ʻO Kina pōhaku maoli nui ʻeleʻele ʻeleʻele ʻeleʻele patio paving slabs

Hoʻokumu ʻia nā hui i loko o ka pāpaʻi ma muli o ka hoʻomohala ʻana o nā microscopic mica flakes, ʻaʻole ma ka māhele ʻana ma ka ʻāpana sedimentary mua.

Hoʻokumu ʻia ka Slate i ka wā i kanu ʻia ai ka pōhaku lepo, shale, a i ʻole felsic igneous pōhaku a hoʻokau ʻia i nā mahana haʻahaʻa a me ke kaomi.

ʻO ka Slate he ʻeleʻele maikaʻi loa a ʻike ʻole ʻia e ka maka kanaka. He matte ka ʻili o ka papa poli i hoʻopaʻa ʻia akā ua maʻalahi i ka hoʻopā ʻana a ua hoʻohana mua ʻia e hana i nā papa ʻeleʻele. ʻO nā mea liʻiliʻi o ka mika silika e hāʻawi i ka papa i ke aniani silika silika.

Hōʻike ʻia ka Slate ma nā ʻano kala like ʻole ma muli o nā ʻokoʻa o nā ʻano minerala a me nā kūlana oxidation i loko o ke kaiapuni sedimentary kumu. No ka laʻana, ua hoʻomohala ʻia ka pāpaʻi ʻeleʻele ma kahi ʻano oxygen-deficient, akā ua hana ʻia ka ʻulaʻula i loko o kahi mea momona oxygen.

Loaʻa ka Slate ma lalo o nā haʻahaʻa haʻahaʻa a me nā pilikia, no laila e mālama ʻia nā mōʻalihaku mea kanu a me kekahi mau hiʻohiʻona noʻonoʻo maoli.

Hoʻohana ʻia ʻo Slate ma nā poloka nui a hoʻohana ʻia no nā panela hoʻokele uila, nā papa hana, nā papa ʻeleʻele, a me nā papahele ma muli o kona ʻano like me ka pāpaʻi, kūpaʻa, a me ka hoʻopau ʻana. Hoʻohana ʻia nā papa liʻiliʻi e kūkulu i nā hale.

Inā he mauna kiʻekiʻe a he awāwa hohonu paha, he kūlanakauhale nui a he ʻāina maluhia paha, ʻo ke kūlana kupaianaha a me ka maikaʻi paʻa o ka slate e kākoʻo mau i ke ola a me ka hana o nā kānaka. ʻO kēia ka slate, kahi ola maʻamau akā kūpaʻa, he pōhaku e mālama ai i nā piliona makahiki o nā moʻolelo a me nā hoʻomanaʻo.
