Hauv geology, a pluton yog lub cev ntawm intrusiveigneous pob zeb (hu ua a plutonic pob zeb ) uas yog crystallized los ntawm magma maj mam txias hauv qab ntawm lub ntiaj teb. Feem ntau pob zeb hom hauv plutons Cov pob zeb no yog granite, granite, tonalite, monzonite, thiab quartzdiorite.

Ib yam li ntawd, dab tsi yog intrusive lossis plutonic igneous pob zeb?

Intrusive pob zeb , kuj hu plutonic pob zeb , igneous pob zeb tsim los ntawm magma yuam mus rau hauv cov laus pob zeb nyob rau hauv qhov tob hauv lub ntiaj teb lub crust, uas ces maj mamsolidifies hauv qab lub ntiaj teb saum npoo, txawm hais tias nws yuav tom qab raug erosion. Igneous intrusion tsim ntau yam pob zeb hom.

2 hom igneous pob zeb yog dab tsi? Igneous pob zeb yog tsim los ntawm lava los yog magma. Magma yog molten pob zeb uas yog underground thiab lava yog molten pob zeb uas erupts tawm ntawm qhov chaw. Cov ob lub ntsiab hom pob zeb igneous yog plutonic pob zeb andvolcanic pob zeb . Plutonic pob zeb yog tsim thaum magmacools thiab solidifies underground.

Hais txog qhov no, koj qhia li cas yog pob zeb yog volcanic lossis plutonic?

Plutonic pob zeb tseem coarser grained, yog ua los ntawm loj interlocking crystals whereas pob zeb volcanic yog zoo-grained. Volcanic pob zeb kuj tsim heev heev whereas lub tsim ntawm plutonic pob zeb yog qeeb dua.

Dab tsi yog qhov sib npaug plutonic ntawm andesite?

Gabbro, ua plutonic sib npaug ntawm basalt, ismafic thiab diorite, lub plutonic sib npaug ntawm andesite , isof nruab nrab muaj pes tsawg leeg.
