Cov txheej txheem tsim ntawm pob zeb SLATE
Aug 28, 2021
Kev tsim ntawm Slate yog tib yam li sandstone, yog vim lub ntiaj teb' s crust txav, xuab zeb thiab cementation (siliceous khoom, calcium carbonate, av nplaum, hlau oxide, calcium sulfate, thiab lwm yam) tom qab lub sij hawm ntev. ntawm qhov zoo siab compression daim ntawv cog lus tsim ib lub pob zeb sedimentary.Cov xim tam sim no tsuas yog lub teeb ntsuab, dub, lub teeb ntsuab, paj yeeb, xim av xim av, lub teeb grey, daj thiab lwm yam.Lub SLATE tsis yog tsuas yog nplua nuj nyob rau hauv phaj, thiab tawv tawv, xim. thiab luster, tsis tshua muaj dej nqus, tsis muaj hluav taws xob muaj kuab paug, nrog matt, anti-skid, acid thiab alkali tsis kam, refractory txias tsis kam, huab cua tsis kam, zoo tawm tsam thiab lwm yam ntxwv.
Lub ntsiab ntxhia muaj pes tsawg leeg ntawm mica, chlorite, quartz, ib qho me me ntawm pyrite thiab calcite.Lub SLATE tshiab muaj cov xuab zeb ntau dua, ntau calcium thiab pyrite, thiab nyuaj lithology.Cov orebodies yog calcareous silky SLATE thiab zoo silky SLATE, thiab cov thickness ntawm ib txheej yog 1-5cm.
Cov pob zeb me me metamorphic yog tsim los ntawm clayey, silty sedimentary pob zeb los yog nruab nrab-acid tuffaceous pob zeb thiab tuffaceous sediments los ntawm me ntsis metamorphism.Dub los yog greyish dub.Cov lithology yog ntom nrog phaj zoo li cleavage.Muaj feem ntau me me ntawm sericite thiab lwm yam minerals. ntawm lub rooj tsavxwm, kom lub rooj tsavxwm nto me ntsis qhia tau hais tias cov lo lo ntxhuav gloss.Nws tsis muaj qhov pom tseeb recrystallization.Qee cov pob zeb hauv av xws li quartz, sericite thiab chlorite nrog kev faib tsis sib luag tuaj yeem pom nyob rau hauv lub tshuab ntsuas, tab sis feem ntau ntawm lawv yog cryptocrystalline av nplaum ntxhia thiab carbonaceous thiab hlau hmoov.With variable residual qauv thiab speckled qauv.
Lub pob zeb protolith nrog cov qauv zoo li phaj feem ntau yog pob zeb argillaceous, argillaceous siltstone thiab intermediate-acid tuff.SLATE yog cov khoom qis qis ntawm thaj tsam metamorphism, nrog rau qhov kub thiab txias thiab homogeneous siab, uas feem ntau cuam tshuam los ntawm kev ntxhov siab.Cov pob zeb metamorphic feem ntau tsim los ntawm argillaceous thiab silty, thiab SLATE nrog cov qauv ntom ntom thiab SLATE tuaj yeem siv los ua lub tsev pob zeb, ntsiav tshuaj, slab thiab lwm yam ntaub ntawv pob zeb.
Ntau xyoo dhau los, ntau qhov tseeb tau ua pov thawj tias pob zeb ntuj tau dhau los ua ib qho ntawm cov khoom siv hauv pem teb nrov tshaj plaws.Lawv muaj qee yam khoom muaj peev xwm ua rau lawv zoo tagnrho rau chav dej hauv pem teb.SLATE, raws li lub pob zeb ntuj, muaj cov khoom siv hauv tsev uas ua rau chav dej zoo tagnrho. khoom hauv pem teb.
