Basalt . Basalt yog a Feem ntau cov pob zeb uas muaj xim daj-xim av uas muaj calcic plagioclase (feem ntau yog labradorite), clinopyroxene (augite) thiab hlau ore (titaniferous magnetite). Basalt kuj tseem muaj olivine, quartz, hornblende, nepheline, orthopyroxene, thiab lwm yam. Basalt yog a volcanic sib npaug ntawm gabbro.

Hais txog qhov no, dab tsi cov zaub mov muaj nyob hauv Basalt?

Lub mineralogy ntawm basalt yog yus muaj los ntawm ib tug preponderance ntawm calcic plagioclase feldspar thiab pyroxene . Olivine kuj tseem tuaj yeem yog qhov tseem ceeb. Accessory minerals tam sim no nyob rau hauv cov me me muaj xws li hlau oxides thiab hlau- titanium oxides, xws li magnetite, ulvöspinel, thiab ilmenite.

Ib yam li ntawd, puas yog Basalt ntawm lub rooj zaum? Strontium nyob rau hauv igneous pob zeb. Strontium (cim Sr, atomic naj npawb 38) occupies tib pab pawg nyob rau hauv lub Lub Sijhawm Sijhawm raws li qhov loj keeb Ca. Hauv feem ntau basalts , Sr cov ntsiab lus feem ntau yog li ntawm 100 txog 1000 ppm.
