Mainzer Meteorit, Mainz, Rheinland-Pfalz, Deutschland


Ordinary chondrite, veined (L6)
Find, 1852 ; 1.70 kg

A stone was plowed up just outside the Mainz town wall. Early chemical analysis detected sufficient olivine and Fe-Ni metal to indicate its meteoritic nature (chondritic). While the meteorite is distinctly weathered, olivine (Fa24), pyroxene (Fs20), and total iron content require a more contemporary classification as an ordinary L6 chondrite. Plagioclase is albitic with a moderately high potassium component. Enough unweathered Fe-Ni metal remains to allow the identification of kamacite, taenite, and even small amounts of tetrataenite. The early chemical analysis (1857) also suggested the highly probable presence of troilite and possible phosphates, but these findings need confirmation. K-Ar dating provides an ancient age (~4.3 Ga). The terrestrial age (~50 Ma) is quite high for an ordinary chondrite.

Eleven ordinary L chondrites have been recovered in Germany, but Mainz meteorite is one of only two finds. In the nineteenth century, the mass was subdivided into numerous small pieces with the largest fragment today being housed in Calcutta. A few small pieces still remain in Germany (Tübingen, Berlin and Mainz).
