Slate waxaa loo isticmaali karaa saqafka, sagxadaha, jardiinooyinka iyo meelo kale, laakiin sidoo kale dhagax qurxin wanaagsan, dhagax dabiici ah waa noocyo kala duwan, waa maxay slate?Dad badan ayaan wax badan ka ogeyn dhagaxa noocaan ah.Sidee ku timid slate?Ha welwelin.Aan ka hadalno.Aan eegno.

Waa maxay slate?

Slate waa nooc ka mid ah dhagaxa metamorphic ah oo leh qaab dhismeed oo aan lahayn dib u celin.Dhagaxa asalka ah waa argillaceous, silty ama tuff dhexdhexaad ah, kaas oo lagu dhejin karo go'yo khafiif ah oo u socda jihada saleebka.Waxa lagu sameeyay metamorphism yar oo dhoobo ah, dhagaxyo sedimentary oo silty ah, dhagaxyo tufaceous acid dhexdhexaad ah iyo dhagxaan tufaceous sedimentary.
Fuuqbaxa awgeed, engegnaanta dhagaxa asalka ah waa la wanaajiyey, laakiin ka kooban macdanta asal ahaan dib uma soo celiso.Waxay leedahay qaab-dhismeed metamorphic ah iyo qaab-dhismeed metamorphic ah, muuqaalkeeduna waa mid cufan oo qarsoodi ah.Qaybaha macdanta ayaa ah kuwo aad u fiican, taas oo ay adag tahay in lagu kala saaro indho qaawan.Inta badan waxaa jira qadar yar oo sericite ah iyo macdano kale oo ku yaal dusha sare ee saxanka, taas oo ka dhigaysa dusha sare ee saxanka wax yar.Slate guud ahaan si faahfaahsan ayaa loo magacaabi karaa iyadoo loo eegayo wasakhda midabyada kala duwan, sida saleebka kaarboonka madow ee madow iyo caleenta calcareous cagaarka ah.Metamorphism-ka xidhiidhka kulaylka heer-hoose, dhagaxyo metamorphic-gaaban oo leh qaab-dhismeedyo iyo qaab-dhismeed saxan ah ayaa la samayn karaa, oo caadi ahaan loo yaqaan "dhagaxa la arkay".Slate waxaa loo isticmaali karaa sida qalabka dhismaha iyo alaabta qurxinta.Waqtiyadii hore, waxa caadi ahaan loo isticmaali jiray sidii tile meelaha qani ku ah saleebka.

Sidee buu u samaysmay slate?

Slate, sida sandstone, waa dhagax sedimentary ah oo ay sameysteen dhaqdhaqaaqa qolof ah ee dhulka iyo isku dhafka iyo isku xidhka badarka ciidda iyo sibidhka (waxyaabaha siliceous, calcium carbonate, dhoobo, oksijiinta birta, calcium sulfate, iwm) hoos yimaada muddada dheer ee weyn. cadaadis.Waqtigan xaadirka ah, midabada ugu muhiimsan waa buluug khafiif ah, madow, cagaar khafiif ah, casaan, bunni, cawl fudud, jaalle iyo wixii la mid ah.Slate ma aha oo kaliya hodan ku ah texture, laakiin sidoo kale adag, midabka xarrago leh, nuugista biyaha hoose, aan wasakhda shucaaca, oo leh matt, anti-skid, caabbinta acid iyo alkali, dab iyo qabow iska caabin, caabbinta cimilada, crackability wanaagsan iyo sifooyin kale.

Halabuurka macdanta inta badan waa mica, oo ay ku xigto chlorite, quartz, qadar yar oo pyrite ah iyo calcite.Slate cusub waxa uu leeyahay maaddo ciid sare leh, kalsiyum iyo pyrite badan, iyo lithology adag.Jidadka macdanta waa sericite calcareous iyo silty sericite oo leh hal lakab oo dhumucdiisuna tahay 1-5 cm.
Dhagaxyada metamorphic-ga-gacmeedka ah waxaa lagu sameeyay metamorphism yar oo dhoobo ah, dhagaxyo sedimentary oo silty ah, dhagaxyo tufaceous acid dhexdhexaad ah iyo dhagxaan tufaceous sedimentary.Madow ama cawl-madow.Lithology-ga waa mid is haysta oo kala goynta saxanka ayaa si fiican u horumaray.Inta badan waxaa jira qadar yar oo sericite ah iyo macdano kale oo ku yaal dusha sare ee saxanka, taas oo ka dhigaysa dusha sare ee saxanka wax yar.Ma jirin wax muuqda oo recystallization ah.Microscopically, qaar ka mid ah miraha macdanta, sida quartz, sericite iyo chlorite, ayaa si siman loo qaybiyay, laakiin intooda badan waa macdanta dhoobada cryptocrystalline iyo kaarboonka iyo budada birta.Waxay leedahay qaab dhismeed aan badnayn iyo qaab-dhismeed muuqda.
Dhagaxyada asaasiga ah ee qaab dhismeedka saxanku waxay u badan yihiin dhagaxyada argillaceous, siltstone argillaceous iyo tuff acid dhexdhexaad ah.Slate waa wax soo saar hoose oo metamorphism gobolka ah, iyo heerkulkeeda iyo cadaadiska labbiska ah maaha mid sarreeya, kuwaas oo inta badan ay saamayso walbahaarka.Dhagaxyada metamorphic ee lamellar waxay kala jajabaan dhagaxyo isku dhafan oo leh qaybo argillaceous ah iyo qaybo silty ah oo ah qaybaha ugu muhiimsan iyo qaybaha argillaceous iyo silty sida qaybaha ugu muhiimsan ee loo isticmaali karo dhagax dhisme, stele iyo khad.
Sanado badan, xaqiiqooyin badan ayaa caddeeyey in dhagaxa dabiiciga ah uu noqday mid ka mid ah qalabka ugu caansan ee dabaqa.Waxay leeyihiin astaamo suurtagal ah waxayna aad ugu habboon yihiin qalabka sagxada musqusha.Slate, sida dhagax dabiici ah, sifooyinkeeda asalka ah ayaa ka dhigaya wax ku habboon sagxada musqusha.
