Cov pob zeb zoo nkauj hu ua "extrusive" thiab feem ntau tsim tawm dhau ntawm hluav taws kub tawg.
Yuav ua li cas cov pob zeb zoo li tsis muaj pob zeb tsim?
Zoo-grained igneous rocks form thaum lava txias sai sai ntawm lub ntiaj teb nto.
cov pob zeb ntxhib ntxhib pob zeb tsim nyob qhov twg?
Yog tias cov magma nyob hauv lub ntiaj teb thiab siv ntau txhiab xyoo kom txias, nws muaj sijhawm los ua cov pob zeb loj. Cov pob zeb no ua rau pob zeb ntxhib-grained igneous pob zeb hu ua plutonic, los yog intrusive, igneous pob zeb vim hais tias cov magma tau intruded mus rau hauv cracks tob hauv qab lub ntiaj teb nto
Yuav ua li cas cov pob zeb igneous yog grained?
Extrusive igneous rocks have a fine-grained or aphanitic texture, in which the grains me too see with the unided eye. Qhov zoo-grained zoo nkauj qhia tau hais tias lub cua txias sai sai tsis muaj sij hawm los loj hlob muaju. Cov pob zeb me me no tuaj yeem pom nyob rau hauv petrographic microscope [1].
pob zeb igneous dab tsi yog lawv tsim?
Igneous pob zeb tsim thaum magma (molten pob zeb) txias thiab crystallizes, txawm nyob rau ntawm lub roob hluav taws nyob rau saum npoo ntawm lub ntiaj teb los yog thaum lub pob zeb melted tseem nyob rau hauv lub crust. Tag nrho cov magma tsim nyob rau hauv av, nyob rau hauv lub qis crust los yog sab sauv mantle, vim hais tias ntawm lub kub kub nyob rau ntawd.
