Writeup from MB 106:

Magwe        ~20°11’N, ~94°58’E

Magwe, Burma

Find, doubtful fall: 2004 June 18

Classification: Ordinary chondrite (L5)

History: (R. Bartoschewitz, Bart, Wang Jun) On 2004 June 18 at 12:30 pm local time, a fireball was witnessed from Mandalay moving in a southwesterly direction. At an unknown date, a 1.5 kg stone was discovered in the northeastern area of Magwe, some 230 km to the SW. The stone was sold by the finder to Wang Jun in 2014.

Physical characteristics: (R. Bartoschewitz, Bart) One 1.5 kg stone, covered by >80% fusion crust with some rusty specks. Cut face presents fresh metal specks in gray-brown matrix.

Petrography: (R. Bartoschewitz, Bart) recrystallized matrix of olivine, pyroxene and secondary feldspar bear various types (BO, PO, POP, RP) of poorly developed chondrules (0.5 to 1.1 mm, av. 0.7 mm), metal, troilite and chromite.

Geochemistry: Mineral compositions and geochemistry: (R. Bartoschewitz, Bart, P. Appel/B. Mader Kiel) olivine: Fa24.6 (Fa23.9-25.7, n=24); pyroxene: Fs20.7Wo1.6 (Fs20.0-22.5Wo1.2-1.8, n=15); feldspar: An8Or9 (An6-10Or4-19; n=3); merrillite; chromite: CRAL 87, FMM 81. Kamacite Ni 5.5 (2.7 - 6.1, n=14), Co 0.97; taenite 41.5 (36-47, n=5) (all in wt.%); tetrataenite. Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 4.89. Cosmogenic radionuclides: (M. Laubenstein, LNGS) 22Na <57, 60Co <8.7, 44Ti 2±1, 26Al 54.6±4.3 (all in dpm/kg).

Classification: (R. Bartoschewitz, Bart) L chondrite (L5, S4, W0/1)

Specimens: main mass of about 1.45 kg Wang Jun; type specimen 20.1 g Kiel.
