Dhagaxyada Metamorphic

In dabiiciga ah, waxaa jira noocyo dhowr ah oo dhagaxyo ah, ku aasan, metamorphic iyo magmatic. Dhamaan iyaga ka mid ah wakiil macdan gaar ah xarunta.

In this article waxaan ka hadli doonaa si faahfaahsan waxa dhagaxyada metamorphic. Waxaan ku tilmaami noocyada, sifooyinka iyo hababka loo isticmaalo warshadaha.

Laakiin wax kasta ka sarreeya, waa in aad u sheegto in dhagaxyada sida. Ereygan waxaa loo adeegsaday tilmaamista nooca kiimikada xeryahooda, kuwaas oo loo sameeyay in qolof ah.

Metamorphic dhagaxyada yihiin natiijada gaadhista heerkulka sare iyo cadaadis xoog leh oo ku saabsan macdan ka soo jeedo magmatic ama ku aasan. Walxaha kiimikada ee macdanta ma mari isbedel la taaban karo, laakiin waxa ay u bartaan texture cusub iyo qaab-dhismeedka.

macdano badan oo metamorphic waa Shale oo kala duwan (joogitaanka geedo khafiif ah). dabeecad Tani waxay muujinaysaa habka formation macdanta (cadaadis). macdanta noocan oo kale ah awood u leeyihiin in ay jebiyaan galay waslad khafiifa.

Haddii habka of diinta qaar ka mid ah macdanaha kale (metamorphism) dhacdaa hoos tallaabada kulaylka mass adigoo at qoto dheer gacmeed, kiiskan, dhagaxyada metamorphic yeelan doonaa qaab-dhismeedka rogovistuyu. Tani waxa uu tusaale by hornfelses (biotite, pyroxene, amphibolite) sameeyay dhoobo.

Geedi socodka ah ee metamorphism (Isbadal) yaabaa in lagu qaado wax Macdanta - igneous, ku aasan ama asal metamorphic. transformations kasta oo dhagaxyada dhexdooda taasi oo ka recrystallization ee gobolka adag. heerka uu isbadal ka mid ah macdanta laga bilaabo karaan kuwo aad u kala duwan, laga bilaabo yar beddelka inuu isbedel badan ee Halabuurka iyo qaabka lafo ah. dabiiciga ah ee metamorphism sidoo kale waa ka duwan yahay. Waxa uu dhici karaa oo keli ah shaabadda yar, ama buuxin kartaa recrystallization ee macdanta.

All dhagaxyada metamorphic waa wax ka muuqo sare. Iyadoo ku xiran heerka uu diinta, waxaa jira dhawr nooc oo macdanta kala guurka:

• xiriirka. Waxaa soo baxdo ka galidda ee magma (sal-dhigida ee qolof Dhulka) iyo in ay is dhexgalka korsiiya ah. Macdanta noocan ah loo sameeyay sarkhaansan yihiin cadaadis iyo kulaylkii. lafo noocan oo kale ah la xidhiidho marmar ah, skarn, migmatite. Species metamorphism xiriir yihiin inta badan crystalline, weyn, iyo qaab-dhismeedka slabosloistoe saccharoidal, kuna waari dhexdeeda ka kooban macdanta preperpevaet isbedel la taaban karo.
• Regional (qoto dheer). habka badalaada qaadataa meel at moolka la kar dhexgalka, heerkulka iyo cabitaan. Halabuurka The mineralogical macdanta ee kiiskan, waxaan had iyo jeer ma sameeyaan. Nooc Shale crystalline kala duwan, qaab-dhismeedka dhagan.
• Dynamo metamorphism. habka Isbadal ayaa ka dhacdaa taarikada tectonic cadaadis sare. In kala duwan oo ka mid ah macdanta sameeyay aaga xoogan oo burbur iyo laalaabka adag. fossils Kuwanu waa mylonites iyo ka-taklazity.

dhagaxyada Sida caadiga ah waxaa laga helaa metamorphic ee dabiiciga ah ee foomka of xididdada, ayaa ceegaagta iyo lenses. Waxay inta badan hayn qaab asalka ah ee dhacdo macdanta, laakiin markii xiriir la macdanta loo calaanjin magma laga yaabaa caadi ahayn la qaabeeya.

macdanta Metamorphic waxaa dunida oo dhan loo isticmaalaa sida madaxtooyada, dhismaha iyo qalabka ornamental (quartzite, marmar, schist, gneiss). Waxaa sidoo kale loo isticmaalaa sida qalabka warshadaha cayriin (asbestos, Rusheyn kartaa, iwm). dabiiciga ah ee dhagaxyada metamorphic badanaa yaalla meel u dhow kayd ah macdanta, oo qaali ah oo dhagaxyo qaali ah semi- (guduud, sumurud, Jade, Garnet, iwm).
