Rocks Metamorphic

Emvelweni, kukhona izinhlobonhlobo eziningana yamadwala: sedimentary, metamorphic futhi magmatic. Bonke amelela Compound namaminerali ezithile.

Kulesi sihloko sizoxoxa ngokuningiliziwe lokho rocks metamorphic. Thina zichaza izinhlobo, izici nezindlela ukusetshenziswa ezimbonini.

Kodwa ngaphezu kwakho konke, kufanele akutshele ukuthi amatshe ezinjalo. Leligama lisetshenziswa ukuze libhekisele ubunjalo chemical zezakhi okuyinto akhiwa koqweqwe.

Metamorphic amatshe zibangelwa ukuchayeka okushisa aphakeme kanye nengcindezi enamandla phezu namaminerali Lokudabuka magmatic noma sedimentary. Ukwakheka kwamakhemikhali amaminerali akusho nezinguquko eziphawulekayo, kodwa ukuthola ukuthungwa ezintsha kanye nesakhiwo.

namaminerali amaningi metamorphic kukhona oluthambile ezahlukene (khona amahlumela mncane). Lesi sici kubonisa amaminerali ukwakheka indlela (ecindezelekile). namaminerali okunjalo unekhono ukugqekeza ipuleti mncane.

Uma inqubo zokuguqula ezinye amaminerali (metamorphism) kwenzeka ngaphansi isenzo ukushisa mass awayiphazamisi ngesikhathi ukujula engajulile, kulesi simo, amatshe metamorphic kuyodingeka isakhiwo rogovistuyu. Lokhu kwenza hornfelses (biotite, pyroxene, amphibolite) kwakheka ngobumba.

Inqubo metamorphism (ukuguqulwa) okufanele abekeke iyiphi Minerals - igneous, sedimentary noma imvelaphi metamorphic. Noma yimuphi kugucuka wenza emadwaleni esebenzisa recrystallization esimweni okuqinile. I degree of tingucuko namaminerali kokuqala kungaba zahlukahlukene kakhulu, ezisukela ezincane ukulungiswa ukuze izinguquko ezinkulu ukwakheka kanye ukuma wezinsalela zamandulo. Ubunjalo metamorphism ubuye ezahlukene. Kungenzeka kophawu encane kuphela, noma kungenzeka ukuqeda recrystallization we amaminerali.

Zonke amatshe metamorphic kukhona umkhiqizo abazalwa yesibili. Kuye ngezinga of ukuguqulwa, kukhona izinhlobo eziningana inguqulelo namaminerali:

• Oxhumana. It kuvela kusukela Ukungena magma (isingeniso ku ungqimba lomhlaba) kanye nokuxhumana yayo nge inhlabathi. Minerals yalolu hlobo akhiwa ngaphansi kwethonya ingcindezi futhi ukushisa. ezimbiwa phansi okunjalo uyalandisa zemabula, skarn, migmatite. Lesitshalo contact metamorphism bangamaRoma crystalline, omkhulu, futhi saccharoidal slabosloistoe isakhiwo, lapho ukwakheka amaminerali preperpevaet izinguquko eziphawulekayo.
• Regional (ezijulile). inqubo ukuguqulwa okwenzeka ekujuleni okukhulu nge umfutho ophakeme nokuxhumana, izinga lokushisa nasoketshezini. Ukwakheka mineralogical yezimbiwa kuleli cala, ngenza njalo. Breed ezahlukene crystalline oluthambile, isakhiwo ezihambisanayo.
• Dynamo metamorphism. Inqubo ukuguqulwa kwenzeka khona izingqimba zomhlaba ngaphansi kwengcindezi okusezingeni eliphezulu. Esikhathini ezihlukahlukene amaminerali akha indawo eqinile kokuwa futhi emphethweni eziyinkimbinkimbi. Le mivubukulo kukhona mylonites futhi ka-taklazity.

rocks Ngokuvamile metamorphic ukutholakala emvelweni ngesimo imithambo kwezakhi kanye namalensi esibani. Bavame kubuyise owaqalwa amaminerali nesenzakalo, kodwa uma nabo intrusions magma namaminerali ingase irregularly okwenyanga.

namaminerali Metamorphic asetshenziswa emhlabeni wonke njengoba zokuhlobisa, isakhiwo kanye impahla Ornamental (quartzite, imifekethiso, schist, gneiss). Asetshenziswa njengoba izinto zezimboni eluhlaza (asbestos, talc, njll). Imvelo yamadwala metamorphic ngokuvamile etholakala eduze ezifakwa amaminerali, esiyigugu futhi amatshe lulwimi eziyigugu (irubi, Emerald, i-jade, garnet, njll).
