Andesitic magma yog formed los ntawm ntub ib nrab melting ntawm lub mantle. Lub mantle nyob rau hauv dej hiav txwv muaj kev sib cuag nrog dej. … Bas altic magma uas muaj cov ntsiab lus dej siab yog qhov tshwm sim. Yog hais tias hom bas altic magma melts nrog continental crust uas muaj ib tug siab ceev ntawm dioxide silicon, andesitic magma yuav tsim.

andesite magma daim ntawv nyob qhov twg?

Granitic, lossis rhyolitic, magmas thiab andesitic magmas yog tsim los ntawm convergent phaj ciam teb qhov twg dej hiav txwv lithosphere (txheej txheej ntawm lub ntiaj teb tsim los ntawm crust thiab sab sauv mantle) yog subducted kom nws cov ntug nyob hauv qab ntawm ntug ntawm daim av av lossis lwm daim ntawv dej hiav txwv.

YYog andesitic magma intermediate?

Andesitic magma -- SiO₂ 55-65 wt%, intermediate. in Fe, Mg, Ca, Na, K.

Yog andesitic magma tuab?

ANDESITIC LAVA

Cov viscous lavas muaj qhov sib piv siab (thickness / cheeb tsam), feem ntau > 1/100, thiab qee qhov tuab txaus los tsim ua lava domes.

Tus yam ntxwv ntawm andesitic magma yog dab tsi?

Andesitic magma muaj nruab nrab ntawm cov zaub mov no, nrog rau qhov kub ntawm li 800o ^{C txog 1000} o^{C (1472}o^{F to 1832}o^{F). Rhyolitic magma muaj ntau hauv potassium thiab sodium, tiam sis tsis muaj hlau, magnesium, thiab calcium. Nws tshwm sim hauv qhov kub thiab txias li ntawm 650} o ^{C txog 800}o^{C (1202}o^{F mus1472}o^F)..
