Chii Chinonzi Metamorphic Rock?
ziviso
Matombo emetamorphic ndeimwe yemhando nhatu huru dzematombo, pamwe chete nematombo eigneous nesedimentary. Matombo aya anoshanduka zvakanyanya nekuda kwekumanikidzwa kwakanyanya, kupisa kwakanyanya, kana mvura inoshanda nemakemikari, zvichichinja chimiro chemineral, magadzirirwo, uye chimiro chose. Maitiro aya, anonzi metamorphism, anoguma nekuumbwa kwemamwe matombo anoyevedza uye akaomarara anowanikwa pasi pano.
Kuumbwa kweMetamorphic Rocks
Matombo emetamorphic anonyanya kuumbwa mukati megomba rePasi uko tembiricha nekumanikidzwa kwakakwira asi kwete zvekuti zvinozoguma nekunyunguduka. Kuenzana uku kwakakosha pakushandura matombo akambovapo, angave ari igneous, sedimentary, kana kunyange matombo emetamorphic ekare, kuita mafomu matsva emetamorphic.
Mhando dzeMetamorphism
1. Kuchinja kwemaonero evanhu:
Izvi zvinoitika kana matombo aripo akasangana nemagma. Kupisa kwakanyanya kunobva mumagma "kunobika" matombo akapoteredza, zvichikonzera shanduko dzezvicherwa. Nzvimbo inokanganiswa nekupisa uku kwakanyanya inowanzova panzvimbo yakatenderedza kupinda kwemagma, zvichikonzera kuumbwa kwematombo akaita sehornfels.
2. Kuchinja kweMamiriro Ezvinhu Munzvimbo:
Rudzi urwu runowanikwa munzvimbo dzakakura zvikuru, dzinowanzobatanidzwa nemabasa ekuvaka makomo uye mabasa etectonic plate. Kumanikidzwa kukuru uye tembiricha zvinokonzerwa nekuroverana kwetectonic zvinotungamira mukuchinja kwakapararira, zvichigadzira matombo akadai seschist, gneiss, uye slate.
3. Kuchinja kweMamiriro ekunze kwemvura:
Izvi zvinoitika kana mvura inopisa, ine makemikari ichibuda mumakona ematombo aripo kare. Mvura iyi inobatsira pakugadzirwazve kwecrystallization nekuunza maion matsva uye kuunza mineral reactions. Rudzi urwu rwekuchinja kwemamiriro ekunze runowanzoonekwa munzvimbo dziri pakati pegungwa uko mvura yegungwa inosangana neganda regungwa rinopisa, richangobva kugadzirwa.
4. Kuchinja-chinja kwesimba:
Zvichienderana nekumanikidzwa kwakanyanya uye kuchinja kwemavara, kuchinja kwemavara kunowanzoitika munzvimbo dzine matombo ari pasi pekumanikidzwa kwakanyanya asi tembiricha yakaderera. Kuchinja uku kwemavara kunoburitsa matombo ane chitarisiko chakaita semylonite.
Kurongwa kweMetamorphic Rocks
Matombo eMetamorphic anopatsanurwa zvichienderana nekuumbwa kwawo uye kuumbwa kwemaminerari:
1. Matombo Akachinja Matombo:
Matombo aya ane chitarisiko chakaita semachira kana kuti mabhandi. Mienzaniso yakajairika inosanganisira:
– Slate: Yakacheneswa uye inowanzobva mu shale, slate inozivikanwa nekupatsanura kwayo kwakanaka.
– Schist: Dombo iri rine zvirimwa zviri pakati nepakati kusvika pakaoma rine mashizha akakura uye rinowanzova nemaminerari akadai semica.
– Gneiss: Ine mabhandi ezvicherwa akareruka neakasviba anochinjana, gneiss ine ganda rakakora uye inowanzo umbwa mumamiriro ekumanikidzwa kwakanyanya uye tembiricha yakakwira.
2. Matombo Asina Foliated Metamorphic:
Matombo aya haaratidzi chitarisiko chakaita zvidimbu kana kuti mabhandi. Mienzaniso inokosha inosanganisira:
– Marble: Yakagadzirwa nedombo re limestone, marble inokosheswa nekuda kwekunaka kwayo uye inoshandiswa zvakanyanya mukuveza nekuvaka.
– Quartzite: Yakabva padombo rejecha rine quartz, quartzite idombo rakaoma, risina mashizha.
– Hornfels: Kazhinji inoumbwa kuburikidza nekubatana, hornfels dzine magadzirirwo akatsetseka uye matombo akasimba uye anogara kwenguva refu.
