Sariçiçek Meteorite 17.897g - Pristine HED Howardite Achondrite Fall 2015

Top Meteorite

  • $ 1,800.00


 

On Offer: 17.897g Sariçiçek Achondrite HED Howardite meteorite from the Fall in Turkey on September 2, 2015.
Type: Howardite
Parent Body: Vesta or Vestoid

Description: 

17.897 gram absolutely exquisite perfectly crusted individual of Sariçiçek collected by G. Hupe from local hunters in Turkey and held in his private collection until very recently. This specimen is perhaps the best example of a fresh achondrite that I have ever seen.

A perfectly intact specimen with the fine glassy transparent flow lines, unique to the fusion crust of achondritic falls, is a rare find for even a seasoned collector. The meteorite must land in a "soft" enough place to keep the stone completely in tact and undamaged. Then it must be recovered quickly enough that no weathering occurs. Finally, the people doing all of this must have been thoughtful enough to have kept the incredibly fine and delicate glass rivulets of the flow lines from getting damaged. A small miracle really. There is a little bit of what looks like a fine powdery dirt on a few areas of the meteorite, landing in this soft dirt may have what allowed it to remain intact and undamaged.

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 meteorites with distinct chemistries, while the Howardite is a mix of the Eucrite and Diogenite material. The HEDs are differentiated achondritic meteorites, thought to originate from the large differentiated asteroid 4 Vesta. The Vesta parent body origin for the HED clan is considered to have been conclusively established for many years. However, some leading researchers are now starting to suspect they originated from a larger Vesta-like asteroid that was blown apart long ago. This is because we also find a class of iron meteorites with the exact isotopic genetics as the HED clan, leading some researchers to conclude the HED meteorites come from a larger Vestan-like body that was in a cataclysmic collision that liberated part or all of its metal core. This hypothesis does not rule out the possibility that all of the material including Vesta and the Vestoids and the HED meteorites were once part of a much larger dwarf planet prior to this collision.

Sariçiçek        38°54.10’N, 40°36.01’E

Bingol, Turkey

Confirmed fall: 2015 Sept 2

Classification: HED achondrite (Howardite)

History: (O. Ünsalan, 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. Tuğçe Özduman of the police in Bingöl supplied the first video data from traffic cameras in Bitlis, a neighboring city. Dedicated searches were done by Iskender Demirkol, Ibrahim Yasin Erdoğan, Aydın Sükrü Bengü and Vedat Avci of Bingol University. The 27 g meteorite analyzed here was found by Mehmet Nezir Ergün of Sariçiçek the morning of September 4.

Physical characteristics: (O. Ünsalan, 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) Fs50±18Wo26±20, FeO/MnO= 21.0-45.9, N=29, from the eucritic component, low-Ca pyroxene (probably orthopyroxene) with Fs28±6Wo2±1, FeO/MnO = 31.1-36.7, n=23 from the diogenitic component and Fs53±19Wo3±3; plagioclase, An83.5-89.6Or0.2-4.0; olivine, Fa18-21, FeO/MnO= 30.1-43.1, average Fa80, PMD=1.6%, N=4. Single mineral grains and clasts: orthopyroxene, Fs22-70Wo1-2; clinopyroxene, Fs28-60Wo6-36, some compositionally zoned; plagioclase, An85.5-89.6Or0.2-0.6; olivine, Fa21. Basaltic clasts: plagioclase, An85Or1; clinopyroxene, Fs33-55Wo6-12.

Classification (M. Zolensky, JSC): Howardite

Specimens: 27 g sample #SC24 at UIst. 27 g sample #SC12, described above, with P. Jenniskens. A list of other finds is maintained at http://turk-met.net/saricicek-meteoritleri/. Small meteorites are at the UIst, Department of Physics (Ozan Ünsulan). A small collection of meteorites is at Bingol University (Iskender Demirkol).
