Pob zeb basalt yog hom twg?
Basalt yog pob zeb igneous
Basalt yog ib lub pob zeb ntuj uas muaj ntau heev uas yog ib hom pob zeb igneous. Cov pob zeb igneous yog cov pob zeb uas tsim los ntawm kev txias thiab khov ntawm cov magma molten ntawm qhov kub siab. Basalt yog siv dav hauv kev tsim kho, kev, thiab vaj vim nws cov khoom tshwj xeeb, xws li kev nyuaj siab, cov noob zoo, thiab cov qauv compact.
Cov khoom thiab cov qauv ntawm basalt
Basalt muaj cov khoom zoo heev nrog cov pob zeb zoo thiab cov khoom siv crystallization zoo, ua rau muaj cov qauv tawv thiab sib xws. Lub pob zeb no yog tawv, hnav-resistant, acid thiab alkali-resistant, thiab muaj kev hloov pauv zoo rau txhua yam ib puag ncig hnyav. Tib lub sijhawm, lub Tshuaj lom neeg Cov khoom sib xyaw ua ke ntawm basalt yog dominated los ntawm silicates thiab muaj ntau yam minerals, muab nws qhov ceev ceev thiab lub zog compressive zoo heev.
Cov cheeb tsam siv ntawm basalt
Nyob rau hauv thaj teb ntawm Kev Tsim Kho, basalt feem ntau siv rau kev kho kom zoo nkauj sab hauv tsev thiab sab nraum zoov, xws li pem teb thiab phab ntsa. Nws cov xim ruaj khov thiab kev ua kom ruaj khov zoo ua raubasalt Pob zeb qhia txog kev zoo nkauj tshwj xeeb hauv kev tsim kho. Hauv kev tsim kho txoj kev, basalt kuj tseem siv dav hauv kev ntug kev, kev paving txoj kev, thiab lwm yam, nws cov yam ntxwv tawv thiab ruaj khov tuaj yeem tiv taus kev tsoo ntawm cov tsheb. Tsis tas li ntawd, hauv kev tsim kho av, basalt kuj tseem siv los ua rockery, sculpture, thiab lwm yam chaw ua vaj.
Kev khawb thiab ua cov basalt
Basalt Feem ntau yog khawb rau hauv qhov chaw qhib uas cov xwm txheej geological haum. Thaum lub sijhawm ua tiav, basalt yog ua rau ntau qhov ntau thiab tsawg ntawm cov pob zeb tsim kho los ntawm kev txiav, sib tsoo, polishing, thiab lwm yam txheej txheem. Vim nws qhov nyuaj nruab nrab thiab yooj yim ua tiav, nws ua rau kev khawb thiab ua tiav basalt yooj yim thiab pheej yig.
Basalt yog ib lub pob zeb igneous uas muaj zog heev, tsis yooj yim rau kev sib txhuam, tsis yooj yim rau kua qaub thiab alkali, thiab lwm yam. Nws siv dav hauv kev tsim kho, kev, vaj, thiab lwm yam. Nws cov yam ntxwv tshwj xeeb thiab ntau yam kev siv ua rau basalt yog ib lub pob zeb ntuj tseem ceeb.
