Silicate minerals Silicate minerals General qauvIb silicate ntxhia yog feem ntau
an ionic compound uas nws anions muaj feem ntau ntawm silicon thiab oxygen atoms Feem ntau minerals nyob rau hauv lub ntiaj teb lub crust, txhua silicon atom yog qhov chaw ntawm ib tug zoo tagnrho tetrahedron, nws cov ces kaum yog plaub oxygen atoms covalently khi rau nws. https://en.wikipedia.org › wiki › Silicate_mineral
Silicate ntxhia - Wikipedia
yog tsim nyob ib ncig ntawm lub molecular ion hu ua silicon-oxygen tetrahedron. Ib lub tetrahedron muaj cov duab zoo li pyramid nrog plaub sab thiab plaub fab. Silicate minerals tsim pab pawg loj tshaj plaws ntawm cov zaub mov hauv ntiaj teb, suav nrog feem ntau ntawm lub ntiaj teb mantle thiab crust.
YPuas yog silica tetrahedron yog cov ntxhia?
Feem ntau ntawm cov ntxhia hauv ntiaj teb cov pob zeb, los ntawm cov pob zeb mus rau cov tub ntxhais hlau, yog cov tshuaj lom neeg ua silicates. Cov no silicate cov ntxhia yog tag nrho raws li cov tshuaj hu ua silica tetrahedron.
Yuav ua li cas cov pob zeb hauv av tsim cov qauv tetrahedron?
Cov txheej txheem yooj yim ntawm tag nrho silicate minerals yog silicon tetrahedron uas ib lub silicon atom nyob ib puag ncig thiab sib koom ua ke rau (piv txwv li, koom tes nrog) plaub lub pa oxygen, txhua qhov ntawm lub ces kaum ntawm ib txwm tetrahedron.
Yuav ua li cas cov zaub mov hauv qab no yog tsim los ntawm cov ntawv tetrahedra?
Quartz tsuas muaj silica tetrahedra. Peb lub ntsiab feldspar minerals yog poov tshuaj feldspar, (aka K-feldspar lossis K-spar) thiab ob hom plagioclase feldspar: albite (sodium nkaus xwb) thiab anorthite (calcium nkaus xwb).
Yuav ua li cas cov pob zeb hauv av tsim los ntawm ib txoj hlua ntawm silicon oxygen tetrahedra?
4. Hauv pyroxene, silica tetrahedra txuas ua ke hauv ib txoj hlua, qhov twg ib qho oxygen ion los ntawm txhua lub tetrahedron koom nrog cov tetrahedron uas nyob ib sab, yog li muaj cov pa oxygen tsawg dua hauv cov qauv.
