Dab tsi ntawm pawg pob zeb hauv qab no, yog tias muaj cov silicon: carbonates, halides, lossis sulfides? tsis muaj. Carbonates, halides thiab sulfides yog tag nrho cov nonsilicates.
YPuas carbonates muaj silicon?
Silicates muaj silicon atom ncig los ntawm plaub lub atoms oxygen. Quartz (silicon dioxide, SiO2) yog ib hom silicate. Carbonates muaj cov pa roj carbon atom ncig los ntawm peb cov pa oxygen. Calcite (calcium carbonate, CaCO3) yog ib qho carbonate uas muaj nyob hauv limestones.
Yuav ua li cas cov zaub mov muaj silicon?
Silicon yeej tsis pom nyob hauv nws lub xeev ntuj, tab sis theej ua ke nrog oxygen raws li silicate ion SiO44 - hauv cov pob zeb uas muaj silica xws li obsidian, granite, diorite, thiab sandstone Feldspar thiab quartz yog cov ntxhia silicate tseem ceeb tshaj plaws.
Yog halides minerals?
Halide minerals yog s alts. Lawv tsim thaum dej ntsev evaporates. Cov chav kawm ntxhia no suav nrog ntau dua li cov lus ntsev xwb. Halide minerals yuav muaj cov ntsiab lus fluorine, chlorine, bromine, los yog iodine.
Qhov twg ntawm ob pawg tseem ceeb ntawm cov zaub mov muaj ntau dua hauv lub ntiaj teb crust?
Qhov kwv yees li 1,000 silicate minerals ua ntau dua 90% ntawm lub ntiaj teb crust. Silicates yog nyob deb ntawm pawg pob zeb loj tshaj plaws. Feldspar thiab quartz yog ob qho tib si silicate minerals. Ob qho tib si yog cov pob zeb ua pob zeb ntau heev.
