Shale

Ilitye le-Shale lilitye elicolekileyo lentlenga elenziwe ikakhulu ziiminerali zodongwe.. Yenye yezona ntlobo zixhaphakileyo zamatye entlenga kwaye idla ngokufumaneka kwiindawo apho kuye kwakho imfumba enkulu yodaka okanye udongwe., njengakwiibhedi, iidelta zomlambo, neelwandle ezinzulu.

Iifom ze-Shale ezivela ekuqokeleleni iincinci ezincinci, kuquka nodongwe, intlenga, kunye nezinto eziphilayo, ezihlala kwindawo ezolileyo zamanzi kwaye ngokuthe ngcembe ziye zihlangane ngokuhamba kwexesha. I-Shale ihlala ibekwe phantsi, umaleko ngamnye omele ixesha lentlenga, kwaye inokuchongwa ngeempawu zayo zokuqhekeka okanye ukukwazi ukuqhekeza kumaleko amancinci.

I-Shale iqhelekile ukuba ngwevu okanye imnyama ngombala, kodwa inokufumaneka nakwimithunzi emdaka, bomvu, kunye nohlaza. Umbala we-shale uhlala ugqitywa ngumlinganiselo wezinto eziphilayo eziqulethwe, kunye namanqanaba aphezulu ezinto eziphilayo ezikhokelela kwimibala emnyama.

I-Shale inoluhlu lweempawu ezibonakalayo, kuxhomekeke ekubunjweni kwayo kunye nokusingqongileyo ekwakhiwa kuyo. Ngokuqhelekileyo lilitye elithambileyo elinokukrwela ngokulula ngozipho lomnwe, kodwa inokuba nzima kakhulu kwaye yomelele, kuxhomekeke kwisamente kunye nokudibanisa.

I-Shale lilitye elibalulekileyo kuba lihlala liqulethe izixa zeoyile kunye negesi yendalo. Ezi hydrocarbons zivaleleke kwizikhewu ezincinci phakathi kwamasuntswana odongwe lwe-shale kwaye zinokutsalwa ngokuqhekeka kwehydraulic okanye “Ukuqhekeka.” I-Shale iqulethe nezinye iiminerali, njengepyrite, calcite, kunye nequartz, enokusetyenziswa kwizicelo ezahlukeneyo zoshishino.

I-Shale isetyenziswe kwiinjongo ezahlukeneyo kwimbali, kuquka njengesixhobo sokwakha, njengowona mthombo wamafutha, kwaye njengesixhobo sokubonisa ubugcisa. Namhlanje, isetyenziswa ikakhulu kwimithombo yayo yamandla, kodwa ikwasetyenziswa kushishino lokwakha njengento enexabiso eliphantsi lokwakhiwa kweendlela, umgca wokulahla inkunkuma, kunye nezinye izicelo.
