pōʻai hoʻololi kala

Hoʻololi ʻo Sphene a i ʻole Titanite i ka waihoʻoluʻu mai ka ʻōmaʻomaʻo a i ka ʻulaʻula.

ʻO ka pōpō hoʻololi kala, a i ʻole titanite, he mineral calcium non-silicate i kapa ʻia ʻo CaTiSiO5. Loaʻa pinepine ʻia ka nui o ka hao a me ka aluminika. He mea maʻamau nā metala honua, me ka cerium a me ka yttrium. Hoʻololi hapa ʻo Thorium i ka calcium me ka thorium.

Titanite

Hiki ke Sphene ma ke ʻano he translucent i ka ʻulaʻula ʻulaʻula ʻulaʻula, a me nā kristal monoclinic hina, melemele, ʻōmaʻomaʻo a ʻulaʻula paha. ʻO kēia mau kristal e pili pinepine a pālua pinepine. Loaʻa i ka subadamantine, me ka liʻiliʻi resinous luster, titanite he paʻakikī o 5.5 a me kahi ʻoki nāwaliwali. ʻO kona mānoanoa ma muli o 3.52 a me 3.54.

ʻO ka index refractive o titanite mai 1.885-1.990 a 1.915-2.050 me ka birefringence ikaika mai 0.105 a 0.135, biaxially maikaʻi, ma lalo o ka microscope e alakaʻi i kahi hōʻoluʻolu nui, i hui pū ʻia me ke kala melemele-ʻeleʻele maʻamau. ma ke ʻano he ʻāpana keʻa daimana, hoʻomaʻamaʻa i ka ʻike ʻana o ka mineral.

Hoʻokaʻawale ʻia nā hiʻohiʻona māmā e ka trichroism ikaika, a ʻo nā kala ʻekolu i hōʻike ʻia ma muli o ke kala o ke kino. Ma muli o ka hopena kinai ʻana o ka hao, ʻaʻole e lele ka pōhaku i ke kukui ultraviolet.

Ua ʻike ʻia kekahi o ka titanite he metamictite ma muli o ka pōʻino o ke kūkulu ʻana ma muli o ka palaho radioactive o ka maʻiʻo thorium nui. Ke nānā ʻia ma ka ʻāpana lahilahi me kahi microscope petrographic, hiki iā mākou ke nānā i ka pleochorism i loko o nā minela e hoʻopuni ana i ka aniani titanite.

ʻO Spen kahi kumu o ka titanium dioxide TiO2 i hoʻohana ʻia i nā puaʻa.

Ma ke ʻano he pōhaku makamae, ʻo ka titanite ka mea maʻamau i ke aka hina, akā hiki ke ʻeleʻele a ʻeleʻele paha. ʻO ka hue e pili ana i ka Fe maʻiʻo: ʻo ka haʻahaʻa Fe maʻiʻo e hua mai i nā ʻōmaʻomaʻo a me ka melemele, ʻoiai ʻo ka maʻiʻo Fe kiʻekiʻe e hana i nā ʻeleʻele a ʻeleʻele paha.

He mea maʻamau ka zoning no nā titanites. Manaʻo ʻia no kona mana hoʻopuehu kūʻokoʻa o 0.051 i ka pae B a G, ʻoi aku ka daimana. He kakaikahi ka mea nani o Spen, he kakaikahi ka pohaku makamae a palupalu.

Hoʻololi kala

ʻO kahi laʻana maikaʻi o ka hoʻololi kala ʻo sphene. ʻOkoʻa loa kēia mau pōhaku a me nā pōhaku ma lalo o ke kukui uila ma mua o ka lā maoli. ʻO ka hapa nui kēia ma muli o ke ʻano kemika o nā pōhaku a me ka hoʻopili koho ikaika.

ʻIke ʻia ʻo Sphene i ka ʻōmaʻomaʻo i ka lā a me ka ʻulaʻula i ke kukui kukui. ʻO Sapphire, a me tourmaline, alexandrite a me nā pōhaku ʻē aʻe, hiki ke hoʻololi i ke kala.

Kūʻai ʻia ka sphene kūlohelohe ma kā mākou hale kūʻai pōhaku

Hana mākou i nā mea nani me nā kristal i ke ʻano o nā apo mare, nā lei, nā apo pepeiao, nā kūpeʻe lima, nā pendants… E ʻoluʻolu e kelepona mai iā mākou no kahi ʻōlelo.
