Ilitye lendalo laseTshayina elikhulu nelimnyama elimnyama eliyi-patio slabs

Amalungu akwislate abangelwa kukukhula kwee-microscopic mica flakes, endaweni yokuqhekeka kwi-sedimentary strata yokuqala.

I-slate yenziwa xa ilitye lodaka, i-shale, okanye ilitye le-felsic igneous lingcwatywa lize lifakwe kumaqondo obushushu aphantsi kunye noxinzelelo.

I-slate incinci kakhulu kwaye ayibonakali emehlweni omntu. I-slate epholisiweyo inomphezulu ongacwebezeliyo kodwa ithambile xa uyichukumisa kwaye yayisetyenziselwa ukwakha iibhodi ezimnyama. Ubuninzi obuncinci be-mica yesilika buyenza i-slate ibonakale ngathi yiglasi yesilika esilika.

I-slate ibonakala ngemibala eyahlukeneyo ngenxa yokwahluka kweempawu zeeminerali kunye neemeko ze-oxidation kwindawo yokuqala ye-sedimentary. Umzekelo, i-black slate yaphuhliswa kwindawo eyayingenawo umoya-mpilo, kodwa i-red slate yaveliswa kwindawo eyayinomoya-mpilo omninzi.

I-slate yenzeka phantsi kwamaqondo obushushu aphantsi kunye noxinzelelo, ngoko ke iifosili zezityalo kunye nezinye izinto ezinobuchule ngokwenene zinokugcinwa.

I-slate imbiwa kwiibhloko ezinkulu kwaye isetyenziselwa iiphaneli zokulawula umbane, ii-worktops, ii-blackboards, kunye nee-floors ngenxa yeempawu zayo ezifana ne-plate, i-elastic, kunye ne-fraying. Ii-slate ezincinci zisetyenziselwa ukwakha uphahla.

Nokuba yintaba ende okanye intlambo enzulu, isixeko esikhulu esixakekileyo okanye ilizwe elinoxolo, ukuma okumangalisayo kwesilayidi kunye nomgangatho oqinileyo kunika inkxaso eqhubekayo kubomi bomntu nomsebenzi wakhe. Le sisilayidi, ubomi obusisiseko kodwa obuqinileyo, ilitye eligcina amabali kunye neenkumbulo zeminyaka eziibhiliyoni.
