Gabbro yog ib coarse-grained, dub-xim, intrusive igneous pob zebNws feem ntau yog xim dub lossis tsaus ntsuab xim thiab muaj feem ntau ntawm cov zaub mov plagioclase thiab augite. Nws yog pob zeb ntau tshaj plaws nyob rau hauv qhov tob dej hiav txwv crust. Gabbro muaj ntau yam kev siv hauv kev tsim kho kev lag luam.
Vim li cas gabbro yog pob zeb thiab tsis yog pob zeb?
Gabbro yog pob zeb thiab tsis yog ntxhia vim nws yog tsim los ntawm ntau cov minerals thiab crystals uas sib koom ua ke thiab sib zog ua ib qho…
Puas yog gabbro yog pob zeb lossis pob zeb?
Gabbro yog mafic intrusive coarse-grained pob zebnrog allotriomorphic kev ntxhib los mos. Gabbros muaj tsawg silicon (tsis muaj Quartz lossis Alkali feldspar) thiab qhov tseem ceeb ntawm cov zaub mov ferromagnesian thiab Plagioclase feldspar nplua nuj hauv calcium. Tus nqi ntawm ferromagnesian minerals sib npaug los yog tshaj ntawm Plagioclase.
Yog gabbro yog pob zeb?
Gabbro, ib qho ntawm ntau pob zeb nruab nrab lossis ntxhib-graineduas muaj feem ntau ntawm plagioclase feldspar thiab pyroxene. Qhov tseem ceeb, gabbro yog qhov cuam tshuam (plutonic) sib npaug ntawm bas alt, tab sis thaum bas alt feem ntau zoo sib xws hauv mineralogy thiab muaj pes tsawg leeg, gabbros yog qhov sib txawv heev.
Yuav ua li cas pob zeb tsis pom kev yog gabbro?
Gabbro yog silica-poor intrusive igneous (plutonic) pob zeb tshuaj sib npaug rau bas alt. Nws yog ib txwm ntxhib-grained, tsaus thiab feem ntau muaj feldspar, augite thiab qee zaum olivine.
