Andesite yog lub pob zeb grey rau dub volcanic nrog li ntawm 52 thiab 63 qhov hnyav feem pua silica (SiO2). … Andesite magma tseem tuaj yeem tsim cov tawg tawg muaj zog los ua cov pyroclastic ntws pyroclastic ntws Pyroclastic ntws tuaj yeem ua rau puas tsuaj thiab tuag taus vim lawv qhov kub thiab txias thiab txav mus los. Piv txwv li, thaum lub sij hawm 1902 eruption ntawm Mont Pelee nyob rau hauv Martinique (West Indies), ib tug pyroclastic ntws (tseem hu ua "nuee ardente") demolished lub ntug dej hiav txwv nroog ntawm St. Pierre, tua. ze li 30,000 tus neeg nyob. https://www.usgs.gov › how-dangerous-are-pyroclastic-flows

thiab surges thiab eruptions loj. Andesites tawg ntawm qhov kub ntawm 900 txog 1100 ° C.
hom magma yog tawg?
Explosive Eruptions
Felsic magmas erupt explosively because of hot, gas-rich magma churning in its chamber. Lub siab dhau los ua qhov zoo kawg nkaus uas cov magma nws thiaj li tawg lub foob thiab tawg, ib yam li thaum lub cork tawm ntawm lub raj mis ntawm champagne.
magma twg tawg tshaj?
Kev tawg tawg yog nyiam los ntawm cov ntsiab lus roj siab & siab viscosity magmas ( andesitic rau rhyolitic magmas). Cov npuas tawg tawg tawg ua rau cov magma ua rau cov kua ua kua uas txias thaum lawv poob saum huab cua.
magma twg tawg tsawg?
Lub roob hluav taws uas tawg tsawg kawg yog hu ua bas alt toj siab. Cov roob hluav taws no tsim cov kua dej bas altic magma nrog cov kab rov tav ntws. Daim ntawv ntawm cov roob hluav taws no yog tiaj tus kom maj mam nqes thiab lawv tuaj yeem nyob thaj tsam ntawm 100, 000 txog 1, 000, 000 square kilometers.
Lub roob hluav taws dab tsi yog tawg?
volcanoes sib xyaw yog qee lub roob hluav taws txaus ntshai tshaj plaws hauv ntiaj teb. Lawv zoo li tshwm sim raws ntug dej hiav txwv-rau- dej hiav txwv lossis dej hiav txwv-rau-sab av loj vim yog thaj tsam subduction. Lawv zoo li ua los ntawm felsic mus rau nruab nrab pob zeb thiab lub viscosity ntawm lava txhais tau hais tias eruptions zoo li tawg.

Puas yog kev tawg thiab tawg tsis tuaj yeem?
Lub voj voog tawg thiab tawg yog qhov hloov pauv ntawm kev loj hlob ntawm kev lag luam thiab poob qis. Nws yog lwm txoj hauv kev los piav qhia txog lub voj voog kev lag luam lossis kev lag luam nyiaj txiag. Raws li Tsoom Fwv Teb Chaws Reserve Bank ntawm Richmond, cov theem no yog inevitable .
Puas yog andesitic lava khov?
Andesitic lava yog ib qho piv txwv ntawm a siab viscosity lava whereas balastic lava muaj viscosity tsawg, yog li muaj dej ntau. High silica cov ntsiab lus nyob rau hauv lub andesitic lava pab ua rau lub siab viscosity thiab tsawg silica cov ntsiab lus nyob rau hauv lub bas altic lava txhais tau hais tias nws yog ib tug qis viscosity .
