Basalt yog nplua-grained, tsaus ntuj - xim extrusive igneous pob zeb tsim los ntawm plagioclase thiab pyroxene. Cov qauv qhia yog li ob nti (tsib centimeters) hla. Diorite yog coarse-grained, intrusive igneous pob zeb uas muaj kev sib xyaw ntawm feldspar, pyroxene, hornblende, thiab qee zaum quartz.
Ntawm no, lub pob zeb uas tsis muaj zog yog cov xim tsaus nti txias sai sai?
Basalt
