Writeup from MB 102:

Dongyang        29.2753°N, 120.2363°E

Zhejiang, China

Fell: July 2002

Classification: Ordinary chondrite (H5)

History: During a night in July 2002, Mr. Xu Yiping heard an explosion. Several days later, he noticed that his roof was leaking and a black stone on the floor.

Physical characteristics: Single 230 g fusion-crusted, blocky stone, with chipped corners.

Petrography: Olivine, low-Ca pyroxene, kamacite, taenite and troilite are major phases. Minor phases include high-Ca pyroxene, plagioclase, chromite and apatite. Some chondrules with an indistinct edge can be recognized. Plagioclase grains range from 2 to 50 μm in size. Olivine was fractured; shock-induced veins, melt pockets and plagioclase-chromite assemblage are present in the matrix.

Geochemistry: The chemical compositions of olivine (Fa18.4) and low-Ca pyroxene (Fs16.3) are uniform.
