RM1886   Meteorite of Chelyabinsk - Ordinary chondrite (LL5)

Chelyabinsk, Chelyabinsk Oblast, Russia

This is one of the fragments of the meteorite of Chelyabinsk. At 9:22 a.m. (local time) on February 15, 2013, a bright fireball was seen by numerous residents in parts of the Kurgan, Tyumen, Ekaterinburg and Chelyabinsk cities. This superbolide meteor descended at over 55,000 Km/h over the Ural Mountains, exploding at an altitude of 25-30 km.
These fragments are ordinary chondrite meteorites and contain 10% iron. The Chelyabinsk meteorite was later determined to come from the LL chondrite group (LL5). The majority of the stones are composed of a light-colored lithology with a typical chondritic texture. Chondrules (~63%) are readily delineated and set within a fragmental matrix. The chondrule glass is devitrified. The main phases are olivine and orthopyroxene. Rare grains of augite and clinobronzite are present. In this sample we can observe perfectly chondrules and fusion crust. Very representative and good sized sample (5.08 grams / 0.18 oz).

RM1895   Native iron in basalt

Khungtukun Massif, Taimyr Peninsula, Khatanga, Taymyrskiy Autonomous Okru, Krasnoyarsk Krai, Russia

Slab of native iron in mafic matrix. Specimen is tilted so reflections of sunlight make iron stand out from matrix. This iron could be refered to kamacite variety (content in Ni). It is accompanied by fayalite-forsterite and labradorite. Probably some cohenite is present in the sample. Analisys will be send to the buyer.

RM1836   Graphite

Radigara, Ratnapura, Sabaragamuwa, Sri Lanka

A good sized sample of graphite showing parallel aggregates of crystals. The lusters is spectacular, with that black "flywing" tone. One of the faces of the sample has some scratches we wanted to preserve and that show the piece was used for some scientific experiments. According to the owner of the piece, the sample was collected near the end of XIXth, around 1890. Confirm that Radigara is the origin is difficult, but it does belong to the Ratnapura mining district. The metallic luster, bright and pure, has a greasy feeling, as expected. This mining area is today a place famous for its gems, but we must not forget that once it was also important for native graphite. Currently obtaining these specimens is very rare, since sapphires and rubies are obviously more valuable for miners.


Size: 8 x 5 x 2.5 cm.

Mustafa Kemal Pascha Mine, Kestelek, Mustafa Kemalpafla, Bursa, Marmara, Turkey

Rich radial aggregates of hydroboracite crystals, colorless to white, with a very intense adamatin luster. SEM-EDS analysis show the absence of sodium, with magnesium and calcium predominant. Boron can not be observed with this spectroscopic technique. Turkey is one of the largest producers of borates in the world, with reserves that surpass those of other countries such as USA, China or Russia. The borate works are located a few miles SE of Kestelek. Spectacular fluorescence yellow for hydroboracite and orange for probertite.
