0.11g MUKUNDPURA Meteorite fragment I Carbonaceous Chondrite CM2 I Witnessed Fall India
Top Meteorite
- $ 110.00
On Offer: 0.11g Mukundpura Carbonaceous Chondrite meteorite fragment from the June 6th, 2017 fall in Rajasthan, India. This Mukundpura specimen has impeccable provenance.
Type: CM2 Carbonaceous Chondrite
Description: This is a fresh 0.11 gram CM2 Mukundpura fragment. The interior is dark black with an abundance of small white spots.
Fall Coordinates: 26º52’52.5’’N, 75º39’53.7’’E
CM2: The "C" designates carbonaceous and the "M" indicates "Mighei-like". The numeral "2" after the CM indicates the level of aqueous alteration. This meteorite was *likely altered by water on its parent asteroid and contains significant amounts of extraterrestrial hydrous minerals.
*Some researchers hypothesize the aqueous alteration occurred in the protoplanetary disc well before it was accreted into its parent asteroid.
Additional Details: Acquired in 2017 immediately after it was recovered by Mr. Banshi Ram. This meteorite was originally given the name "Jaipur" prior to its official name of Mukundpura as published in the Meteoritical Bulletin. This is one of the more difficult to acquire CM2 witnessed falls with very little material available to the collectors and researchers. As far as we know, these are the only Mukundpura specimens currently available for sale.
History: "A meteorite weighing approximately 2 kg fell in Mukundpura village at 05:15 hrs on June 6, 2017, on sandy soil in the agricultural field of Mr. Banshi Ram. The impact formed a nearly circular crater of ~40 cm diameter with a depth of 15 cm. Upon impact, the stone shattered into several large pieces and multiple gram and subgram-sized fragments. Mr. Banshi Ram observed a bright red-yellow colored burning fragment fall with a thundering sound about 100 m away from his house."
What you get: 0.11g Mukundpura Carbonaceous Chondrite meteorite specimen as shown, membrane storage/display box, & signed Certificate of Authenticity.

Writeup from MB 107: Mukundpura 26º52’52.5’’N, 75º39’53.7’’E Rajasthan, India Fall: June 6, 2017 Classification: Carbonaceous chondrite (CM2) History: A meteorite weighing approximately 2 kg fell in Mukundpura village at 05:15 hrs on June 6, 2017, on sandy soil in the agricultural field of Mr. Banshi Ram. The impact formed a nearly circular crater of ~40 cm diameter with a depth of 15 cm. Upon impact, the stone shattered into several large pieces and multiple gram and subgram-sized fragments. Mr. Banshi Ram observed a bright red-yellow colored burning fragment fall with a thundering sound about 100 m away from his house. They informed the nearby Bhankrota police station, where the large pieces were deposited. The fall of meteorite in the Mukundpura Village was reported in the media. Dr. Anil D. Shukla and Dr. D. Ray visited the fall site two days after the fall and acquired some fragments from the local villagers, with the help of police. Physical characteristics: The meteorite is covered in well-developed matte fusion crust with a few broad regmaglypts. The interior of the stone is dark black with an abundance of small white spots. There are various clasts (angular to rounded and up to 4 cm across) embedded in the dark colored matrix. Petrography: The modal abundances avearged from three thick sections include chondrule (~15%), matrix (~70%), refractory inclusions (~2%), carbonates (~7%), Fe-Ni metal (~2%), and sulfides (~4%). Matrix is dominated by serpentine with lesser tochilinite. Geochemistry: The Fa content of granular porphyritic olivine chondrule is uniform and highly forsteritic (Fa<1, SD=0.13, n=16). The Fa content of barred olivine chondrule is ferroan and composition ranges Fa32-33(SD=0.06, n=11). The Cr2O3 of granular and barred olivine is almost indistinguishable and ranges 0.36 to 0.61 wt%. The Fe/Mn ratios of type IIA chondrule follow the similar trend to the CO chondrites. The bulk chemical composition of Mukundpura chondrite was analysed using XRF and Q-ICPMS. The major oxides of Mukundpura show a very good match with Murchison and Paris CM carbonaceous chondrite. Following XRF data in wt%: SiO2 29.5, TiO2 0.13, Al2O3 1.3, Fe2O3 32.4, MnO 0.22, MgO 17.4, CaO 1.7, Na2O 0.59, K2O 0.05, and P2O5 0.21. Classification: CM2 chondrite fall. Specimens: Type specimen 30.5 g at PRL. Main mass ~2000 g with GSI (Based on the report on GSI web portal). |
