Qhov sib txawv tseem ceeb ntawm thawj thiab theem nrab cov zaub mov yog tias cov pob zeb tseem ceeb yog tsim los ntawm cov pob zeb uas tsis muaj zog, qhov thib ob cov zaub mov yog tsim los ntawm huab cua ntawm cov pob zeb thawj.
A ntxhia yog ib txwm tshwm sim, inorganic khoom uas muaj cov qauv tshuaj zoo. Nws muaj cov yam ntxwv tshuaj muaj pes tsawg leeg thiab lub cev muaj zog. Raws li cov ntsiab lus no, ib txwm tshwm sim txhais tau hais tias ib qho ntxhia tsis yog tib neeg tsim ua ke. Inorganic txhais tau tias nws tsis yog ib yam khoom ntawm lub cev. Tsis tas li ntawd, nws tsis tshwm sim hauv cov kua lossis roj hauv lub xeev ntawm qhov ntsuas kub thiab siab.
Primary Minerals yog dab tsi?
Primary minerals yog cov khoom uas tsim los ntawm cov pob zeb tsis pom kev ntawm thawj crystallization. Qhov ntawd txhais tau tias; thawj cov zaub mov tsim los ntawm cov txheej txheem solidification. Cov qeb ntawm cov zaub mov tseem ceeb suav nrog cov zaub mov tseem ceeb (uas yog siv los muab cov npe faib rau pob zeb) thiab cov khoom siv ntxiv (uas tsis tshua muaj ntau). Ntxiv mus, qhov tseem ceeb ntawm cov zaub mov tseem ceeb yog silicate ntxhia.
Daim duab 01: Pom pom ntawm Cov Khoom Tseem Ceeb
Feem ntau, cov zaub mov tseem ceeb tsim los ntawm ib ntu lossis los ntawm cov pab pawg ua ntu zus raws li tau hais los ntawm cov tshuaj thiab lub cev. Qhov kev tsim no tshwm sim thaum lub sij hawm magma solidification. Accessory minerals, ib tug subtype ntawm thawj cov zaub mov, tsim los ntawm ntau cov kauj ruam ntawm crystallization. Txawm li cas los xij, kev suav nrog cov ntxhia hauv qeb ntawm cov zaub mov tseem ceeb yuav tsum tau tsim cov pob zeb thaum ntxov.
Qhov sib txawv tseem ceeb ntawm thawj thiab theem nrab cov zaub mov yog tias thawj cov ntxhia hauv cov khoom tsis raug hloov pauv vim lawv tsim ncaj qha los ntawm crystallization ntawm magma. Yog li ntawd, thawj cov zaub mov tuaj yeem pom hauv av tab sis lawv tsis tsim hauv av. Cov zaub mov tseem ceeb muaj txiaj ntsig zoo hauv kev txheeb xyuas geochemical dispersion halos, thiab qhia cov zaub mov.
Dab tsi yog Secondary Minerals?
Secondary minerals yog cov khoom uas tsim los ntawm kev hloov pauv ntawm cov zaub mov tseem ceeb. Qhov ntawd txhais tau tias; Cov ntaub ntawv ntxhia thib ob thaum thawj cov zaub mov tau txais tshuaj lom neeg thiab kev hloov pauv hauv thaj chaw xws li huab cua thiab kev hloov pauv hydrothermal.
Daim duab 02: Av nplaum yog ib qho khoom siv thib ob
Cov ntxhia hauv qib thib ob yog tsim thiab pom hauv av; e.g. gypsum thiab alunite yog lwm yam minerals. Ib daim ntawv ntawm cov ntxhia hauv nruab nrab yog av nplaum.
Dab tsi yog qhov sib txawv ntawm Cov Khoom Tseem Ceeb thiab Qib Thib Ob?
A ntxhia yog ib txwm tshwm sim, inorganic khoom uas muaj cov qauv tshuaj zoo. Muaj ob hom minerals uas yog thawj cov zaub mov thiab cov zaub mov thib ob. Qhov sib txawv tseem ceeb ntawm cov ntxhia hauv thawj thiab theem nrab yog cov pob zeb tseem ceeb tsim los ntawm cov pob zeb uas tsis muaj zog thaum cov pob zeb thib ob los ntawm cov huab cua ntawm cov pob zeb thawj. Yog li ntawd, thawj minerals tshwm sim nyob rau hauv cov av tab sis tsis tsim nyob rau hauv cov av, tab sis lwm yam minerals tshwm sim nyob rau hauv cov av thiab tsim nyob rau hauv cov av thiab. Qee qhov piv txwv ntawm cov zaub mov tseem ceeb suav nrog quartz, feldspar, muscovite, granite, thiab lwm yam thaum qee qhov piv txwv ntawm cov ntxhia hauv nruab nrab suav nrog av nplaum, gypsum thiab alunite.
Hauv qab infographic qhia txog qhov sib txawv ntawm cov ntxhia hauv thawj thiab theem nrab.
Summary – Primary vs Secondary Minerals
A ntxhia yog ib txwm tshwm sim, inorganic khoom uas muaj cov qauv tshuaj zoo. Muaj ob hom minerals uas yog thawj cov zaub mov thiab cov zaub mov thib ob. Qhov sib txawv tseem ceeb ntawm cov ntxhia hauv thawj thiab theem nrab yog cov pob zeb tseem ceeb tsim los ntawm cov pob zeb uas tsis muaj zog thaum cov pob zeb thib ob los ntawm cov huab cua ntawm cov pob zeb thawj. Yog li ntawd, thawj minerals tshwm sim nyob rau hauv cov av tab sis tsis tsim nyob rau hauv av tab sis lwm yam minerals tshwm sim nyob rau hauv cov av thiab cov ntaub ntawv nyob rau hauv cov av ib yam nkaus.
