He mau minera kekona?

ʻO ka mineral he mea hoʻohui kūlohelohe maoli, maʻamau o ka crystalline form a hana ʻole ʻia e nā kaʻina ola. Loaʻa iā ia kahi hoʻohui kemikal kikoʻī, akā hiki i ka pōhaku ke hōʻuluʻulu o nā minelala ʻokoʻa. ʻO ka ʻepekema he mineralogy.

ʻO ka hapa nui o nā pōhaku makamae he minerals

Loaʻa iā lākou nā ʻano ʻokoʻa kino. Depsnds kā lākou wehewehe ʻana i kā lākou hanana kemika a me kā lākou haku ʻana. ʻO nā hiʻohiʻona ʻokoʻa e pili ana i ke ʻano aniani a me ka maʻamau, a me ka paʻakikī, alohilohi, diaphaneity, kala, kahakaha, paʻa, paʻa, haʻi, hoʻokaʻawale, umekaumaha, magnetism, ʻono a ʻaʻala paha. radioactivity, a me ka hopena i ka waikawa.

Hōʻike o ka mineral: Quartz, diamona, corrundum, beryl,…

kemikala gemstones

He mea nui e hoʻokaʻawale i waena o nā pōhaku synthetic, a me nā mea hoʻohālikelike a i ʻole nā ​​mea i hoʻohālikelike ʻia.

Kū like ke kino, nā optically a me nā kemika i nā pōhaku kūlohelohe, akā i hana ʻia i kahi hale hana. I ka maket kalepa, hoʻohana pinepine nā mea kūʻai pōhaku i ka inoa "lab hana". Hana ia i ka pōhaku synthetic ʻoi aku ke kūʻai aku ma mua o ka "hale hana hana".

Exemple of Synthetic pōhaku: Synthetic corrundum, synthetic diamond, synthetic quartz,…

Nā pōhaku i haku ʻia

ʻO nā laʻana o nā pōhaku ʻĀpala e komo pū me ka cubic zirconia, i haku ʻia o zirconium oxide a me moissanite simulate, ʻo nā pōhaku ʻelua ia. ʻO nā kope hoʻohālike kope i ka nānā a me ke kala o ka pōhaku maoli akā ʻaʻole i loaʻa i ko lākou kemika a me ko lākou ʻano kino.

Loaʻa ʻo Moissanite i kahi papa kuhikuhi kiʻekiʻe ʻoi aku ka kiʻekiʻe ma mua o ke daimana a ke hōʻike ʻia ma ka ʻaoʻao o kahi kaulike a ʻokiʻoki ʻia ka diamona e ʻoi aku ka "ahi" ma mua o ka diamona.

pohaku

He mea kūlohelohe ka pōhaku, kahi hōʻuluʻulu paʻa o hoʻokahi a ʻoi aku nā minela a mineraloids paha. ʻO kahi laʻana, ʻo Lapis lazuli kahi pōhaku metamorphic polū hohonu. ʻO kona hoʻonohonoho ʻana he pōhaku semi-waiwai nui. ʻO ka mea nui o ka lapis lazuli ka lazurite (25% a 40%), kahi silicate feldspathoid.

Nā pōhaku pōhaku

He nui nāʻano mea kanu i hoʻohanaʻia me nā pōhaku, e like me:
Amber, 'Ammolite, Iwi, Copal, ke'ākoʻakoʻa, Ivory, Jet, Nacre, Operculum, Momi, Pōhaku Petoskey

ʻO ka mineraloids

ʻO ka mineraloid kahi mea like me ka mineral e hōʻike ʻole i ka crystallinity. Loaʻa i nā Mineraloids nā mele kemika i ʻokoʻa ma waho o nā pae i ʻae ʻia no nā minela kikoʻī. ʻO kahi laʻana, ʻo ka obsidian he aniani aniani ʻaʻole ia he aniani.

Ua loaʻa mai ka mokulele mai ka wahie popopo ma lalo o ke kaomi nui loa. ʻO Opal kekahi mea hou aʻe no kona ʻano non-crystalline.

Hanaʻia nā mineraloids

Ke kīʻaha i hanaʻia e ke kanaka, he paʻi, ...

Kūʻai aku nā pōhaku kūlohelohe i ko mākou hale kūʻai gem
