Welina mai i ka honua hoihoi o prehnite! Inā he kanaka hulihonua ʻoe, e ʻike ʻoe ʻo ka prehnite he mineral silicate calcium aluminika i loaʻa pinepine i nā pōhaku metamorphic. Akā ʻoi aku ka nui o kēia mineral ma mua o ka ʻike.

Ua ʻike mua ʻia ʻo Prehnite i ke kenekulia 18 e ka mea hoʻomanaʻo Dutch, ʻo Hendrik von Prehn. Ua kapa ʻia ʻo ia ma hope ona a ua kapa pinepine ʻia ʻo ia ʻo "ka pōhaku o ka wānana" no ka mea ua manaʻo ʻia he mau mea pohihihi e hiki ke kōkua i ka poʻe e ʻike i ka wā e hiki mai ana. ʻOiai ʻaʻole hiki iā mākou ke hōʻoia i kēia mau ʻōlelo, hiki iā mākou ke hōʻoia i ka prehnite he mineral nani a hoihoi nui i hāʻawi ʻia i ka honua o ka geology.

ʻO kekahi o nā mea hoihoi loa e pili ana i ka prehnite ʻo ia kona haku melemele. Hoʻokumu ʻia ia me ka calcium, aluminika, a me ka silicate, ka mea e hāʻawi iā ia i kahi hoʻonohonoho kūʻokoʻa o nā waiwai e waiwai ai ka poʻe kālaihonua. No ka laʻana, hoʻohana pinepine ʻia ka prehnite ma ke ʻano he mineral kuhikuhi no ka mea hiki iā ia ke kōkua i ka poʻe geologists e ʻike i ke ʻano o nā minerale ʻē aʻe ma kahi wahi. No ka mea, loaʻa pinepine ka prehnite ma kahi kokoke i nā minerale ʻē aʻe, e like me quartz, feldspar, a me ka mika.

He mea nui nō hoʻi ka prehnite no ka mea hiki iā ia ke kōkua i ka poʻe kālaihonua e hoʻomaopopo i ke kālaihonua o kahi wahi. Ke loaʻa ka prehnite i loko o nā pōhaku metamorphic, hiki iā ia ke hōʻike i nā loli nui o ka pōhaku ma muli o ka wela a me ke kaomi. He mea waiwai kēia ʻike no ka mea hiki iā ia ke kōkua i ka poʻe kālaihonua e hoʻomaopopo i ka mōʻaukala o kahi wahi a me ke ʻano o ka loli ʻana o ka manawa.

Ma waho aʻe o kāna waiwai ʻepekema, ʻo ka prehnite kekahi mineral nani i hoʻohana pinepine ʻia i nā mea nani a me nā mea hoʻonaninani. ʻO ka maʻamau he ʻōmaʻomaʻo ʻōmaʻomaʻo, akā hiki ke loaʻa i nā aka melemele, keʻokeʻo, a me ka hina. ʻO kona hiʻohiʻona maʻalahi ka mea i koho nui ʻia no ka poʻe ʻohi a me ka poʻe hoihoi nā hōʻailona mineral.

I ka hopena, ʻo ka prehnite he mineral hoihoi a waiwai nui i hāʻawi ʻia i ka poʻe kālaihonua a me ka poʻe hoihoi i ka mōʻaukala a me ka honua. Inā he kanaka kālaihonua ʻoe, manaʻolana mākou ua hāʻawi kēia alakaʻi iā ʻoe i kahi ʻike maikaʻi aʻe i ke koʻikoʻi o ka prehnite a pehea e hoʻohana ai i kāu hana.

Ua kapa ʻia lākou ma muli o ko lākou ʻano nahesa, i hana ʻia ma muli o ke alo o ka hao a me ka magnesium. He mea koʻikoʻi nā minela Serpentine ʻaʻole wale no ko lākou mau ʻano kino kūikawā, akā no kā lākou hoʻohana like ʻole i nā ʻano ʻoihana.

ʻO kekahi o nā hiʻohiʻona kaulana loa o nā minela serpentine ko lākou ʻōmaʻomaʻo ʻōmaʻomaʻo, ʻo ia ke kumu o ka hao. Hiki ke keʻokeʻo, melemele, or ʻeleʻele i ke kala. He palupalu maʻamau nā minerala Serpentine a loaʻa kahi ʻano momona a kopa paha. Loaʻa iā lākou kahi ʻano fibrous a columnar ʻokoʻa.

