On Offer: 17.89g Sari i ek HED achondrite howardite meteorite

Class: Howardite

Witnessed Fall: Turkey, 2015

Description: An amazing 17.89 gram specimen of the 2015 Sari i ek HED howardite witnessed fall. This specimen was purchased from Greg Hupe several years ago, who bought it onsite in Turkey shortly after the fall. The entire specimen is completely covered with glassy black fusion crust. There have not been many HED witnessed falls in recent history, and even fewer that were howardites. A pristine specimen with translucent glassy fusion crust that has to bee seen in person to be truly appreciated.

The HED Meteorites: The HED meteorite group is so named for the three types of meteorites that comprise the group; Howardite, Eucrite and Diogenite. The Eucrite and Diogenite are distinct meteorites, while the Howardite is a mix of the Eucrite and Diogenite lithologies. The HEDs are differentiated achondritic meteorites previously thought to originate from Vesta, but now leading researchers are starting to think they originated from a Vesta-like asteroid (not Vesta itself) that was destroyed long ago. This is because we also find iron meteorites with similar isotopic genetics as the HED, leading researchers to conclude the HED meteorites come from a large Vestan-like body that was in a large enough collision to also liberate pat or all of its metal core.

Sari i ek 38 54.10 N, 40 36.01 E

Bingol, Turkey

Confirmed fall: 2015 Sept 2

Classification: HED achondrite (Howardite)

History: (O. nsalan, UIst; P. Jenniskens, SETI): A bright bolide was seen and heard in Bingol province, Turkey, and recorded on several video security cameras on 2015 Sept 2 at 20:10:30 UT. Shortly after the fireball, small meteorites were heard raining down on houses in the village of Saricicek. The next morning, people found pea-sized meteorites on the street and in yards. Tu e zduman of the police in Bing l supplied the first video data from traffic cameras in Bitlis, a neighboring city. Dedicated searches were done by Iskender Demirkol, Ibrahim Yasin Erdo an, Ayd n S kr Beng and Vedat Avci of Bingol University. The 27 g meteorite analyzed here was found by Mehmet Nezir Erg n of Sari i ek the morning of September 4.

Physical characteristics: (O. nsalan, UIst; P. Jenniskens, SETI): The meteorite is fully crusted and has a shiny, light-brown crust. The shape is irregular and rounded, indicative of high altitude fragmentation and ongoing breakup until just before deceleration.

Petrography: (M. Zolensky, JSC): Petrographically heterogeneous rock consisting of lithic and mineral clasts in a fine-grained matrix of crushed material. The matrix consists of high-Ca pyroxene (probably clinopyroxene) from the eucritic component, low-Ca pyroxene (probably orthopyroxene) from the diogenitic component, plagioclase, silica, kamacite, troilite, chromite, ilmenite and rare olivine. Clino- and orthopyroxene are present in approximately equal amounts. Single mineral grains and clasts of orthopyroxene, clinopyroxene, plagioclase, and rare olivine, all to a maximum size of 1 mm. Crystals of clinopyroxene frequently contain exsolution lamellae of orthopyroxene, in which both phases can contain oriented chromite inclusions. Three types of rock clasts are distinguished: (1) Clasts consisting plagioclase and silica, the former containing inclusions of chromite and ilmenite, and the latter containing blebs of troilite; (2) clasts consisting of an intergrowth of plagioclase and silica, with both phases hosting large blebs of troilite; (3) ophitic to subophitic basalt clasts consisting of an intergrowth of plagioclase laths and zoned clinopyroxene, in some cases with troilite blebs situated along the boundaries of the plagioclase crystal laths. Eucritic material appears to be more abundant than the diogenitic component. Single mineral grains and clasts show different degrees of shock deformation, including irregular fractures and folded pyroxene lamellae, and a significant fraction of the finest grained matrix appears to be poorly crystalline. Near the fusion crust melted troilite has been injected into cracks in silicates.

Geochemistry: (M. Zolensky, JSC): The matrix consists of high-Ca pyroxene (probably clinopyroxene) Fs 50 18Wo 26 20, FeO/MnO= 21.0-45.9, N=29, from the eucritic component, low-Ca pyroxene (probably orthopyroxene) with Fs 28 6Wo 2 1, FeO/MnO = 31.1-36.7, n=23 from the diogenitic component and Fs 53 19Wo 3 3; plagioclase, An 83.5-89.6Or 0.2-4.0; olivine, Fa 18-21, FeO/MnO= 30.1-43.1, average Fa 80, PMD=1.6%, N=4. Single mineral grains and clasts: orthopyroxene, Fs 22-70Wo 1-2; clinopyroxene, Fs 28-60Wo 6-36, some compositionally zoned; plagioclase, An 85.5-89.6Or 0.2-0.6; olivine, Fa 21. Basaltic clasts: plagioclase, An 85Or 1; clinopyroxene, Fs 33-55Wo 6-12.
