Icyapa gishobora gukoreshwa hejuru yinzu, hasi, mu busitani nahandi, ariko kandi ibuye ryiza ryo gushushanya, ibuye karemano ni ubwoko butandukanye, ikibaho ni iki? Abantu benshi ntibazi byinshi kuri ubu bwoko bwamabuye. Urupapuro rwabayeho gute? Ntugire ikibazo. Reka tubiganireho. Reka turebe.

Urupapuro ni iki?

Slate ni ubwoko bwa metamorphic urutare rufite imiterere ya plate kandi nta restallisation. Urutare rwumwimerere ni arillaceous, silty cyangwa neutre tuff, ishobora kwamburwa mumabati yoroheje yerekeza kumurongo. Ihindurwa na metamorphism nkeya yibumba, amabuye ya silitike, amabuye ya acide hagati ya acide na tuffaceous amabuye.
Kubera umwuma, ubukana bwurutare rwumwimerere buratera imbere, ariko imyunyu ngugu ntisubirwamo. Ifite imiterere ya metamorphic nuburyo bwa metamorphic, kandi isura yayo ni yuzuye kandi ihishe kristu. Ibice bya minerval nibyiza cyane, biragoye kubitandukanya namaso. Habaho ubwinshi bwa sericite hamwe nandi mabuye y'agaciro hejuru yisahani, bigatuma ubuso bwisahani buba bworoshye. Icyapa gishobora kwitwa muburyo burambuye ukurikije amabara atandukanye, nkibara ryirabura rya karubone hamwe nicyatsi kibisi kibisi. Mugihe cyo hasi yubushyuhe bwo guhuza metamorphism, amabuye maremare ya metamorphic afite ibibara hamwe nibisahani birashobora gushingwa, bakunze kwita "urutare ruboneka". Icyapa kirashobora gukoreshwa nkibikoresho byo kubaka nibikoresho byo gushushanya. Mubihe bya kera, wasangaga byakoreshwaga nka tile mubice bikungahaye.

Urupapuro rwakozwe gute?

Slate, nkibuye ryumusenyi, ni urutare rwimitsi rwakozwe nigitambambuga cyisi hamwe no guhuza no guhuza ibinyampeke na sima (ibintu bya silice, calcium karubone, ibumba, okiside ya fer, calcium sulfate, nibindi) mugihe kinini kinini igitutu. Kugeza ubu, amabara nyamukuru ni ubururu bwerurutse, umukara, icyatsi kibisi, umutuku, umutuku, imvi, umuhondo n'ibindi. Slate ntabwo ikungahaye gusa ku miterere, ariko kandi irakomeye, ibara ryiza, kwinjiza amazi make, nta kwanduza imirasire, hamwe na matt, anti-skid, aside na alkali birwanya, umuriro hamwe nubukonje bukabije, guhangana nikirere, gucika neza nibindi biranga.

Ibigize imyunyu ngugu ahanini ni mika, bigakurikirwa na chlorite, quartz, umubare muto wa pyrite na calcite. Urupapuro rushya rufite umucanga mwinshi, calcium nyinshi na pyrite, hamwe na lithologiya ikomeye. Imibiri yubutare ni serisite ya calcare na silicite ya silicite hamwe nuburebure bwa cm 1-5.
Urutare ruto rutagira ingano rugizwe na metamorphism nkeya y'ibumba, amabuye ya silitike, amabuye ya acide hagati ya acide na acide ya tuffaceous. Umukara cyangwa imvi-umukara. Lithologiya irahuzagurika kandi isahani ya plaque yateye imbere neza. Habaho ubwinshi bwa sericite hamwe nandi mabuye y'agaciro hejuru yisahani, bigatuma ubuso bwisahani buba bworoshye. Nta byongeye kugaragara. Mikorosikopi, ibinyampeke bimwe na bimwe, nka quartz, sericite na chlorite, ntibisaranganywa, ariko ibyinshi muri byo ni amabuye y'agaciro ya cryptocrystalline hamwe nifu ya karubone na fer. Ifite imiterere irenze kandi igaragara.
Urutare rwibanze rufite plaque ni urutare rwinshi, arillaceous siltstone hamwe na aside iringaniye. Slate nigicuruzwa cyo mu rwego rwo hasi cya metamorphism yo mu karere, kandi ubushyuhe bwacyo hamwe nigitutu kimwe ntabwo kiri hejuru, byibasiwe cyane nihungabana. Lamellar clavage metamorphic urutare hamwe na argillaceous na silty nkibice byingenzi hamwe na argillaceous na silty nkibice byingenzi bishobora gukoreshwa nko kubaka amabuye, stele na wino.
Mu myaka yashize, ibintu byinshi byagaragaje ko ibuye risanzwe ryabaye kimwe mubikoresho bizwi cyane. Bafite bimwe mubishobora kuranga kandi birakwiriye cyane mubikoresho byo mu bwiherero. Icyapa, nkibuye risanzwe, ibiranga biranga bituma habaho ubwiherero bwiza.
