Rhombohedral Thaum a ntxhia tawg nyob rau hauv peb cov lus qhia thiab cov cleavage cov dav hlau tsim cov kaum sab xis uas tsis yog 90 degrees. Cov duab tsim yog hu ua rhombohedron. Thaum a ntxhia tawg nyob rau hauv ib qho kev taw qhia, tawm hauv ib qho chaw tiaj tus ( cleavage dav hlau).

Kuj paub yog, qhov txawv ntawm pob txha thiab cleavage nyob rau hauv ib tug ntxhia yog dab tsi?

pob txha yog tus yam ntxwv txoj kev a ntxhia tawg. Cov qhov sib txawv ntawm cleavage thiab tawg yog tias cleavage yog qhov tawg ntawm lub ntsej muag siv lead ua qhov twg lub ntsej muag tshiab siv lead ua yog tsim qhov twg ntxhia tawg, hos tawg yog "chipping" ntawm a ntxhia . Tsis sib xws - A tawg uas tawm ntawm qhov ntxhib los yog tsis xwm yeem.

Tom qab ntawd, lo lus nug yog, cov pob zeb puas tuaj yeem muaj qhov tawg thiab tawg? Cleavage thiab tawg txawv qhov ntawd cleavage yog qhov tawg ntawm lub ntsej muag siv lead ua qhov twg lub ntsej muag tshiab (ua rau lub dav hlau du) yog tsim, whereas tawg yog "chipping" zoo li ib ntxhia . Tag nrho cov ntxhia nthuav tawm a tawg , txawm cov uas nthuav tawm cleavage.

Tom qab, lo lus nug yog, dab tsi yog cleavage nyob rau hauv 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.

Puas yog cov pob zeb sedimentary puas muaj cleavage?

Cleavage , nyob rau hauv structural geology thiab petrology, piav txog ib hom phiaj pob zeb feature uas tsim los ntawm deformation thiab metamorphism. Qhov tseem ceeb deals nrog igneous thiab sedimentary pob zeb thaum theem nrab deals nrog pob zeb uas undergo metamorphism raws li qhov tshwm sim ntawm deformation.
