ataata

Ko te Hibonite ((Ca, Ce) (Al, Ti, Mg) 12O19) he kohuke pango pango me te pakeke o te 7.5-8.0 me te hanganga karaihe hexagonal. He waimarie, engari kei roto i nga toka o te toka teitei i runga i Madagascar. Ko etahi o nga kaimoana i roto i nga meteorite tawhito ko te hibonite. Ko te Hibonite ano he kohuke noa i roto i te Ca-Al-rich inclusions (CAI) kitea i roto i etahi meteorites chondritic. Ko te Hibonite e tata ana ki te hibonite-Fe (IM, 2009-027, ((Fe, Mg) Al12O19)) he kohuke rereke mai i te Meteorite Allende.

He mea tino nui rawa te ingoa, i huaina i muri i a Paul Hibon, he kaipoihoki Pakeha i Madagascar, nana i kitea te kohuke i te Pipiri 1953. I tonoa e ia he pepa ki etahi atu tauira ki a Jean Behier mo te whakamatau i taua tau. I mohio a Behier he kohinga hou me te hoatu i te ingoa mahi "hibonite". I tukuna e ia te tauira ki a C. Guillemin, Labratoire de Minéralogie de la Sorbonne, i Paris, Parani kia arotakengia ano. I puta mai he whakaahuatanga mo te kohuke hou na Curien et al (1956).
