Slate ingagwiritsidwe ntchito padenga, pansi, minda ndi malo ena, komanso mwala wabwino wokongoletsera, mwala wachilengedwe ndi wosiyanasiyana, slate ndi chiyani?Anthu ambiri sadziwa zambiri za mwala wotere.Kodi slate inayamba bwanji?Osadandaula.Tiye tikambirane.Tiyeni tiwone.

Kodi slate ndi chiyani?

Slate ndi mtundu wa thanthwe la metamorphic lomwe lili ndi slate kapangidwe kake komanso kopanda kukonzanso.Mwala woyambirira ndi wa argillaceous, silty kapena osalowerera ndale, womwe ukhoza kuchotsedwa kukhala mapepala owonda motsatira slate.Amapangidwa ndi metamorphism pang'ono ya clayey, silty sedimentary rocks, intermediate-acid tuffaceous rocks ndi sedimentary tuffaceous rocks.
Chifukwa cha kuchepa kwa madzi m'thupi, kuuma kwa thanthwe loyambirira kumakulitsidwa, koma kapangidwe kake ka mchere sikamayambiranso.Ili ndi mawonekedwe a metamorphic ndi mawonekedwe a metamorphic, ndipo mawonekedwe ake ndi owuma komanso obisika.Ma mineral particles ndi abwino kwambiri, omwe ndi ovuta kusiyanitsa ndi maso amaliseche.Nthawi zambiri pamakhala sericite pang'ono ndi mchere wina pamwamba pa mbale, zomwe zimapangitsa pamwamba pa mbale kukhala silky pang'ono.Slate imatha kutchulidwa mwatsatanetsatane malinga ndi zonyansa zamitundu yosiyanasiyana, monga slate yakuda ya carbonaceous ndi gray green calcareous slate.Mu otsika grade matenthedwe kukhudzana metamorphism, osaya metamorphic miyala yokhala ndi mawanga ndi mbale zomangira amatha kupangidwa, omwe amatchedwa "miyala yamawanga".Slate ingagwiritsidwe ntchito ngati zipangizo zomangira ndi zokongoletsera.Kalekale, ankagwiritsidwa ntchito ngati matailosi m’madera odzala ndi masileti.

Kodi slate idapangidwa bwanji?

Slate, ngati sandstone, ndi thanthwe la sedimentary lomwe limapangidwa ndi kusuntha kwa dziko lapansi ndi kukanikizana ndi kumangirira mchenga ndi simenti (siliceous matter, calcium carbonate, dongo, iron oxide, calcium sulfate, etc.) pansi pa nthawi yayitali kwambiri. kupanikizika.Pakalipano, mitundu yayikulu ndi yowala buluu, yakuda, yobiriwira, pinki, yofiirira, imvi yowala, yachikasu ndi zina zotero.Slate si wolemera mu kapangidwe, komanso molimba, mtundu wokongola, mayamwidwe otsika madzi, palibe kuipitsidwa cheza, ndi Mat, odana skid, asidi ndi alkali kukana, moto ndi kuzizira kukana, weathering kukana, crackability wabwino ndi makhalidwe ena.

Zomwe zimapangidwa ndi mchere zimakhala makamaka mica, zotsatiridwa ndi chlorite, quartz, pyrite pang'ono ndi calcite.Sileti yatsopanoyi imakhala ndi mchenga wambiri, calcium ndi pyrite wochulukirapo, komanso hard lithology.Matupi a ore ndi calcareous sericite ndi silty sericite yokhala ndi makulidwe amodzi a 1-5 cm.
Miyala yozama ya metamorphic imapangidwa ndi kusintha pang'ono kwa clayey, silty sedimentary rocks, intermediate-acid tuffaceous rocks ndi sedimentary tuffaceous rocks.Wakuda kapena imvi-wakuda.The lithology ndi yaying'ono ndipo mbale cleavage anapangidwa bwino.Nthawi zambiri pamakhala sericite pang'ono ndi mchere wina pamwamba pa mbale, zomwe zimapangitsa pamwamba pa mbale kukhala silky pang'ono.Panalibe recrystallization zoonekeratu.Mwachisawawa, njere zina zamchere, monga quartz, sericite ndi chlorite, zimagawidwa mosagwirizana, koma zambiri ndi mchere wadongo wa cryptocrystalline ndi ufa wa carbonaceous ndi chitsulo.Ili ndi kamangidwe kake komanso kamangidwe ka mawanga.
Miyala yoyambirira yokhala ndi mbale ndi miyala ya argillaceous, argillaceous siltstone ndi tuff yapakati-acid.Slate ndi chinthu chochepa kwambiri cha metamorphism ya m'madera, ndipo kutentha kwake ndi kupanikizika kwa yunifolomu sipamwamba, zomwe zimakhudzidwa makamaka ndi kupsinjika maganizo.The lamellar cleavage metamorphic miyala ndi argillaceous ndi silty zigawo zikuluzikulu ndi zigawo argillaceous ndi silty monga zigawo zikuluzikulu angagwiritsidwe ntchito ngati kumanga mwala, mwala ndi inkstone.
Kwa zaka zambiri, mfundo zambiri zatsimikizira kuti miyala yachilengedwe yakhala imodzi mwa zipangizo zotchuka kwambiri zapansi.Ali ndi makhalidwe ena omwe angathe ndipo ndi abwino kwambiri kwa zipangizo zapansi za bafa.Slate, monga mwala wachilengedwe, mawonekedwe ake achilengedwe amapangitsa kukhala chinthu chabwino kwambiri chapansi pa bafa.
