Chii chinonzi slate?

Slate imhando yedombo remetamorphic ine slate chimiro uye isina recrystallization.Dombo rekutanga ndeye argillaceous, silty kana neutral tuff, iyo inogona kubviswa kuita matete masheets achitevedza nzira yeslate.Inoumbwa nediki metamorphism ye clayey, silty sedimentary matombo, epakati-asidhi tuffaceous matombo uye sedimentary tuffaceous matombo.
Nekuda kwekupera mvura mumuviri, kuoma kwedombo rekutanga kunowedzerwa, asi iyo mineral composition haigadzirisike zvakare.Iyo ine metamorphic chimiro uye metamorphic chimiro, uye chitarisiko chayo chakaonda uye chakavanzika crystallization.Iyo mineral particles yakanaka kwazvo, iyo yakaoma kusiyanisa nemeso asina kupfeka.Pane kazhinji kacho kadiki sericite uye mamwe maminera pamusoro peplate, izvo zvinoita kuti nzvimbo yeplate iite silky.Slate inogona kazhinji kupihwa zita rakadzama zvinoenderana nekusachena kwemavara akasiyana, senge black carbonaceous slate uye grey green calcareous slate.Mune yakaderera-giredhi thermal kusangana metamorphism, isina kudzika metamorphic matombo ane mavara uye mapuratifomu anogona kuumbwa, anowanzo kunzi "spotted matombo".Slate inogona kushandiswa sezvivakwa zvekuvaka uye zvekushongedza zvinhu.Munguva dzekare, yaiwanzoshandiswa sematairi munzvimbo dzakapfuma mune slate.

Slate yakaumbwa sei?

Slate, sejecha, idombo re sedimentary rakaumbwa nekufamba kwepasi uye kudzvanywa uye kusungirirwa kwejecha tsanga nemasimende (siliceous matter, calcium carbonate, ivhu, iron oxide, calcium sulfate, nezvimwewo) pasi pehukuru hwenguva refu. pressure.Parizvino, iwo mavara makuru ndeye bhuruu, dema, girini, pink, brown, grey grey, yero uye zvichingodaro.Slate haina kupfuma mukugadzirwa chete, asiwo yakaoma, inoyevedza ruvara, kunyura kwemvura yakadzika, hapana kusvibiswa kwemwaranzi, ine matt, anti-skid, asidhi uye alkali kuramba, moto uye kutonhora kuramba, kusamira kwemamiriro ekunze, kuputika kwakanaka uye humwe hunhu.

Mucherechedzo weminerari unonyanya kuve mica, inoteverwa neklorite, quartz, shoma shoma yepyrite uye calcite.Iyo slate nyowani ine yakakwira jecha yemukati, yakawanda calcium uye pyrite, uye yakaoma lithology.Miviri ye ore ndeye calcareous sericite uye silty sericite ine imwe layer gobvu ye 1-5 cm.
Iwo asina kudzika metamorphic matombo anoumbwa nediki metamorphism ye clayey, silty sedimentary matombo, epakati-asidhi tuffaceous matombo uye sedimentary tuffaceous matombo.Dema kana grey-dema.Iyo lithology i compact uye plate cleavage yakagadziridzwa zvakanaka.Pane kazhinji kacho kadiki sericite uye mamwe maminera pamusoro peplate, izvo zvinoita kuti nzvimbo yeplate iite silky.Ikoko kwakanga kusina recrystallization iri pachena.Microscopically, mamwe maminerari zviyo, senge quartz, sericite uye chlorite, akagoverwa zvisina kuenzana, asi mazhinji acho ari cryptocrystalline clay minerals uye carbonaceous uye iron powders.Iyo ine dhizaini dhizaini uye ine mavara maitiro.
Matombo ekutanga ane dhizaini dhizaini anonyanya kuve argillaceous matombo, argillaceous siltstone uye yepakati-asidhi tuff.Slate chinhu chakaderera-giredhi chigadzirwa chedunhu metamorphism, uye tembiricha yayo uye yunifomu yekumanikidza haina kukwirira, iyo inonyanya kukanganiswa nekushushikana.Iyo lamellar cleavage metamorphic matombo ane argillaceous uye silty zvikamu sechinhu chikuru uye argillaceous uye silty zvikamu sezvikamu zvikuru zvinogona kushandiswa sedombo rekuvaka, stele uye inkstone.
Kwemakore akawanda, chokwadi chakawanda chakaratidza kuti dombo rechisikigo rakava chimwe chezvinhu zvakakurumbira zvepasi.Vane mamwe maitiro anogona uye anonyatsokodzera kune yekugezera pasi zvinhu.Slate, sedombo rechisikigo, hunhu hwayo hunoita kuti ive yakanaka yekugezera pasi zvinhu.