Ma ke ʻano o ka hoʻohana ʻana, loaʻa i nā minela serpentine ka nui o nā noi. Hoʻohana mau ʻia lākou ma ke ʻano he pōhaku hoʻonaninani, a hoʻomaʻamaʻa pinepine ʻia e hoʻonui i ko lākou nani maoli. Hoʻohana pū ʻia nā minelala Serpentine i ka hana ʻana i ka asbestos, kahi mea wela a paʻa i hoʻohana ʻia i ka ʻoihana kūkulu hale no nā makahiki. Eia naʻe, ua kaohi nui ʻia ka hoʻohana ʻana i ka asbestos i nā makahiki i hala iho nei ma muli o kona mau pōʻino olakino.

ʻO kekahi hoʻohana koʻikoʻi o nā mineral serpentine i ka hana ʻana i ka metala magnesium. ʻO ka Magnesium kahi mea koʻikoʻi i hoʻohana ʻia i ka hana ʻana i nā huahana like ʻole, me nā alloys, explosives, a me nā lāʻau lapaʻau. ʻO nā minela Serpentine kahi kumu nui o ka magnesium, no ka mea, aia nā kiʻekiʻe kiʻekiʻe o ka mea.

ka aʻo ʻO nā minela serpentine pili loa i ke kaʻina o ka metamorphism, ʻo ia ka hoʻololi ʻana o nā pōhaku ma o ka wela a me ke kaomi. Hoʻokumu ʻia nā mineral Serpentine i nā pōhaku ultramafic, ʻo ia nā pōhaku i waiwai i ka magnesium a me ka hao. Ke hoʻokau ʻia kēia mau pōhaku i nā wela kiʻekiʻe a me nā koʻikoʻi, hiki ke hoʻololi ʻia nā mineral i loko o lākou i mau mineral serpentine.

I ka hōʻuluʻulu ʻana, ʻo nā mineral serpentine he pūʻulu o nā mineral i ʻike ʻia e ko lākou kala ʻōmaʻomaʻo, ʻano palupalu, a me ke ʻano fibrous a columnar paha. Loaʻa iā lākou nā ʻano hoʻohana, e like me ka pōhaku hoʻonaninani, kahi kumu o ka magnesium, a me kahi ʻāpana o ka asbestos.

He pōhaku makamae ʻo Chrome diopside i ʻike ʻia no kona waihoʻoluʻu ʻōmaʻomaʻo a me nā hiʻohiʻona geologic kūikawā. Loaʻa kēia pōhaku makamae ma nā wahi like ʻole a puni ka honua, me Siberia, Kanada, a me Pakistan. Ma kēia moʻomanaʻo moʻomanaʻo, e nānā pono mākou i ka geology o chrome diopside a e ʻimi i kekahi o kāna mau hiʻohiʻona hoihoi.

ʻO kekahi o nā mea hoihoi loa e pili ana i ka chrome diopside ʻo ia ka mea i hoʻokumu ʻia ma ke kaʻina o ka metamorphism. ʻO ia ke ʻano o ka hana ʻana i ka wā e hoʻololi ai ke kaomi kiʻekiʻe a me nā kūlana wela i ka hoʻololi ʻana i ka hui mineral o nā pōhaku. Hiki ke hana maoli kēia kaʻina hana, e like me ke ʻano o ke kūkulu ʻana i ke kuahiwi or ka aʻo o na pohaku metamorphic. Hiki ke hoʻoulu ʻia me ka artificial, e like me ke ʻano o kekahi mau hana ʻoihana.

ʻO ka Chrome diopside kekahi ʻano o ka calcium magnesium silicate, ʻo ia hoʻi, ua haku ʻia me nā minerala calcium, magnesium, a me silicate. Loaʻa pinepine ia i loko o nā pōhaku i loaʻa ka silica kiʻekiʻe, e like me ke kinikini a i ʻole gneiss. Ma waho aʻe o kona kala ʻōmaʻomaʻo kūʻokoʻa, ʻike ʻia ka chrome diopside no kona paʻakikī a paʻa. Loaʻa iā ia ka paʻakikī Mohs o 5.5 a 6, kahi mea paʻakikī a paʻakikī hoʻi i ka lole a me ka waimaka.

ʻO kekahi o nā waihona kaulana loa o ka chrome diopside aia ma nā mauna Ural o Siberia. Ua ʻike mua ʻia kēia waihona i ka hopena o 1800s a ua ʻeli ʻia no ka pōhaku makamae mai ia manawa. Ma waho aʻe o Siberia, hiki ke ʻike ʻia ka chrome diopside ma Kanada, ʻoi loa ma ka ʻāina Thunder Bay o Ontario. Maʻaneʻi, loaʻa ka pōhaku makamae i ka mea i kapaʻiaʻo "diopside pipes,"ʻo ia nā paipu pele kahiko i hanaʻia he mau miliona makahiki i hala.

