Nrog rau kev tsim ntawm biotite, lub discontinuous series officially xaus, tab sis muaj peev xwm ua tau ntau dua rau nws yog tias magma tsis tau txias tag thiab nyob ntawm cov yam ntxwv ntawm cov magma. Piv txwv li, cov kua dej kub magma tuaj yeem ua kom txias thiab daim ntawv poov tshuaj feldspar, muscovite los yog quartz.

Raws li, Bowen cov tshuaj tiv thaiv series piav txog dab tsi?

Bowen cov tshuaj tiv thaiv series yog ib txoj hauv kev los txheeb xyuas cov igneous silicate minerals los ntawm qhov kub ntawm qhov uas lawv crystallize. Minerals nyob rau sab saum toj muaj qhov kub siab crystallization, uas txhais tau hais tias lawv yuav yog thawj cov zaub mov kom crystallize los ntawm magma uas txias.

Ib tug kuj yuav nug, uas ob lub pob zeb crystallize tawm ntawm lub yaj ua ntej raws li Bowen cov tshuaj tiv thaiv series? Cov kab ke uas cov minerals 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, olivine feem ntau crystallizes ua ntej, ntawm 1200 ° thiab 1300 ° C.

Ua raws li qhov no, vim li cas Bowen cov tshuaj tiv thaiv tseem ceeb?

Bowen cov tshuaj tiv thaiv series muaj peev xwm piav qhia tias yog vim li cas qee hom minerals yuav pom ua ke thaum lwm tus yuav luag tsis cuam tshuam nrog ib leeg. Raws li Bowen tus ua hauj lwm, ib tug yuav infer los ntawm cov minerals tam sim no nyob rau hauv lub pob zeb tus txheeb ze tej yam kev mob nyob rau hauv uas cov ntaub ntawv tau tsim.

Dab tsi yog qhov kev txiav txim ntawm cov ntxhia crystallization ua raws li cov ceg tsis tu ncua ntawm Bowen cov tshuaj tiv thaiv series?

Lub nruam ceg piav qhia txog kev hloov pauv ntawm plagioclase feldspars thaum lawv hloov zuj zus los ntawm kev nplua nuj calcium kom ntau sodium nplua nuj. Cov ceg tsis tu ncua piav qhia txog kev tsim ntawm mafic cov ntxhia olivine, pyroxene, amphibole, thiab biotite mica.
