Andesite feem ntau yog porphyritic, muaj cov muaju loj (phenocrysts) ntawm plagioclase tsim ua ntej extrusion uas coj cov magma rau saum npoo, embedded nyob rau hauv ib tug finer-grained matrix.
Porphyritic andesite ua li cas?
Porphyritic kev ntxhib los mos - andesite: Qhov no yog pob zeb extrusive igneous. Lub magma los ntawm qhov uas nws tsim txias maj mam rau ib pliag tob hauv qab ntawm qhov chaw (ua cov pob zeb loj), tom qab ntawd ua tiav txias sai heev thaum nws tawm ntawm qhov chaw, tsim cov nplua-grained. avmass.
Puas yog andesite a porphyritic?
Andesite feem ntau txhais tau tias fine-grained, feem ntau yog pob zeb porphyritic; Nyob rau hauv muaj pes tsawg leeg no sib raug zoo mus rau intrusive igneous pob zeb diorite thiab tseem ceeb ntawm andesine (ib plagioclase feldspar) thiab ib los yog ntau tshaj ferromagnesian minerals, xws li pyroxene los yog biotite.
Dab tsi yog cov yam ntxwv ntawm cov pob zeb andesitic?
Andesite yog ib tsaus, nplua-grained, xim av lossis greyish nruab nrab volcanic pob zebuas yog ib qho pom muaj nyob hauv lava. Cov ntxhia muaj pes tsawg leeg ntawm andesite suav nrog biotite, pyroxene, lossis amphibole.
Porphyritic andesite composition yog dab tsi?
Tsaus Ntsuab. Mineral Composition. YSodium – Calcium Plagioclase, Pyroxene, Hornblende. Hornblende Phenocrysts nyob rau hauv ib qho aphanitic (fine-grained) groundmass.
