Hiki ke hoʻohana ʻia ka Slate i nā hale, nā papahele, nā kīhāpai a me nā wahi ʻē aʻe, akā he pōhaku hoʻonani maikaʻi hoʻi, he ʻano ʻano pōhaku maoli, he aha ka slate?ʻAʻole ʻike nui ka poʻe i kēia ʻano pōhaku.Pehea i hoʻokumu ʻia ai ka slate?Mao hopohopo.E kamaʻilio kākou no ia mea.E nānā kāua.

He aha ka papa?

ʻO ka Slate kahi ʻano pōhaku metamorphic me ke ʻano o ka papaha a ʻaʻohe hoʻohou hou.ʻO ka pōhaku kumu he argillaceous, silty a neutral tuff, hiki ke wehe ʻia i loko o nā ʻāpana lahilahi ma ke ala o ka slate.Hoʻokumu ʻia ia e ka metamorphism liʻiliʻi o ka pālolo, nā pōhaku sedimentary silty, nā pōhaku tuffaceous intermediate-acid a me nā pōhaku tuffaceous sedimentary.
Ma muli o ka dehydration, ua hoʻonui ʻia ka paʻakikī o ka pōhaku kumu, akā ʻaʻole e hoʻihoʻi hou ʻia ka haku melemele.Loaʻa iā ia kahi ʻano metamorphic a me ke ʻano metamorphic, a ʻo kona ʻano he ʻeleʻele a hūnā i ka crystallization.He maikaʻi loa nā ʻāpana mineral, he paʻakikī ke ʻike ʻia e nā maka maka.Loaʻa pinepine ka liʻiliʻi o ka sericite a me nā minela ʻē aʻe ma luna o ka ʻili o ka pā, kahi e hoʻoheheʻe iki ai ka ʻili o ka pā.Hiki ke kapa ʻia ka inoa ma ke ʻano kikoʻī e like me nā kala ʻokoʻa like ʻole, e like me ka papa kalapona ʻeleʻele a me ka ʻōmaʻomaʻo calcareous slate hina.I ka haʻahaʻa haʻahaʻa thermal contact metamorphism, hiki ke hoʻokumu ʻia nā pōhaku metamorphic pāpaʻu me nā hale kiko a me nā pā, i kapa ʻia he "pōhaku ʻikea".Hiki ke hoʻohana ʻia ka Slate e like me nā mea kūkulu hale a me nā mea hoʻonaninani.I ka wā kahiko, hoʻohana mau ʻia ʻo ia ma ke ʻano he tile ma nā wahi momona i ka slate.

Pehea i hana ʻia ai ka papa?

ʻO ka pāpaʻi, e like me ke one, he pōhaku sedimentary i hana ʻia e ka neʻe ʻana o ka honua a me ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana o nā ʻano one a me nā sima (mea siliceous, calcium carbonate, pālolo, iron oxide, calcium sulfate, a me nā mea ʻē aʻe) ma lalo o ka nui o ka wā lōʻihi. kaomi.I kēia manawa, ʻo nā kala nui he uliuli māmā, ʻeleʻele, ʻōmaʻomaʻo māmā, ʻulaʻula, ʻeleʻele, hina hina, melemele a pēlā aku.ʻAʻole waiwai wale ʻo Slate i ke ʻano, akā paʻakikī hoʻi, ka waihoʻoluʻu nani, haʻahaʻa wai absorption, ʻaʻohe pollution radiation, me ka matt, anti-skid, acid and alkali resistance, ke ahi a me ke anuanu, ke kū'ē i ka wā, crackability maikaʻi a me nā ʻano ʻē aʻe.

ʻO ka mea hoʻohui mineral ka mea nui o ka mika, a ukali ʻia e ka chlorite, quartz, kahi liʻiliʻi o ka pyrite a me ka calcite.ʻOi aku ka nui o ke one, ka nui o ka calcium a me ka pyrite, a me ka lithology paʻakikī.ʻO nā kino oka he calcareous sericite a me ka silty sericite me ka mānoanoa papa hoʻokahi o 1-5 cm.
Hoʻokumu ʻia nā pōhaku metamorphic pāpaʻu e ka metamorphism liʻiliʻi o ka pālolo, nā pōhaku sedimentary silty, nā pōhaku tuffaceous intermediate-acid a me nā pōhaku sedimentary tuffaceous.ʻeleʻele a hina-ʻeleʻele.Paʻa ka lithology a ua hoʻomohala maikaʻi ʻia ka ʻāpana pā.Loaʻa pinepine ka liʻiliʻi o ka sericite a me nā minela ʻē aʻe ma luna o ka ʻili o ka pā, kahi e hoʻoheheʻe iki ai ka ʻili o ka pā.ʻAʻohe mea i ʻike ʻia ka recrystallization.ʻO ka microscopically, ʻo kekahi mau ʻano minerala, e like me ka quartz, sericite a me ka chlorite, ua māhele like ʻole ʻia, akā ʻo ka hapa nui o ia mau mea he cryptocrystalline clay minerals a me carbonaceous a me nā pauka hao.Loaʻa iā ia ka hoʻolālā redundant a me ke ʻano kikoʻī.
ʻO nā pōhaku mua me ka pāpaʻa ʻo ka nui o nā pōhaku argillaceous, argillaceous siltstone a me waena-acid tuff.He huahana haʻahaʻa haʻahaʻa ʻo Slate o ka metamorphism kūloko, a ʻaʻole kiʻekiʻe kona wela a me ke ʻano like ʻole, kahi i hoʻopilikia nui ʻia e ke kaumaha.ʻO ka lamellar cleavage metamorphic pōhaku me nā ʻāpana argillaceous a me ka silty e like me nā mea nui a me nā ʻāpana argillaceous a me nā ʻāpana e like me nā mea nui e hiki ke hoʻohana ʻia e like me ke kūkulu ʻana i ka pōhaku, ka stele a me ka inkstone.
I loko o nā makahiki, nui nā mea i hōʻoia i ka pōhaku maoli i lilo i hoʻokahi o nā mea papahele kaulana loa.Loaʻa iā lākou kekahi mau hiʻohiʻona kūpono a kūpono loa i nā mea papahele lumi lumi.ʻO ka Slate, ma ke ʻano he pōhaku maoli, ʻo kona mau hiʻohiʻona i hoʻolilo ʻia ia i mea kūpono no ka papahele hale ʻauʻau.
