Basalt yog dab tsi

Basalt yog xim dub, nplua-grained igneous pob zeb uas feem ntau muaj xws li plagioclase, pyroxene, thiab olivine minerals. Nws yog ib qho ntawm ntau hom pob zeb volcanic thiab yog tsim los ntawm qhov txias txias ntawm basaltic lava ntawm lossis ze ntawm lub ntiaj teb saum npoo.

Xim: Basalt feem ntau tshwm hauv cov xim dub, tsaus grey, lossis ntsuab tsaus. Qee lub sij hawm nws tuaj yeem muaj qhov sib xyaw ntawm cov ntxhia pob zeb uas ua rau nws zoo li speckled.

Kev ntxhib los mos: Basalt muaj qhov zoo-grained kev ntxhib los mos vim qhov txias txias ntawm lava, uas tiv thaiv kev tsim cov muaju loj. Txawm li cas los xij, nws tseem tuaj yeem muaj vesicular lossis ntxeem tau zoo nkauj yog tias cov npuas roj tau raug daig thaum lub zog khov.

Ceev thiab Hardness: Basalt yog tuab thiab tawv, ua rau nws cov khoom siv ruaj khov. Nws muaj Mohs hardness ntawm ib ncig ntawm 6-7.

Kev sib xyaw: Basalt yog nplua nuj nyob rau hauv hlau thiab magnesium thiab tsawg nyob rau hauv silica, nws txawv ntawm lwm yam igneous pob zeb zoo li granite.

Tsim: Nws tsim los ntawm kev ua kom txias thiab khov ntawm lava ntws, feem ntau nyob rau hauv nruab nrab dej hiav txwv ridges, volcanic Islands tuaj, thiab cov cheeb tsam volcanic continental.

Kev tsim kho: Basalt feem ntau yog siv los ua cov khoom siv hauv tsev vim nws lub zog thiab kav ntev. Nws yog siv nyob rau hauv kev tsim kho ntawm txoj kev, choj, vaj tse, thiab monuments.

Aggregates: Crushed basalt yog siv los ua ib qho aggregate hauv pob zeb, asphalt, thiab txoj kev hauv paus cov ntaub ntawv. Nws hardness thiab ntom ua rau nws zoo tagnrho rau cov ntawv thov no.

Railway Ballast: Lub durability thiab hardness ntawm basalt ua rau nws haum rau siv raws li railway ballast, uas txhawb thiab stabilizes railway lem.

Pob zeb zoo nkauj: Polished basalt yog siv rau kev kho kom zoo nkauj hauv kev tsim kho kom zoo nkauj, vaj ornaments, thiab architectural ntsiab zoo li kab thiab cladding.

Pob zeb Wool: Basalt yog siv los tsim pob zeb wool (tseem hu ua pob zeb wool), cov khoom siv rwb thaiv tsev. Lub pob zeb yog melted thiab spun rau hauv fibers los tsim ib tug zoo heev insulating khoom.

Paving pob zeb: Basalt yog siv rau paving pob zeb vim nws txoj kev zoo nkauj thiab kev ua haujlwm ntev, ua rau nws yog qhov kev xaiv nrov rau txoj hauv kev, txoj kev tsheb, thiab patios.

Basalt Fiber ntau: Basalt fibers, ua los ntawm cov nplua basalt strands, yog siv rau hauv cov ntaub ntawv sib xyaw rau kev tsim kho, tsheb, thiab kev lag luam aerospace. Lawv muaj nuj nqis rau lawv lub zog, thermal kuj, thiab tshuaj stability.

Art thiab Sculpture: Vim nws ua haujlwm tau zoo thiab zoo nkauj zoo nkauj, basalt kuj tseem siv los ntawm cov kws kos duab thiab cov sculptors los tsim cov duab, carvings, thiab lwm yam artworks.

Oceanic Crust: Basalt yog thawj pob zeb uas pom nyob rau hauv dej hiav txwv crust, tsim nyob rau hauv nruab nrab ntawm dej hiav txwv ridges uas tectonic daim hlau diverging.

Volcanic Kev Ua Si: Basaltic lava ntws yog muaj nyob rau hauv thaj chaw volcanic thoob ntiaj teb, xws li Hawaiian Islands thiab Deccan Traps hauv Is Nrias teb.

Phaj Tectonics: Basalt plays lub luag haujlwm tseem ceeb hauv kev kawm ntawm phaj tectonics, vim nws tsim thiab kev faib tawm muab kev nkag siab rau cov txheej txheem uas tshwm sim ntawm divergent thiab convergent phaj ciam teb.

Lub pob zeb basalt yog ntau yam thiab dav siv pob zeb nrog qhov tseem ceeb hauv kev tsim kho thiab kev tshawb fawb geological.
