itshe le-argillite

I-Argillite yigama elinikezwe amatshe aqinile avele ngenxa yokuphelelwa amanzi emzimbeni, ukucindezela kanye nokuvuselelwa kabusha kobumba. Njengomthetho, itshe alibhekwa njengenani lobucwebe futhi akunakwenzeka ukuthi uthole ubucwebe nalo. Naphezu kweqiniso lokuthi i-mudstone ifana kakhulu ekubunjweni kobumba, isenzima kakhulu futhi imelana nokucwiliswa.

Incazelo

I-mineral ingeye-sedimentary formations, njengoba ukwakheka kwayo kwakhiwe ngenxa yamadwala abhujiswe ngaphansi kwethonya lezimo zemvelo ngaphansi kwethonya lokushisa eliphezulu nokucindezela.

Isakhiwo samaminerali asifani, kodwa siqukethe izingqimba ezihlanganisa isihlabathi, uthuli nobumba. Eqinisweni, naphezu kwalokhu kwakheka, itshe libhekwa njengeliqinile impela. Esikalini se-Mohs, uthole amaphuzu angu-4.

I-shades eyinhloko yohlobo:

• blue-grey;
• mnyama;
• grey-mnyama;
• ukukhanya.

Ukucwebezela kweminerali kunenhlaka, kunosilika. Itshe ngokwalo lintekenteke. Uma ingaphathwa kahle, ingabhidlika kalula.

Amadiphozithi kanye nokumbiwa kwetshe lodaka

Idiphozithi enkulu yetshe itholakala eqenjini leziqhingi eBritish Columbia. Kuyaziwa ukuthi emakhulwini amaningi eminyaka edlule itshe lalisetshenziselwa ukwenziwa kwamathuluzi, izitsha nezinye izitsha, inhloso eyinhloko ukugcinwa kokuphila kanye nokukhishwa kwezinhlinzeko. Ngaphezu kwalokho, izinhlobonhlobo eziyinhloko ze-argillite - i-catlinite - zasetshenziswa abantu baseNdiya baseSioux enyakatho ye-United States naseningizimu yeCanada ukuze benze uphawu lwabo lwamasiko - ipayipi lokuthula, ngosizo lapho kwenziwa izivumelwano zokuthula futhi kwenziwa amasiko. .

Indlela eyinhloko yezimayini ze-argillite ukumba inkwali. Kulokhu, kusetshenziswa imishini evamile yokumba, futhi wonke amaminerali atholakele adluliselwa ngokushesha ukuze ahlaziywe, acwaninge futhi acutshungulwe. Ngaphezu kwalokho, isimo sezulu esomile esinelanga kufanele sibonwe ngesikhathi sokumba, ngoba ekukhuleni okuncane komswakama, amatshe odaka adilika ngokuphelele futhi kumbiwe kulokhu kungenangqondo.

Isicelo

I-Argillite isetshenziswa ezindaweni eziningi, kodwa ikakhulukazi ekwakhiweni. Ngenxa yokuncibilika kwamaminerali ekushiseni okuphezulu, yengezwa ezixubeni ezihlukahlukene ukuze kuthuthukiswe izakhiwo zayo ze-astringent.

Futhi, itshe lisetshenziselwa ukudweba izakhi zokuhlobisa zangaphakathi nangaphandle. Uma wonke umsebenzi wenziwa ngendlela efanele futhi umcabango uboniswa, khona-ke ngenxa yesakhiwo esinezingqimba ezihlukene ze-argillite, ungakha ukubumba okuhle kakhulu kwe-stucco ngendlela yamaphethini, imigqa ebushelelezi, ngisho nezithombe zabantu nezilwane.

I-Argillite nayo idume kakhulu phakathi kwabadwebi nabadwebi. Naphezu kweqiniso lokuthi i-mineral inzima kakhulu ukusebenza nayo (kunzima ukuyicubungula), kuhle kakhulu ekudaleni izithombe eziqoshiwe nemidwebo emithathu-ntathu, evezwe nge-varnish ekugcineni futhi ibukeka imangalisa.
