A mesosiderite with a fascinating story surrounding its recovery. It may have been known for a long time but its formal recognition as a meteorite occurred approximately in 1956. It was then that H. H. Nininger realized that it was meteoritic and not low-grade iron ore of some type as many individuals in the Philippines were reporting. It actually took 3 1/2 years for Nininger to acquire the 1955-pound stone from the jungle and get it to Sedona, Arizona. But what a special meteorite it is. It has large metal nodules besides the normal mixture of metal and mineral common to mesosiderites. Some small pieces are nearly metal free while others are nearly solid metal.
Bondoc is a mesosiderite found on the Bondoc Peninsula, Philippines, and obtained by H.H. Nininger in 1962. Over 850 kg of the meteorite was recovered, 550 kg of which is now housed at the Center for Meteorite Studies.
Bondoc is an extremely unusual, heterogeneous, brecciated meteorite consisting of a silicate matrix of cumulate pyroxene with interstitial plagioclase and clasts of pyroxenite and dunite, together with metal nodules and minor troilite.
Rounded nodules of metal, up to tens of
centimeters
across, occur within the predominantly silicate matrix. The metal consists primarily of a polycrystalline aggregate of 3 to 4 mm sized equant grains of kamacite. Minor taenite and schreibersite border the kamacite. Especially intriguing is the presence of oxide-silicate-phosphate inclusions within the nodules, consisting of plagioclase, tridymite, whitlockite, chromite and pyroxene.
