A mafic ntxhia lossis pob zeb yog cov pob zeb silicate lossis pob zeb tsis muaj zog uas muaj magnesium thiab hlau. Feem ntau mafic minerals yog xim dub, thiab ntau pob zeb-forming mafic minerals muaj xws li olivine, pyroxene, amphibole, thiab biotite. Cov pob zeb mafic feem ntau suav nrog bas alt, diabase thiab gabbro.
mafic thiab felsic txhais li cas?
Mafic cov zaub mov feem ntau yog dark hauv cov xim thiab muaj qhov tshwj xeeb siab (ntau dua 3.0). … Felsic minerals feem ntau yog lub teeb nyob rau hauv cov xim thiab muaj ib qho gravities tsawg dua 3.0. Feem ntau felsic minerals muaj xws li quartz, muscovite mica, thiab orthoclase feldspars.
piv txwv ntawm mafic yog dab tsi?
Mafic yog ib lo lus siv los piav txog cov zaub mov uas muaj hlau thiab magnesium thiab pob zeb uas nplua nuj nyob hauv cov zaub mov. Cov piv txwv ntawm mafic minerals muaj xws li olivine, biotite, hornblende, thiab pyroxene Qhov txawv ntawm mafic minerals yog cov zaub mov felsic, uas tsis muaj hlau thiab magnesium.
pob zeb yog mafic?
Mafic pob zeb suav nrog bas alt, nws qhov sib npaug ntawm gabbro, thiab ntau hom pob zeb tsis tshua muaj ntau dua lossis qis dua ntawm Na thiab K. Andesite thiab nws qhov sib npaug sib npaug, diorite, nrog me ntsis silica cov ntsiab lus, yog nruab nrab ntawm mafic thiab felsic.
Mafic tseem hu ua dab tsi?
Cov chav kawm ntawm pob zeb uas crystallizes los ntawm silicate minerals ntawm qhov kub thiab txias yog qee zaum hu ua "mafic" pob zeb. Nws kuj yog qee zaum hu ua bas altic vim cov chav kawm suav nrog bas alt thiab gabbro.