ʻO kekahi hiʻohiʻona hoihoi o ka geology o chrome diopside kona hui pū ʻana me nā minela ʻē aʻe. I kekahi mau hihia, hiki ke loaʻa me nā pōhaku makamae ʻē aʻe e like me ke daimana, emerald, a me ka ruby. Hiki ke loaʻa iā ia ma nā ʻano pōhaku like me nā minerala ʻē aʻe, e like me pyroxene, amphibole, a me olivine.

I ka hopena, ʻo ka chrome diopside he pōhaku makamae i ʻike ʻia no kāna mau hiʻohiʻona kūlohelohe. Hoʻokumu ʻia ia ma o ke kaʻina hana o ka metamorphism a loaʻa i kekahi mau wahi like ʻole a puni ka honua, me Siberia, Kanada, a me Pakistan. ʻO kona waihoʻoluʻu ʻōmaʻomaʻo ʻokoʻa, paʻakikī, a me ka lōʻihi e lilo ia i koho kaulana no nā mea nani a me nā mea hoʻonaninani ʻē aʻe. Inā makemake ʻoe e aʻo hou aʻe e pili ana i ke kālaihonua o chrome diopside a i ʻole nā ​​pōhaku makamae ʻē aʻe, nui nā kumuwaiwai e kōkua iā ʻoe e ʻimi i kēia kumuhana hoihoi.

ʻO Pyrite, ka mea i kapa ʻia ʻo ke gula naʻaupō, he mineral sulfide maʻamau i loaʻa i nā ʻano hoʻonohonoho honua. Loaʻa iā ia kahi kala keleawe-melemele ʻokoʻa a me ka ʻulaʻula metala, i alakaʻi ai i kona inoa kapakapa. ʻOiai ua like paha ia me ke gula i ka maka i hoʻomaʻamaʻa ʻole ʻia, ʻokoʻa maoli ka pyrite ma ke ʻano o kona ʻano kino a me ke kino.

ʻO ka Pyrite he ʻano aniani cubic, me kēlā me kēia mole i haku ʻia me ka hao a me nā ʻātoma sulfur i hoʻonohonoho ʻia ma kahi ʻano kikoʻī. Loaʻa ia ma ke ʻano o nā kristal liʻiliʻi i hana maikaʻi ʻia, ʻoiai hiki ke hana ʻia ma ke ʻano he nui, granular aggregates.

Loaʻa ka Pyrite i loko o nā kaiapuni honua like ʻole, e like me nā pōhaku sedimentary, nā pōhaku metamorphic, a me nā waihona hydrothermal. Hoʻohui pinepine ʻia me nā minerale ʻē aʻe e like me quartz, calcite, a me ka galena.

ʻO kekahi o nā hiʻohiʻona ʻokoʻa o ka pyrite ʻo kona paʻakikī. Ma ka pālākiō Mohs, i hoʻohana ʻia e ana i ka paʻakikī o nā minerala, hāʻule ka pyrite i kahi 6.5, ʻoi aku ka palupalu ma mua o ka quartz akā ʻoi aku ka paʻakikī ma mua o ka talc. He mea maʻalahi kēia e ʻohi me ka pahi or mea ʻoi ʻē aʻe, akā paʻakikī ke ʻoki ʻia a pulverize.

Ma ka ʻāina, hiki ke loaʻa ka pyrite ma ka honua holoʻokoʻa, ʻoiai ʻoi aku ka maʻamau i kekahi mau wahi. Loaʻa pinepine ia ma nā waihona nui ma nā wahi e like me ʻAmelika Hema, Sepania, a me Kina. I ka ʻAmelika Hui Pū ʻIa, loaʻa maʻamau ia ma nā mauna ʻo Appalachian a ma nā mokuʻāina komohana, ʻo ia hoʻi ma Nevada a Hawaii.

ʻO kekahi o ka hoʻohana nui ʻana o ka pyrite he ʻano hao. He mea nui ka hao i ka hana ʻana i ke kila, a he kumu nui ka pyrite o kēia metala. Ma waho aʻe o kona hoʻohana ʻana i ka ʻoihana kila, hoʻohana pū ʻia ka pyrite ma ke ʻano he kumu sulfur a ma ke ʻano he catalyst i ka ʻoihana kemika.

