Burlatskoe 44°59.24’N, 43°36.24’E Stavropol’skiy kray, Russia Find: 1995 Classification: Ordinary chondrite (H3-5) History: The meteorite was found by Ivan Ivanovich Poljulja in his vegetable garden during cultivation in 1995. The meteorite was excavated from a shallow depth. Physical characteristics: A single brown stone of 6.24 kg of total weight with polyhedral shape. The stone is partly covered by weathered fusion crust. Petrography: The meteorite is composed of poorly definite angular clasts of 0.5-1.5 cm in size surrounded by fragmented material. The clasts have a brecciated texture and consist of chondrules, chondrule fragments and mineral grains in a fine-grained clastic matrix. Average chondrule apparent diameter 400 µm. The main minerals are olivine and pyroxene. Other minerals: feldspathic glass, feldspar, metal FeNi, troilite. Accessory minerals: merrillite, chromite. Veinlets of Fe hydroxides are widely developed along grain boundaries. Geochemistry: Mineral compositions and geochemisty: (C. A. Lorenz, Vernad; T. V. Kryachko, Technograd, Moscow, Russia): both the clasts and surrounding material are composed a mixture of two compositionally different types of chondrules and mineral grains: 1) dominant equilibrated material: olivine Fa17.9±0.4 (N=32); pyroxene is Fs15.9±0.3Wo1.5±0.2 (N=25); 2) minor unequilibrated chondrules and mineral grains: olivine Fa17.9±10.6 (N=61), Fa PMD 49.3%; pyroxene Fs9.1±7.3Wo1.0±0.9 (N=20). Classification: Ordinary chondrite breccia composed of dominant H5 material and minor H3 material (H3-5), moderately weathered (W2). Specimens: Type specimen (three samples of 1097 g, 19.6 g, 3.0 g) and thin polished section are on deposit at Vernad. The main mass is in DMUH. | ||||||||||||||||||||||||||||||||||||||
