He aha nā pōhaku maʻemaʻe a ma hea e hiki ai ke hoʻohana ʻia? pōhaku ʻāina

No ke aha kekahi pōhaku maoli i manaʻo ʻia he palupalu ke ʻike ʻia he paʻakikī? Aia ka pane i loko o ka 'pilikia' paakiki. Ua haku ʻia ka pālākiō Mohs i ka makahiki 1812 a ua hoʻohālikelike ʻia ka paʻakikī pili o nā minela he ʻumi. ʻO ka daimana ka paʻakikī loa a he 10, ʻoiai ʻo ka granite ka pōhaku maoli ʻoi aku ka paʻakikī ma 6. Hele mai ka Limestone ma 3 e like me kāna mea metamorphic, marble. ʻOi aku ka maʻalahi o ka pōhaku palupalu i ka lole a i ʻole ke kalai ʻana akā ʻaʻole ʻaʻahu a ʻaʻahu ʻole e like me ka pōhaku ʻoi aku ka paʻakikī. Maanei mākou e kūkākūkā ai i kekahi o nā pōhaku palupalu kaulana loa me nā noi kūpono.

ʻO nā pōhaku kūponoʻole

pōhaku sedimentary

ʻO ka limestone, ke one a me ka shale ka mea maʻamau o ka pōhaku sedimentary. Ua hoʻokumu ʻia kēia mau mea ma muli o ke kaomi nui ʻana, i loko o nā miliona mau makahiki, e kau ana i ka sediment i hāʻule i ka papahele o ka moana.

Slate

Hōʻike ʻia nā papa o ka slate he "foliated" a ua maʻalahi lākou e hoʻokaʻawale ʻia e hana i kēlā me kēia mānoanoa e pono ai. Ua manaʻo ʻia ka pāpaʻi UK he paʻakikī a ua hoʻohana maʻamau ʻia ma ke ʻano he kaupaku, ʻoiai ʻike ʻia ka papa ma Kina, Sepania, Italia a me USA. Me ka laulā o nā waihoʻoluʻu maoli, hiki ke hoʻokō ʻia nā ʻano hoʻolālā he nui, mai ka wā kahiko a i ka maʻamau, rustic a i hoʻomaʻemaʻe ʻia. Manaʻo pinepine ʻia ʻo Slate no nā wahi kaʻa kiʻekiʻe, mahalo i kāna haku mele ʻana. ʻAʻole ia he porous a ʻaʻole maʻalahi ke hana me ka wai ʻakika. He pale ahi ia, pale i ka wā a loaʻa i ka pale paheʻe maikaʻi ma muli o kona pau ʻana.

Limestone

He mea hale maʻamau ka Limestone a ua hana nui ʻia mai ka mineral calcite, i loaʻa mai ka calcium i loko o nā iwi a me nā ʻili kai i waiho ʻia ma luna o nā millennia a hoʻoikaika pū ʻia me ke kaomi. ʻOiai he magnesium kekahi, ʻoi aku ka paʻakikī a ʻoi aku ka pale ʻana i ka wā, a hiki ke hoʻomaʻamaʻa ʻia. ʻO ka pōhaku ʻo Portland mai ka mokupuni eponymous ma Dorset ʻo ia paha ke ʻano pōhaku kaulana loa a ua hoʻohana ʻia e kūkulu i nā hale nui o Lākana. Hoʻohana ʻia ia no ka pale ʻana i waho a me ka paving, nā kapuahi a me nā hiʻohiʻona hoʻonaninani kūloko a me waho. ʻO kona mau kala palupalu kona mau hiʻohiʻona ʻike maka.

Pōhaku one

ʻO Sandstone paha ka pōhaku kūkulu maʻamau ma mua o ka makahiki 1800, no nā mea a pau mai nā alahaka a i nā hale hanohano. E like me ka mea i ʻike ʻia mai kona inoa, ua hana ʻia ia i ka wā i hui pū ʻia ai ke one, nā mea organik, calcite a me nā ʻano mineral ʻē aʻe ma lalo o ke kaomi nui ʻana i nā millennia. Loaʻa ʻia me ka ʻano ʻano ʻano ʻano ʻano a i ʻole ke ʻano maikaʻi a hāʻawi ʻia ma ke ʻano matt. ʻO ka cream, ʻulaʻula a hina paha ma UK, ʻo kona kala e pili ana i nā minerala hou i loko. Hāʻawi ka Silica i ka keʻokeʻo, ʻoiai e hāʻawi ka hao i kahi ʻulaʻula-ʻulaʻula. ʻO kāna mau wahi nui o ka noi ʻana he mau paia a me ka papahele, a i ʻole ka paving waho.

kinikini

ʻO ka marble kahi mea i loaʻa i ka limestone, i hana ʻia ma o ka metamorphosis o ka wela nui a me ke kaomi ma luna o nā miliona mau makahiki. ʻOiai maʻalahi ke hoʻohālikelike ʻia me nā pōhaku ʻē aʻe, ʻoi aku ka maikaʻi o ka poli ʻana i ka marble. Hoʻohana ʻia ke kinikini maʻamau i nā puka a kōkua i ka hana ʻana i kahi hopena kiʻekiʻe.