ʻO Pyrite kekahi mea pāʻani nui i ka aʻo ʻO ka waiʻawaʻawa mine drainage, ʻo ia ka mea e hopohopo nui ai i ke kaiapuni ma nā wahi he nui o ka honua. Ke ʻike ʻia ka pyrite i ka ea a me ka wai, hana ia e hana i ka sulfuric acid, hiki ke hoʻokuʻu i nā metala kaumaha a me nā mea make ʻē aʻe mai ka pōhaku a me ka lepo a puni. Hiki i kēia ke hoʻohaumia i nā lako wai a hoʻopilikia nui i ke kaiapuni.

ʻOiai ka hopena maikaʻi ʻole o ke kaiapuni, noho mau ʻo pyrite i mineral koʻikoʻi i ka geology a me nā ʻoihana mining. ʻO kāna mau waiwai kūʻokoʻa a me ka laha ʻana e lilo ia i kumu waiwai nui e hoʻomau ʻia e hoʻohana ʻia no nā makahiki he nui e hiki mai ana.

ʻO ka maka tiger ʻulaʻula he mineral maikaʻi loa i mahalo ʻia no kāna mau kala a me nā ʻano like ʻole. Hoʻohana pinepine ʻia i nā mea nani a me nā mea hoʻonaninani ʻē aʻe ma muli o kona nani maoli a me ka lōʻihi. Akā, he aha ka mea e pili ana i ka maka tigre ʻulaʻula i mea kūikawā?

He ʻano like ʻole ka maka tigre ʻulaʻula quartz, he mineral maʻamau i loaʻa i nā ʻano pōhaku he nui. Hana ʻia ia i loko o nā pōhaku metamorphic, ʻo ia nā pōhaku i hoʻololi ʻia e ka wela a me ke kaomi. Ke hoʻokau ʻia ka quartz i kēia mau kūlana, hiki iā ia ke lawe i nā waiwai a me nā kala hou, e hopena i nā minerale e like me ka maka tiger ʻulaʻula.

Loaʻa ka maka tiger ʻulaʻula i kona waihoʻoluʻu ʻokoʻa mai ka iron oxide, aia i loko o ka mineral ma nā mea liʻiliʻi. Ke ʻike ʻia ka hao ʻokesaʻe i ka mālamalama, e hoʻihoʻi mai ia i nā lōʻihi nalu ʻulaʻula, e hāʻawi ana i ka maka tigra ʻulaʻula i kona ʻano ʻulaʻula. Hiki ke waihoʻoluʻu ke kala o ka maka tiger ʻulaʻula mai ka ʻulaʻula ʻulaʻula a i ka ʻulaʻula hohonu, ma muli o ka nui o ka hao oxide i loaʻa.

Ma waho aʻe o kona kala, ʻike ʻia ka maka tiger ʻulaʻula no kāna kamaʻilio ʻana, or ka hiki ke hoʻomālamalama i ka mālamalama i loko o kahi ʻāpana haiki. Hāʻawi kēia i ka mineral i ka hopena "maka cat", ʻo ia ke kumu i kapa pinepine ʻia ai he maka tiger. ʻO ka chatoyancy o ka maka tiger ʻulaʻula ma muli o ka hoʻonohonoho ʻana o nā fibers i loko o ka mineral, e hōʻike ana i ka mālamalama i kekahi ʻano.

ʻO ka maka tiger ʻulaʻula he nui nā hoʻohana pono i hoʻohui ʻia i kāna waiwai hoʻonaninani. He mineral paʻakikī ia, e kūpono ai no ka hoʻohana ʻana i nā mea nani a me nā mea ʻē aʻe i hiki ke hoʻopaʻa ʻia. Manaʻo ʻia ka maka tiger ʻulaʻula he mau mea ho'ōla a hoʻohana pinepine ʻia i ka lāʻau kuʻuna a me nā hana ʻuhane.

I ka hopena, ʻo ka maka tiger ʻulaʻula he mineral hoihoi i mahalo ʻia no kona kala kūʻokoʻa a me kona ʻano. Kona aʻo i loko o nā pōhaku metamorphic a me ka loaʻa ʻana o ka iron oxide i kona ʻano ʻulaʻula a me ka chatoyancy. ʻO ʻoe he mea hoihoi i ka geology a mahalo wale paha i ka nani o nā minerala, ʻo ka maka tiger ʻulaʻula he mineral hoʻohiwahiwa a maʻalahi i kūpono ke ʻimi.
