Writeup from MB 84:


Tsukushigaoka, Kita-ku, Kobe, Japan

Fell 1999 September 26, 20:21 h (local time)

Carbonaceous chondrite (CK4)

A fireball was widely observed in the western prefectures of Kobe City.  Shortly after a detonation was heard, one stone was recovered in Tsukushigaoka, Kita-ku, in the northern part of the city.  It broke into 20 pieces after penetrating the roof of the house of Ryoichi Hirata; much of the material ended up on a bed.  The total mass is 136 g, with the largest pieces weighing 64.9, 32.9, and 13.6 g.  Classification and mineralogy (N. Nakamura and K. Tomeoka, UKobe ; H. Kojima, NIPR):  olivine, Fa31.4 (range Fa30.0–32.0, N = 5 4); pyroxene, Fs25.8 (range Fs24.7–26.6, N = 14); plagioclase, An57.2 (range An50.2–67.3); contains magnetite with 0.5–2.1 wt% Al, 3.2–5.2 wt% Cr; chondrules are distinct, 0.2 to 2 mm in diameter; a few white inclusion-like objects appear on the broken surface of the largest stone.  Specimens: type specimen, 0.9 g (from which two thin sections were produced), NIPR; two pieces, 17 g, on loan from finder to N. Nakamura, UKobe, for consortium studies; remainder with finder.
