Cov khoom uas pab geologists txheeb xyuas a ntxhia Nyob rau hauv ib lub pob zeb yog: xim, hardness, luster, crystal forms, ceev, thiab cleavage. Crystal form, cleavage, thiab hardness yog txiav txim siab feem ntau los ntawm cov qauv siv lead ua ntawm qib atomic. Xim thiab ntom yog txiav txim siab los ntawm cov tshuaj muaj pes tsawg leeg.

Ib yam li ntawd, nws yog nug, dab tsi yog tshuaj muaj pes tsawg leeg ntawm cov zaub mov?

Cov muaj pes tsawg leeg ntawm a ntxhia tuaj yeem hais ua ib CHEMICAL FORMULA , uas yooj yim muab cov proportions ntawm cov ntsiab lus sib txawv thiab pab pawg ntawm cov ntsiab lus hauv ntxhia . Cov kev xav tom kawg (pab pawg ntawm cov ntsiab lus) los ua si rau cov cov ntxhia uas muaj kev txwv ntau ntawm muaj pes tsawg leeg.

Tsis tas li, vim li cas nws tseem ceeb kom paub lub cev thiab tshuaj lom neeg ntawm cov ntxhia? Tshuaj muaj pes tsawg leeg thiab siv lead ua qauv txiav txim ib mineral cov khoom , nrog rau qhov ntom ntom, zoo li, hardness, thiab xim. Vim txhua tus ntxhia daim ntawv nyob rau hauv tej yam kev mob, tshuaj xyuas cov ntxhia pab cov kws tshawb fawb nkag siab keeb kwm ntawm lub ntiaj teb thiab lwm cov ntiaj chaw nyob rau hauv peb lub hnub ci system.

Ib yam li ntawd, dab tsi yog cov yam ntxwv ntawm cov zaub mov?

Cov yam ntxwv ntawm lub cev hauv qab no tuaj yeem siv tau yooj yim los txheeb xyuas cov ntxhia:

  • Xim.
  • Streak.
  • Hardness.
  • Cleavage los yog tawg.
  • Crystalline qauv.
  • Diaphaneity los yog Qhov Muaj Peev Xwm Pom Zoo.
  • Tenacity.
  • Magnetism.

Dab tsi yog cov pob zeb sib sau ua cov ntxhia siv lawv cov khoom siv tshuaj?

Cov tshuaj muaj zog ntawm cov ntxhia nyob ntawm lawv cov tshuaj formula thiab crystal structure. Solubility thiab melting point yog tshuaj muaj zog feem ntau siv los piav txog a ntxhia . Feem ntau pob zeb - tsim cov minerals yog quartz, feldspar, mica, pyroxene, amphibole, thiab olivine.
