Title: Die mineralogische Zusammensetzung des Meteoriten von Kiel
Authors: D. Ackermand, P. Raase

The mineralogical composition of the meteorite of Kiel was analysed microscopically and with the electron microprobe. The meteorite consists mainly of chondrules, which are recrystallised to some extend and which are embedded in a recrystallised ground-mass. The chondrite contains 55 Vol.-% olivine of composition (Fa24,2Fo75,3Te0,5), 28 Vol.-% orthopyroxene (Fs21,4 En76,8Wo1,8), 9 Vol.-% plagioclase (An9,4 Ab85,1 Or5,5), 4,5 Vol.-% troilite and 2,5 Vol.-% Fe-Ni-metal grains, consisting of kamazite, zonal taenite and plessite; furthermore the chondrite contains chromite, whitlockite and a very small amount of ilmenite, native copper, chalcopyrrhotine and valeriite.
