Part 1 Kev xeem
- Qhia cov ntxhia thiab pob zeb sib nrug.
- Nkag siab ntxhia kev txheeb xyuas.
- Tshawb xyuas tus puab thiab nto nta ntawm themineral .
- Saib koj mineral ci, los yog luster.
- Ua tib zoo saib cov mineral xim.
- Ua ib qho streak xeem .
- Kuaj cov khoom hardness.
- So cov ntxhia thiab saib cas nws los sib nrug.
Ua li no, koj tuaj yeem ua dab tsi los ntsuas qhov ntxhia?
Geologists siv cov hauv qab no kuaj paub qhov txawv cov ntxhia thiab cov pob zeb lawv ua : hardness, xim, streak, luster, cleavage thiab tshuaj tiv thaiv. Ascratch xeem tsim los ntawm German mineralogist FredriechMohs nyob rau hauv 1822 yog siv rau txiav txim ntxhia tawv.
Qhov thib ob, dab tsi yog thawj qhov peb tab tom nrhiav thaum txheeb xyuas cov zaub mov? Cov tshuaj formula thiab siv lead ua lattice ntawm a ntxhia tsuas tuaj yeem txiav txim siab hauv chav kuaj, tab sis byexamineing a ntxhia thiab txiav txim siab ntau yam ntawm nws lub cev, koj tuaj yeem ua tau txheeb xyuas tus ntxhia . Ua ntej , koj yuav tsum paub txog lub cev muaj zog ntawm cov ntxhia thiab yuav paub lawv li cas.
Qhov thib ob, koj qhia li cas yog tias nws yog pob zeb lossis pob zeb?
[edit] A ntxhia yog ib txwm tshwm sim, inorganic khoom nrog ib tug meej tshuaj muaj pes tsawg leeg thiab acrystalline qauv tsim los ntawm geological txheej txheem. A pob zeb yog kev sib sau ua ke ntawm ib lossis ntau dua cov ntxhia hos a pob zeb kuj tseem muaj cov organic seem thiabmineraloids.
Koj tuaj yeem txiav txim siab li cas tias cov khoom tsis paub yog cov ntxhia?
Piav: Yuav kom txiav txim seb ib qho khoom tsis paub yog cov ntxhia kuaj rau txiav txim qee yam khoom yuav tsum tau ua. Mineral cov cov khoom yog qhov tseem ceeb los tsim kom muaj nws tus kheej vim tias cov khoom yog txiav txim siab los ntawm cov tshuaj muaj pes tsawg leeg thiab cov qauv siv lead ua, los yog txoj kev uas cov atoms tau npaj.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm?
Koj tuaj yeem ua li cas yog tias koj tsis paub tias txheej twg yog nyob rau hauv cov txheej txheem rho tawm? Tso dej me me rau hauv lub caj dab ntawm qhov sib cais funnel. Ua tib zoo saib nws: yog tias nws tseem nyob hauv txheej txheej sab saud, txheej txheej ntawd yog txheej dej
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Dab tsi yog cov pob zeb niam txiv ntawm cov pob zeb metamorphic?
Metamorphic pob zeb Metamorphic pob zeb Texture Niam txiv pob zeb Phyllite Foliated Shale Schist Foliated Shale, granite thiab volcanic pob zeb Gneiss Foliated Shale, granite thiab volcanic pob zeb Marble Nonfoliated Limestone, dolostone
