minerals uas crystallize ntawm qhov kub qis tshaj (quartz, muscovite, alkali feldspar) yog nplua nuj nyob rau hauv Si thiab Al; pob zeb uas muaj cov minerals no yog felsic nyob rau hauv muaj pes tsawg leeg (granite, rhyolite).
Yuav ua li cas ntawm cov pob zeb tsis pom kev hauv qab no muaj cov zaub mov uas crystallize ntawm qhov kub thiab txias?
Granite yog ib lub pob zeb ntxhib ntxhib ntxhib uas muaj ntau alkali feldspar. Granites kuj muaj quartz. Qhov no yog qhov sib dhos uas tsis muaj qhov kub thiab txias.
Yuav ua li cas cov zaub mov crystallize kawg los ntawm txias magma?
Ntawm cov khoom siv silicate ntau, olivine feem ntau crystallizes ua ntej, ntawm 1200 ° thiab 1300 ° C. Raws li qhov kub thiab txias poob, thiab xav tias qee cov silica tseem nyob hauv magma, cov olivine muaju yuav hnov mob (sib txuas) nrog qee cov silica hauv magma los ua pyroxene.
Yuav ua li cas ntxhia yog thawj zaug kom crystallize los ntawm magma chamber thiab qhov kub thiab txias?
Cov kab ke uas cov ntxhia crystallize los ntawm magma yog hu ua Bowen cov tshuaj tiv thaiv series (Daim duab 3.10 thiab leej twg yog Bowen). Ntawm cov khoom siv silicate ntau, olivine feem ntau crystallizes ua ntej, ntawm 1200 ° thiab 1300 ° C.
Qhov kub npaum li cas calcium nplua nuj anorthite crystallize ntawm?
Piv txwv li, tus cwj pwm crystallization ntawm anorthite los ntawm cov yaj ntawm tib cov muaj pes tsawg leeg tau txiav txim siab tshaj qhov kub thiab txias nruab nrab ntawm 1, 173thiab 1, 273 K thiab nruab nrab ntawm 1, 523 thiab 1, 773 K (Klein thiab Uhlmann, 1974).
