Ib tug mineral uas qhia ' zoo tag nrho ' cleavage tawg yooj yim, nthuav tawm tas li, tiaj tus nto uas cuam tshuam lub teeb. Fluorite, calcite, thiab barite yog cov ntxhia nws cleavage yog zoo tag nrho . 'Qhov txawv' cleavage txhais hais tias cleavage Cov chaw muaj nyob txawm hais tias lawv yuav raug puas tsuaj los ntawm kev tawg lossis tsis zoo.

Hais txog qhov no, cleavage txhais li cas hauv geology?

Cleavage yog qhov nyiam ntawm cov pob zeb hauv av kom tawg raws cov dav hlau du uas sib npaug mus rau thaj chaw ntawm kev sib txuas tsis muaj zog. pob txha yog qhov nyiam ntawm cov pob zeb hauv av kom tawg raws cov npoo nkhaus yam tsis muaj cov duab meej. Cov no cov ntxhia tsis muaj cov dav hlau tsis muaj zog thiab tawg irregularly.

Ib sab saum toj no, koj ua li cas txiav txim siab cleavage? Cleavage piav qhia txog yuav ua li cas cov pob zeb tawg rau hauv qhov chaw tiaj tus (feem ntau yog ib, ob, peb lossis plaub qhov chaw). Cleavage yog txiav txim siab los ntawm cov qauv siv lead ua ntawm cov ntxhia. Cubic: Thaum lub pob zeb tawg hauv peb cov lus qhia thiab cov cleavage cov dav hlau tsim cov kaum sab xis (90 degrees rau ib leeg).

Kuj tseem paub yog, 3 lub dav hlau cleavage yog dab tsi?

Hom cleavage

• Basal lossis pinacoidal cleavage tshwm sim thaum tsuas muaj ib lub dav hlau cleavage xwb.
• Cubic cleavage tshwm sim thaum muaj peb lub dav hlau cleavage sib tshuam ntawm 90 degrees.
• Octahedral cleavage tshwm sim thaum muaj plaub lub dav hlau cleavage nyob rau hauv ib lub siv lead ua.

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.
