Qhov txawv ntawm Marble thiab Granite

1. Marble feem ntau yog tsim nyob rau hauv Dali, Yunnan, Suav teb. Nws yog ib hom pob zeb metamorphic. Nws yog ib hom pob zeb tsim los ntawm kev ua lub luag haujlwm nrog cov zaub mov ntawm qhov kub thiab txias. Nws yuav hloov txhua yam Arts, science thiab xim, thiab txawm recrystallize. Ntuj marble yog tsim los ntawm calcite, limestone, dolomite, serpentine, thiab lwm yam. Feem ntau hais lus, tus qauv zoo nkaus li pom tseeb thiab muaj ntau cov ntxhia hais. Ntxiv mus, marble muaj zog compression kuj, yooj yim tu thiab tsis tshua muaj dej nqus.

2. Marble yog yooj yim rau corroded thiab eroded, yog li lub pob zeb nto yog ib qho yooj yim kom poob luster thiab tsis tshua muaj hluav taws xob. Yog li ntawd, nws yog feem ntau siv rau kev kho kom zoo nkauj sab hauv tsev, thiab ob peb nrog kev ruaj khov zoo tuaj yeem siv rau kev kho kom zoo nkauj sab nraum zoov. Thiab vim hais tias kev kos duab thiab kev tshawb fawb yog qhov zoo heev, lawv kuj feem ntau siv rau kev kos duab. Ntxiv mus, granite muaj siab hardness, corrosion kuj, corrosion kuj, lub neej ntev kev pab cuam, tsis yooj yim rau khawb ntawm qhov chaw, cov xim yuav khaws cia rau lub sij hawm ntev, thiab radioactivity kuj siab, yog li nws yog feem ntau siv sab nraum zoov los yog nyob rau hauv ib co. cov tsev.

3. Peb yuav tsum paub tias granite belongs rau igneous pob zeb, uas yog tsim tsis muaj magma ejecting thiab txias thiab solidification underground. Nws yog soaked los ntawm ntau yam mineral gases thiab kua los tsim ntau yam xim, tab sis nws yog feem ntau tsaus. Ntuj granite yog pob zeb nyuaj. Cov khoom siv yog tawv heev thiab ruaj khov. Raws li cov nplej loj, nws tuaj yeem muab faib ua pegmatite, coarse grain, grain, thiab lwm yam Granite yog ib qho nyuaj heev, tsis yooj yim rau huab cua thiab corroded, zoo nkauj heev.
