No ke aha i ikaika a paʻa ka pōhaku granite?
Graniteʻo ia kekahi o nā pōhaku ikaika loa o ka pōhaku. ʻAʻole paʻakikī wale nō, akā ʻaʻole hiki ke hoʻoheheʻe ʻia e ka wai. ʻAʻole hiki ke hoʻopau ʻia e ka waikawa a me ka alkali. Hiki iā ia ke pale aku ma mua o 2000 kg o ke kaomi no ke kenimika square. ʻAʻole ʻike ʻia ka hopena o ke anuanu no nā makahiki.

He nani mau ke ʻano o ka granite, ʻike pinepine ʻiaʻeleʻele, keʻokeʻo, hinahina, melemele, waihoʻoluʻu pua, rose a me nā kala pāpaʻu, intersperse i ka ʻeleʻele wahi, nani a lokomaikaʻi. ʻO nā pōmaikaʻi ma luna, lilo ia i mea koho kiʻekiʻe ma ka pōhaku kūkulu. ʻO ka pōhaku puʻuwai o ke kia hoʻomanaʻo i nā poʻe koa o ka poʻe ma ka pā tiananmen o Beijing i hana ʻia mai kahi ʻāpana pōhaku i hoʻouna ʻia mai laoshan, ka ʻāina ʻo Shandong.

No ke aha i loaʻa ai kēia mau ʻano o ka granite?
E nānā mua kākou i kāna mau mea. ʻO nā ʻāpana mineral e hana i ka granite, ʻoi aku ma mua o 90% nā minerala ʻelua, feldspar a me quartz, ʻo ia hoʻi ka feldspar loa. He keʻokeʻo keʻokeʻo ʻo Feldspar, hina, ʻulaʻula, a me ka quartz ʻaʻohe kala a hina paha, ʻo ia ka mea i hoʻokumu i nā hue kumu o ka granite. ʻO Feldspar a me ka quartz nā mineral paʻakikī a paʻakikī ke neʻe me nā pahi kila. No nā wahi ʻeleʻele i loko o ka granite, ʻo ka mika ʻeleʻele a me nā minerale ʻē aʻe. ʻOiai he palupalu ka mica ʻeleʻele, ʻaʻole nāwaliwali i ka pale ʻana i ke kaomi, a ʻo kona mau mea i loko o ka granite he liʻiliʻi loa, ʻoi aku ka liʻiliʻi ma mua o 10%. ʻO kēia ke kūlana waiwai paʻa loa o ka granite.
ʻO kekahi kumu ʻē aʻe i ikaika ai ka granite, ʻo ia ka paʻa ʻana o kāna mau ʻano minerala i kekahi i kekahi, a ʻo ka helu pinepine ʻana o nā pores ma lalo o 1% o ka nui o ka nui o ka pōhaku. Hāʻawi kēia i ka granite i ka hiki ke pale i ke kaomi ikaika a ʻaʻole hiki ke komo maʻalahi i ka wai.

ʻOiai he ikaika loa ka Granite, akā i ka wā lōʻihi o ka lā, ka ea, ka wai a me ka biology, e hiki mai ana ka lā "popopo", hiki iā ʻoe ke manaʻoʻiʻo? ʻO ka nui o ke one i loko o ka muliwai, ʻo ia nā ʻāpana quartz i waiho ʻia ma hope o ka luku ʻia ʻana, a ʻo ka pālolo i hoʻolaha nui ʻia he huahana nō hoʻi ia o ka ʻino o ka granite. Akā, e lōʻihi ana ka manawa, no laila ma ke ʻano o ka manawa kanaka, paʻa loa ka granite.
