Peb cov lus qhia cleavage: yog lawv sib tshuam ntawm 90˚ = cubic cleavage; yog tias cov ces kaum tsis yog 90˚ = rhombohedral . Minerals nrog 4 lossis 6 cleavages tsis yog ntau. Plaub lub dav hlau cleavage tuaj yeem tsim 8-sided duab = octahedral cleavage (piv txwv li, fluorite).

Ib yam li ntawd, tej zaum koj yuav nug, dab tsi ntxhia cleaves nyob rau hauv plaub cov lus qhia?

Ob lub dav hlau cleavage hauv gypsum sib tshuam ntawm 90 °, qhov thib peb tsis. Cov ntxhia nrog plaub los yog rau cleavage cov lus qhia tsis muaj ntau. Plaub cleavage dav hlau tuaj yeem hla los ua ib daim duab yim sab hu ua octahedron (Daim duab 12). Fluorite yog feem ntau ntxhia nrog octahedral cleavage.

Yuav ua li cas minerals tsim cleavage? Hauv ntxhia cov ntsiab lus, cleavage piav qhia txog yuav ua li cas lub pob zeb tawg thaum muaj kev ntxhov siab ntawm ib lub dav hlau tshwj xeeb. Yog hais tias ib feem ntawm cov siv lead ua tawg vim muaj kev ntxhov siab thiab cov khoom tawg tau khaws lub dav hlau du lossis siv lead ua zoo li qub, lub ntxhia muaj cleavage.

Khaws qhov no hauv kev xav, dab tsi yog qhov cleavage ntawm cov ntxhia?

Cleavage yog qhov nyiam ntawm a ntxhia txhawm rau ua kom cov dav hlau du sib npaug mus rau thaj chaw ntawm kev sib txuas tsis muaj zog. Fracture yog qhov nyiam ntawm a ntxhia kom tawg raws nkhaus nto yam tsis muaj cov duab meej. Cov no cov ntxhia tsis muaj cov dav hlau tsis muaj zog thiab tawg irregularly.

Dab tsi mineral muaj hardness ntawm 7?
