Type: Ordinary chondrite (H4; S3)
Fall: 26 May 1893
Weight: 14 kg
During the afternoon a meteoritic stone fell and broke into two pieces. The largest piece (~14 kg) dug a hole ~90 cm deep. Mean composition of the olivine (Fa18.6) is characteristic of the H-chondrite geochemical group. Mineralogically, the meteorite consists primarily of olivine and pyroxene accompanied by troilite and Fe-Ni metal. Accessory chromite, isocubanite, chlorapatite and merrillite are also present. The phosphates have been critical for chronological studies. An absolute age (I-Xe) for the putative parent body of 4.569 Ga and a cosmic ray exposure age of 45.9 Ma for the preterrestrial meteoroid have been reported.
