Yim Cov ntsiab lus ua rau 98% ntawm lub ntiaj teb pob zeb: oxygen, silicon, txhuas, hlau, magnesium, calcium, sodium thiab potassium. Cov muaj pes tsawg leeg ntawm cov ntxhia tsim los ntawm cov txheej txheem igneous yog ncaj qha tswj los ntawm chemistry ntawm niam txiv lub cev.
Nyob rau hauv kev hwm rau qhov no, dab tsi yog qhov feem ntau pob zeb tsim pob zeb?
Cov feem ntau pob zeb - tsim cov minerals yog silicates (saib Vol. IVA: Cov ntxhia Cov chav kawm: Silicates), tab sis lawv kuj suav nrog oxides, hydroxides, sulfides, sulfates, carbonates, phosphates, thiab halides (saib Vol.
Kuj Paub, dab tsi yog 8 cov zaub mov feem ntau?
- Cov tshuaj lom neeg feem ntau nyob rau hauv cov tawv nqaij yog oxygen (46.6%), silicon (27.7), txhuas (8.1), hlau (5.0), calcium (3.6), potassium (2.8), sodium (2.6), thiab magnesium (2.1)..
- Ntau tshaj 90% ntawm lub crust yog tsim los ntawm silicate minerals.
- Plagioclase yog cov ntxhia tseem ceeb tshaj plaws hauv lub pob zeb.
Hais txog qhov no, dab tsi yog 10 feem ntau pob zeb tsim cov zaub mov?
