ʻO Hibonite, mai Madagascar

wikiō

ʻO ka Hibonite ((Ca, Ce) (Al, Ti, Mg) 12O19) he mineral mineralʻeleʻele me ka mea paʻakikī o 7.5-8.0 a me ka hoʻonā aniani tioki. He mea maʻamau, akā, aia i loaʻa i nā pōhaku kūpona ma ka kiʻekiʻeʻo Madagascar. ʻO kekahi mau meaʻai i nā meteorites mua o ka hibonite. ʻO ka Hibonite kekahi meaʻokoʻa maʻamau ma ka Ca-Al-waiwai waiwai (CAI) i loaʻa i kekahi mau meteor. Hoʻopili pili loaʻo Hibonite i ka hibonite-Fe (IM, 2009-027, ((Fe, Mg) Al12O19)) he kolaki hoʻololiʻia mai ka Allende meteorite.

He inoa nui loa, i kapaʻia ma hope o Paul Hibon, he mea prospector ma Madagascar, nāna iʻike i ka mineral ma June 1953. Ua hoʻouna akuʻo ia i kahi'āpana me kekahi mau mea helu iā Jean Behier no ka ninaninauʻana i kēlā makahiki. Uaʻikeʻo Behier i kahi mineral hou a hāʻawiʻia i ka inoaʻo "hibonite". Ua hoʻokuʻuʻo ia i ke kiʻi i C. Guillemin, Labratoire de Minéralogie de la Sorbonne, ma Paris, Farani e nānā houʻia. ʻO ia ka hopena o ka mineral hou e Curien et al (1956).

ʻO Hibonite mai'Esiva,'Apanaʻo Fort Dauphin, Tuléar, Madagascar
'Oleʻele, mau kulu paʻakikī e hoʻomahaʻia ma ka metamorphosed kuakone ka waiwai nui i ka helu helu palgioclase. ʻO nā hoa pili i loko o ka māmā, he corundum, spinel a me thorianite. Hōʻikeʻia ma ka 1956. ʻAʻole e pilikia me ka Hibbenite. Ua kapaʻiaʻo Hibonite ma hope o P. Hibon, nāna iʻike i ka mineral.
