 g) were found in 11 blowouts with a combined area of 0.14 km2. The Rub\u2019 al\u2010Khali meteorites show a relatively high degree of weathering (median W 3.6; 2.5 for Yabrin), low median mass (4.3\/138 g), and a high H\/L ratio (2.3\/1.1). The high density of small meteorites is explained by prolonged sand protection and recent deflation. The high meteorite density and relatively high proportion of rare meteorite types render the Rub\u2019 al\u2010Khali blowouts an interesting target for future exploration. ”<\/p>\n","protected":false},"excerpt":{"rendered":"
