Lawe iā ʻoe ma waena o nā pōhaku - granite

ʻO Granite ka ʻano pōhaku ākea loa ma ka ʻili.Hoʻokumu ia i ka nui o ka ʻōpala ʻāina i ulu nui ʻia ma ke ʻano o kona haku mele ʻana a he hōʻailona koʻikoʻi ia e hoʻokaʻawale ai ka Honua mai nā hōkū ʻē aʻe.Paʻa ia i nā mea huna o ka ulu ʻana o ka ʻāina ʻāina, ka ulu ʻana o ka ʻahu a me ka ʻōpala, a me nā kumuwaiwai mineral.

Ma ke ʻano o ka genesis, ʻo ka granite kahi pōhaku magmatic acidic intrusive hohonu, kahi i hana ʻia ma ke ʻano he kumu pōhaku a i ʻole kānana.ʻAʻole paʻakikī ke hoʻokaʻawale i ka granite ma kona ʻano;ʻO kona hiʻohiʻona ʻokoʻa kona ʻano haʻalulu, ʻulaʻula ka nui o ka ʻiʻo.ʻO nā minelala nui i hana i ka granite he quartz, feldspar a me ka mica, no laila e ʻokoʻa ke kala a me ka luster o ka granite ma muli o ka feldspar, mica a me nā mineral ʻeleʻele.I loko o ka granite, he 25-30% ka nui o ka quartz, he ʻano aniani kona ʻano me kahi aniani momona;ʻO ka potassium feldspar ka helu no 40-45% o ka feldspar a me ka plagioclase 20%.ʻO kekahi o nā waiwai o ka mica ʻo ia ka hiki ke hoʻokaʻawale ʻia i nā flakes lahilahi me kahi nila ma ka deconstruction.I kekahi manawa hele pū ʻia ka granite me nā mineral paramorphic e like me amphibole, pyroxene, tourmaline a me garnet, akā he mea maʻamau a ʻike ʻole ʻia kēia.

ʻO nā mea maikaʻi o ka granite he mea koʻikoʻi, he homogeneous, paʻakikī, emiʻole ka wai, hiki i ka ikaika compressive o ka pōhaku pōhaku ke hiki i ka 117.7 a hiki i ka 196.1MPa, no laila, ua manaʻo pinepineʻia he kumu maikaʻi no nā hale, e like me Three Gorges, Xinfengjiang, Ua kūkulu ʻia ʻo Longyangxia, Tenseitan a me nā wai wai ʻē aʻe ma luna o ka granite.ʻO Granite kekahi pōhaku hale maikaʻi loa, he paʻakikī maikaʻi, a he ikaika compressive kiʻekiʻe, porosity liʻiliʻi, haʻahaʻa wai absorption, wikiwiki thermal conductivity, maikaʻi ʻaʻahu kūpaʻa, kūpaʻa kiʻekiʻe, kūpaʻa hau, kūpaʻa ʻakika, kūpaʻa corrosion, ʻaʻole maʻalahi i ka wā. , no laila hoʻohana pinepine ʻia e kūkulu i nā alahaka, nā ʻanuʻu, nā alanui, akā no nā hale pōhaku, nā pā a pēlā aku.ʻAʻole ikaika a kūpono ka Granite, akā he ʻano maʻalahi hoʻi me nā kihi maʻemaʻe, no laila ua hoʻohana pinepine ʻia i loko o ka hoʻonaninani kūloko a manaʻo ʻia he pōhaku hoʻonaninani kiʻekiʻe.

ʻAʻole ʻo Granite he ʻano pōhaku hoʻokahi, akā he nui nā ʻano like ʻole, e hōʻike ana kēlā me kēia mea i nā waiwai like ʻole e pili ana i nā mea i hui ʻia.Ke hui pū ʻia ka granite me ka orthoclase, ʻike pinepine ʻia ka ʻulaʻula.ʻO nā granite ʻē aʻe he hina a i ʻole, ke hoʻololi ʻia, he ʻōmaʻomaʻo ʻeleʻele.