Metamorphic Maitiro
Maitiro makuru anobatanidzwa mukuumbwa kwematombo emetamorphic anosanganisira:
1. Kudzokorodza:
Maitiro aya anosanganisira kuumbwa kwezvicherwa zvitsva zvinogara zvakanaka kana tembiricha yakwira uye kumanikidzwa. Semuenzaniso, kudzokororwa kwedombo remarara kunotungamira pakuumbwa kwedombo remabhuru.
2. Kuchinja kwechikamu:
Zvicherwa zviripo zvinogona kushanduka kuita mapolymorph akasiyana-siyana akasimba zvakanyanya kana paine kumanikidzwa kwakanyanya uye mamiriro ekupisa. Muenzaniso unokosha ndiko kushandurwa kwegraphite kuita dhaimani.
3. Mhinduro Yekumanikidza:
Kana zvanyatsoiswa muchimiro chekumanikidzwa, zvicherwa zvinogona kunyungudika panzvimbo dzine kumanikidzwa kwakanyanya uye zvinodonha munzvimbo dzine kumanikidzwa kwakaderera. Maitiro aya anobatsira mukukura kwemaumbirwo emashizha.
4. Kuchinja kwepurasitiki:
Matombo anomanikidzwa zvakanyanya anogona kuchinja chimiro chepurasitiki. Maitiro aya anochinja chimiro uye kurongeka kwemaminerari pasina kutsemuka kana kupwanya dombo, zvichibatsira mukuita kuti matombo awedzere kuumbwa sematombo emhando ye "metamorphic" akadai se "schists" ne "gneisses".
Kukosha Kweupfumi
Matombo emetamorphic ane kukosha kukuru kwehupfumi:
1. Kuvaka uye Kushongedza:
Matombo ematombo nematombo ematombo anoshandiswa zvakanyanya mukuvaka. Kuyevedza kwematombo aya uye hunhu hwawo zvinoita kuti ave sarudzo dzakakurumbira pakuisa countertops, pasi, uye padenga.
2. Kushandiswa Kwemaindasitiri:
Mamwe matombo asina mashizha akachinja-chinja, akadai sequartzite nehornfels, ane kuomarara kunoshamisa uye anodzivirira kudonha kwemvura, zvichiita kuti akwanise kushandiswa sematombo akapwanyika mukuvaka migwagwa uye senzira yekudzivirira matombo kubva muzvitima.
3. Matombo Anokosha:
Kuchinja-chinja kwezvicherwa kunogona kugadzira matombo anokosha. Semuenzaniso, garnet, iyo inowanzo umbwa mumamiriro ezvinhu akachinja, idombo rinokosha, uye kuumbwa kwemadhaimani kubva kugraphite muenzaniso unoratidza kushanduka kwezvicherwa nekuda kwemamiriro ezvinhu akaipisisa.
Matombo Akachinja-chinja Munhoroondo Yepasi
Matombo emetamorphic anokosha kune vanoongorora geology sezvo achipa mukana wekuona mamiriro emukati meNyika uye maitiro e tectonic kuburikidza nenguva ye geological. Nekudzidza matombo aya, vanoongorora geology vanogona kufungidzira mamiriro ekupisa, mamiriro ekumanikidzwa, uye kunyange makemikari eganda repasi uye mantle panguva dzakasiyana-siyana.
Matombo akaita semagranulite ekare nemagneisses anowanikwa muzvidziviriro zvekare zvepasi pano anopa ruzivo rwekuumbwa nekugadzikana kweganda rekutanga rekondinendi. Kudzidza kwavo kwakabatsira kugadzirazve mamodheru emakondinendi ekare uye kunzwisisa maitiro etectonic akaumba nhoroondo ye geology yepasi redu.
mhedziso
Matombo emetamorphic, ane mavambo akasiyana-siyana, magadzirirwo, uye maumbirwo awo, anotaura nyaya inonakidza yekushanduka pasi pemamiriro ekushanduka kwePasi. Kungave kuburikidza nekupisa kwakanyanya kwe contact metamorphism, masimba ekumanikidza e regional metamorphism, kana kemikari ye hydrothermal fluids, matombo aya anogara achichinja, achiratidza musimboti wekuti shanduko chinhu chakakosha mu geological processes. Kukosha kwawo mune zvehupfumi uye data renhoroondo raanopa kunoita kuti ave anokosha kune vese indasitiri nesainzi, zvichiratidza kukosha kwawo mukunzwisisa kwedu Pasi.
