Samples yeMetamorphic Rock 24 Mhando

24 Mhando / bhokisi, saizi bhokisi 39.5x23x4.5cm

Maererano negenesis yavo, matombo anonyanya kuve akapatsanurwa muzvikamu zvitatu: igneous rocks (magmatic rocks), sedimentary matombo uye metamorphic matombo. Muchikamu chose, matombo ane igneous anoverengera 95%, sedimentary rocks account isingasviki 5%, uye metamorphic matombo ari mashoma. Zvisinei, mumatanho akasiyana, miganho yekuparadzira yemhando nhatu dzematombo inosiyana zvakanyanya. 75% yematombo ari pamusoro ndeye sedimentary matombo, uye chete 25% yematombo ane igneous. Iyo yakadzika chinhambwe kubva pamusoro, inowedzera igneous uye metamorphic matombo. Iyo yakadzika goko uye yekumusoro jasi inowanzo kuve inoumbwa negneous matombo uye metamorphic matombo. Igneous matombo akaenzana ne64.7% yeiyo yakazara crustal vhoriyamu, metamorphic matombo aiita 27.4%, uye sedimentary matombo aiita 7.9%. Pakati pavo, basalt uye gabbro inokwana 65,7% yematombo ese anopisa, uye girenayiti uye mamwe matombo akajeka-mavara angangoita 34%.
Musiyano uripo pakati pemhando idzi nhatu dzematombo hauna kukwana. Sezvinochinja zvicherwa, zvivakwa zvavo zvichachinjawo. Sezvo nguva nenharaunda zvinoshanduka, zvinoshanduka kuita matombo ehumwe hunhu
