Marble yog lub pob zeb ntuj tsim los ntawm limestone. Nws muaj chemical reactivity tsawg heev. Nws tuaj yeem yaj hauv dej los tsim calcium oxide thiab gaseous carbon dioxide. Vim hais tias ntawm cov tshuaj tsis tshua muaj tshuaj reactivity, nws yog incompatible nrog acids. Txawm li cas los xij, marble tsis hnov mob nrog concentrated acidic ntsev thiab fluorine. Yog li ntawd, koj yuav tsum tau ceev faj heev thaum siv marble.
Ntau cov marbles muaj ntau yam khoom siv ntxiv. Cov zaub mov no pab txhawb cov xim ntawm pob zeb. Qee qhov ntawm cov zaub mov no tuaj yeem ncav cuag 15 feem pua ntawm cov pob zeb marble. Piv txwv li, qee cov marbles muaj cov nplej me me ntawm quartz thiab nplai ntawm daj ntseg daj mica. Qee cov marbles kuj muaj cov hlau oxides thiab cov pob zeb me me ntawm pyrite.
Yog tias koj xav paub seb marble puas muaj tshuaj, koj tuaj yeem sim ua qhov kev sim yooj yim los kuaj koj tus kheej. Ua ntej, sib tov crushed qe nrog 70% acetic acid tov thiab 30 mL dej. Tom ntej no, ntxiv 100 mL ntawm ethyl cawv rau qhov sib tov. Cov tshuaj yuav tsum tsim ib gel. Thaum cov tshuaj no tov nrog dej, koj tuaj yeem sim ua kom sov lub marble nrog lub tshuab cua tshuab thiab pom tias nws ci. Nco ntsoov siv hnab looj tes tiv thaiv thiab daim npog ntsej muag thaum tuav cov tshuaj no.
Marble muaj calcium carbonate, ib tug ntxhia pob zeb uas muaj peev xwm ntawm neutralizing ntau acids. Qhov tseeb, marble yog zoo heev ntawm neutralizing acid uas nws yog feem ntau siv los neutralize acid nyob rau hauv dej ntws thiab pas dej. Vim nws muaj peev xwm acid-neutralization, marble feem ntau siv hauv kev lag luam tshuaj. Cov tshuaj no yog siv nyob rau hauv ntau yam khoom siv hauv tsev, nrog rau cov hmoov ntxuav. Ntxiv nrog rau kev ua cov kua qaub ntuj tsis zoo, marble yog qhov tseem ceeb rau cov duab puab thiab lwm yam dej num.
Marbles muaj nyob rau hauv cov khaubncaws sab nraud povtseg ntawm lub ntiaj teb crust, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam ntawm igneous intrusion thiab heev folding. Nyob rau hauv cov cheeb tsam metamorphic, limestone nplua nuj nyob rau hauv fossils hloov mus rau qhov tseeb marble. Qee qhov xwm txheej, marble khaws cov qauv organic, xws li limonite, hematite, thiab pyrite.
