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.
In terms of physical properties, spinel crystals are known for their high specific gravity, paakiki, and refractive index. These properties, combined with their vibrant colors and lustrous appearance, make spinel crystals highly prized as gemstones. In fact, spinel crystals have been used as gemstones for centuries, and have been prized by royals and collectors alike. Some of the most famous spinel crystals in the world include the “Black Prince’s Ruby,” a large, red spinel that is set in the Imperial State Crown of England, and the “Timur Ruby,” a large, pink spinel that is part of the British Crown Jewels.
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.
