Ka ʻike ʻana i ka nani hoʻohiwahiwa o nā kristal spinel: kahi nānā hohonu i ko lākou mau hiʻohiʻona honua

ʻO nā kristal Spinel kahi ʻano mineral i ʻike ʻia no ko lākou nani kupanaha a me nā ʻano kala like ʻole. Hiki ke loaʻa kēia mau kristal i nā aka o ka ʻulaʻula, ʻulaʻula, poni, uliuli, ʻōmaʻomaʻo, a me ka ʻeleʻele, a ua mahalo ʻia no ko lākou ʻano crystalline kūʻokoʻa a me nā hiʻohiʻona nani. Ma kēia moʻomanaʻo moʻomanaʻo, e nānā mākou i nā hiʻohiʻona geological o nā kristal spinel, e ʻimi ana i ko lākou kumu, aʻo, a me na waiwai kino.
ʻO nā kristal spinel no ka hui spinel o nā minela, aia nā ʻano silicates me ke ʻano kemika MgAl2O4. Uaʻikeʻia kēia mau mineral no ko lākou kū'ē kiʻekiʻe i ka wela a me kaʻaʻahu, a hoʻohana pinepineʻia e like me nā abrasives a me nā pōhaku. Loaʻa pinepine ʻia nā kristal spinel i loko o nā pōhaku metamorphic, e like me ke kinikini a me ka serpentinite, a hiki ke loaʻa i loko o nā pōhaku ultramafic metamorphosed a me nā pōhaku igneous mafic.
ʻO ka hoʻokumu ʻana i nā kristal spinel he kaʻina hana paʻakikī e pili ana i ka hoʻololi ʻana o nā minela i loaʻa ma lalo o nā kaomi kiʻekiʻe a me nā mahana. Hiki ke hana ʻia kēia kaʻina hana, i kapa ʻia he metamorphism, i loko o ka ʻōpala o ka honua or ʻaʻahu, a pili maʻamau me ka hana tectonic a me ka komo ʻana o ka pelemaka. Ma muli o ka metamorphism, hiki ke hoʻohui ʻia nā kristal spinel ma ke ʻano he hoʻohui ʻia i loko o nā minela ʻē aʻe, a i ʻole hiki ke hoʻokaʻawale kūʻokoʻa e like me nā kristal discrete.
Ma ke ʻano o nā waiwai kino, ʻike ʻia nā kristal spinel no ko lākou kiʻekiʻe kikoʻī kikoʻī, paʻakikī, a me ka helu refractive. ʻO kēia mau waiwai, i hui pū ʻia me ko lākou mau waihoʻoluʻu a me nā hiʻohiʻona nani, e hana i nā kristal spinel i mahalo nui ʻia e like me nā pōhaku makamae. ʻO ka ʻoiaʻiʻo, ua hoʻohana ʻia nā kristal spinel e like me nā pōhaku makamae no nā kenekulia, a ua mahalo ʻia e nā ʻohana aliʻi a me nā ʻohi. ʻO kekahi o nā kristal spinel kaulana loa ma ka honua, ʻo ia ka "Black Prince's Ruby," he spinel nui a ʻulaʻula i hoʻonoho ʻia ma ka Imperial State Crown o ʻEnelani, a me ka "Timur Ruby," he spinel nui a ʻulaʻula i ʻāpana o ka. na Leialii Beritania.
I ka hopena, ʻo nā kristal spinel kahi ʻano minerala hoihoi i ʻike ʻia no ko lākou nani hoʻohiwahiwa a me nā hiʻohiʻona kūlohelohe. Mai ko lākou mau kala like ʻole a hiki i ko lākou mau waiwai kino, ua hopu kēia mau kristal i ka manaʻo o ka poʻe geologists a me nā mea hoihoi pōhaku. Inā he kanaka kālaihonua kau ʻoe a i ʻole he mahalo wale ʻoe i nā waiwai o ka honua, ʻo nā kristal spinel e hoʻohauʻoli a hauʻoli.
