Olivine ua tsis tshwm sim nrog cov ntxhia quartz . Quartz tau tsuas yog tsim los ntawm magmas uas muaj txheeb ze nplua nuj nyob rau hauv silica, thaum lub olivine Cov zaub mov tsuas yog tsim los ntawm magmas uas yog lean hauv silica, yog li quartz thiab olivine yog incompatible minerals.

Kuj tseem yuav paub yog, vim li cas olivine thiab quartz tsis zoo li yuav pom ua ke hauv tib lub pob zeb tsis zoo?

Nws yog vim li no quartz tsis yog pom nrog olivine , corundum, sodalite lossis lazurite. Cov zaub mov no tsuas yog tsis muaj tshuaj lom neeg ruaj khov ua ke . Tsis muaj cov ntxhia hauv magma - tsuas yog xoob atoms darting ncig. Raws li cov magma txias, cov atoms pib sib txuas ua ke tsim cov minerals.

Ib tug kuj yuav nug, qhov twg yog olivine nyob rau hauv lub ntiaj teb? Qhov chaw nyob Olivine feem ntau yog pom nyob rau hauv cov xim tsaus nti igneous pob zeb pom nyob rau hauv qhov chaw ntawm lub Lub ntiaj teb . Cov pob zeb no feem ntau nyob nyob rau hauv daim hlau tectonic thiab divergent phaj ciam teb. Olivine muaj lub siab crystallization kub uas ua rau nws yog ib qho ntawm thawj mineralize mus crystallize los ntawm lub Lub ntiaj teb kub.

Yog li ntawd, hom pob zeb twg yog olivine?

igneous pob zeb

olivine muaj pes tsawg cleavage?

Lub cev muaj zog. Qhov tshwj xeeb gravity thiab hardness ntawm lub cov olivines muaj npe nyob rau hauv Table. Muaj tsawg kawg yog ob qhov cleavages-piv txwv li, txoj kev nyiam sib cais raws cov kev qhia crystallographic nyiam (perpendicular mus rau a thiab b axes nyob rau hauv cov ntaub ntawv no) - ob qho tib si yog zoo-tsim nyob rau hauv cov hlau nplua nuj ntau yam.
