Feem ntau, txhua yam igneous intrusion -ib pob zeb loj uas tsim thaum magma txias hauv lub ntiaj teb sab hauv - tej zaum yuav hu ua pluton. Dikes, sills, laccoliths, thiab volcanic caj dab qee zaum hu ua plutons. Txawm li cas los xij, qee cov kws tshawb fawb pom tsuas yog tus loj tshaj plaws , tuab kev cuam tshuam ua plutons.
Xav txog qhov no, dab tsi yog igneous intrusion?
Ib igneous intrusion (tseem hu ua laccolith los yog plutonic tsim) yog ib qho kev tsim nyob rau hauv uas magma (molten pob zeb) yog daig hauv qab ntawm lub ntiaj teb thiab thawb lub pob zeb nyob saum nws mus rau hauv ib lub dome. Nws muaj lub hauv paus tiaj tus thiab convex saum npoo.
Ib tug kuj nug, 6 hom kev nkag mus yog dab tsi? Ib qho kev nkag mus yog lub cev ntawm igneous (tsim nyob rau hauv kub kub) pob zeb uas tau crystallized los ntawm molten magma.
Dhau li ntawm saum toj no, dab tsi yog qhov sib txawv ntawm igneous intrusion?
Peb hom kev nkag mus yog sills, dykes, thiab batholiths (saib duab hauv qab)
- Sills: daim ntawv thaum magma intrudes ntawm cov pob zeb txheej, tsim ib kab rov tav los yog maj mam-dipping daim ntawv ntawm igneous pob zeb.
- Dykes: daim ntawv li magma thawb mus rau saum npoo los ntawm cov kab nrib pleb hauv pob zeb.
- Batholiths:
Dab tsi yog 3 hom igneous lub cev?
Feem ntau hom pob zeb igneous yog:
- andesite.
- basalt.
- dacite.
- dolerite (tseem hu ua diabase)
- gabbro ua.
- diorite.
- peridotite.
- neej.
