I-slate ingasetshenziswa ophahleni, phansi, izingadi nakwezinye izindawo, kodwa futhi itshe elihle lokuhlobisa, itshe lemvelo liyizinhlobonhlobo, yini i-slate?Abantu abaningi abazi okuningi ngalolu hlobo lwamatshe.I-slate yaba khona kanjani?Ungakhathazeki.Ake sixoxe ngakho.Ake sibheke.

Yini isileyithi?

I-Slate iwuhlobo lwetshe le-metamorphic elinesakhiwo se-slate futhi alikho ukubuyiswa kabusha.Itshe loqobo liyi-argillaceous, i-silty noma i-neutral tuff, engahlutshulwa ibe amashidi azacile ngokuhambisana nesileyithi.Yakheka i-metamorphism encane ye-clayey, amatshe e-sedimentary ayi-silty, amadwala aphakathi-asidi a-tuffaceous kanye namatshe e-sedimentary tuffaceous.
Ngenxa yokuphelelwa amanzi emzimbeni, ubulukhuni betshe lokuqala buyathuthukiswa, kodwa ukwakheka kwamaminerali empeleni akubuyeli kabusha.Inesakhiwo se-metamorphic kanye nesakhiwo se-metamorphic, futhi ukubukeka kwayo kuminyene futhi kufihliwe i-crystallization.Izinhlayiya zamaminerali zihle kakhulu, okunzima ukuhlukanisa ngamehlo anqunu.Ngokuvamile kuba nenani elincane le-sericite namanye amaminerali ebusweni bepuleti, okwenza ingaphezulu lepuleti libe nosilika kancane.Isileyithi ngokuvamile singaqanjwa ngokuningiliziwe ngokuya ngokungcola kwemibala ehlukene, njengesileti esimnyama esinekhabhoni kanye nesileyiti esimpunga esiluhlaza.Ku-metamorphism yezinga eliphansi lokuxhumana okushisayo, amatshe e-metamorphic angajulile anamabala kanye nezinhlaka zamapuleti angakhiwa, avame ukubizwa ngokuthi "amadwala anamabala".I-slate ingasetshenziswa njengezinto zokwakha nezinto zokuhlobisa.Ezikhathini zasendulo, yayivame ukusetshenziswa njengothayela ezindaweni ezinothe ngezileyithi.

Sakheka kanjani isileyithi?

I-Slate, njenge-sandstone, idwala le-sedimentary elakhiwe ukunyakaza kwe-crustal yomhlaba kanye nokucindezelwa nokuhlanganiswa kwezinhlamvu zesihlabathi nosimende (i-siliceous matter, i-calcium carbonate, ubumba, i-iron oxide, i-calcium sulfate, njll.) ngaphansi kobukhulu besikhathi eside. ingcindezi.Njengamanje, imibala eyinhloko iluhlaza okwesibhakabhaka, omnyama, oluhlaza okotshani, opinki, onsundu, ompunga okhanyayo, ophuzi njalo njalo.I-Slate ayicebile kuphela ekuthunjweni, kodwa futhi nombala oqinile, omuhle, ukumuncwa kwamanzi aphansi, akukho ukungcoliswa kwemisebe, ne-matt, i-anti-skid, ukumelana ne-asidi ne-alkali, ukumelana nomlilo nokubanda, ukumelana nesimo sezulu, ukuqhekeka okuhle nezinye izici.

Ukwakhiwa kwamaminerali ikakhulukazi i-mica, kulandelwa i-chlorite, i-quartz, inani elincane le-pyrite ne-calcite.I-slate entsha inokuqukethwe kwesihlabathi esiphezulu, i-calcium ne-pyrite eningi, kanye ne-hard lithology.Imizimba ye-ore iyi-calcareous sericite kanye ne-sericite eyi-silty enogqinsi olulodwa luka-1-5 cm.
Amatshe e-metamorphic angajulile akhiwa yi-metamorphism encane ye-clayey, amatshe e-sedimentary ayi-silty, amadwala aphakathi-asidi a-tuffaceous kanye namadwala angama-sedimentary tuffaceous.Mnyama noma grey-mnyama.I-lithology ihlangene futhi i-plate cleavage ithuthukiswe kahle.Ngokuvamile kuba nenani elincane le-sericite namanye amaminerali ebusweni bepuleti, okwenza ingaphezulu lepuleti libe nosilika kancane.Kwakungekho ukuphindaphinda okusobala.Ngokwe-Microscopically, ezinye izinhlamvu zamaminerali, njenge-quartz, i-sericite ne-chlorite, zisakazwa ngokungalingani, kodwa eziningi zazo zingamaminerali obumba we-cryptocrystalline kanye nezimpushana ze-carbonaceous nezinsimbi.Inesakhiwo esingasasebenzi kanye nesakhiwo esinamabala.
Amatshe ayisisekelo anesakhiwo sepuleti ikakhulukazi amadwala argillaceous, i-argillaceous siltstone kanye ne-intermediate-acid tuff.I-Slate iwumkhiqizo wezinga eliphansi le-metamorphism yesifunda, futhi izinga lokushisa layo nokucindezela okufanayo akuphakeme, okuthinteka kakhulu ukucindezeleka.I-lamellar cleavage metamorphic rocks enezingxenye ze-argillaceous kanye ne-silty njengezingxenye eziyinhloko kanye nezingxenye ze-argillaceous kanye ne-silty njengezingxenye eziyinhloko zingasetshenziswa njengetshe lokwakha, i-stele kanye ne-inkstone.
Phakathi neminyaka edlule, amaqiniso amaningi afakazele ukuthi itshe lemvelo liye laba enye yezinto ezithandwa kakhulu phansi.Zinezici ezithile ezingaba khona futhi zifaneleka kakhulu ezintweni zokugezela zaphansi.I-Slate, njengetshe lemvelo, izici zayo zemvelo ziyenza ibe yinto efanelekile yaphansi yokugezela.
