Ordinary chondrite (L6)
Find, 1963; 393 g

A complete meteoric stone was found by G. Eisenhower while plowing his "Bonnie Doon" property. Inspections reveal indistinct chondrules within an equilibrated matrix. Compositionally, equilibrated olivine (Fa25.9) and low Ca-orthopyroxene (Fs21.4) are characteristic of the L-chondrite geochemical group. Mineralogically, the meteorite consists primarily of dominant olivine plus pyroxene accompanied by minor troilite and Fe-Ni metal. Accessory chromite, copper, ilmenite, and minor sulfides have also been reported. Very strong shocks have converted most of the plagioclase to maskelynite. More interestingly, ringwoodite and majorite, high pressure polymorphs of olivine and pyroxene, respectively, are indicative of a very high pressure (collisional) event.

The main mass is at the Australian Museum in Sydney.
