Qhov sib txawv tseem ceeb ntawm kev tawg thiab tawg yog qhov kev tawg yog qhov uas cov pob zeb tawg raws nws lub dav hlau tsis muaj zog thaum tawg yog tawg ntawm cov pob zeb thaum atomic bonding zoo meej, thiab tsis muaj qhov tsis muaj zog.
Cleavage thiab pob txha yog cov yam ntxwv ntawm lub cev uas pab txhawm rau txheeb xyuas cov pob zeb hauv av. Cov lus cleavage thiab tawg yog cov lus siv ntau heev uas peb siv hauv ntau lub ntsiab lus. Txawm li cas los xij, nws yog thaum txheeb xyuas cov zaub mov uas cov lus no tau siv ua ke vim cov no yog cov yam ntxwv ntawm lub cev ntawm cov zaub mov thiab pab hauv kev txheeb xyuas cov pob zeb vim tias cov ntxhia sib txawv muaj ntau hom pob txha thiab cleavages. Raws li, xws li xim, ntom, lustre, thiab lwm yam., tawg thiab cleavage dhau los ua lub hauv paus ntawm kev sib txawv ntawm cov minerals sib txawv.
Cleavage yog dab tsi?
Cleavage yog yam uas cov pob zeb tawg raws nws lub dav hlau tsis muaj zog. Nws tshwm sim raws cov dav hlau du uas sib npaug rau thaj tsam ntawm kev sib txuas tsis muaj zog. Tsis tas li ntawd, nws tuaj yeem tshwm sim hauv ntau txoj hauv qab no:
- Cleavage in one direction. i.e. muscovite
- Nyob rau hauv ob txoj kev. i.e. feldspar
- Nyob rau hauv peb txoj kev - cubic. i.e. halite, and
- Cleavage hauv peb txoj kev - rhombohedral. i.e. calcite.
Daim duab 01: Cleavage nyob rau hauv ob txoj kev
Kev lig kev cai, peb siv cov cuab yeej no txhawm rau txheeb xyuas cov zaub mov sib txawv. Nws yog qhov muaj txiaj ntsig zoo hauv kev txheeb xyuas cov khoom siv tes thiab kev kuaj xyuas cov pob zeb hauv microscopic.
Ntxiv mus, nws tseem ceeb hauv kev txiav gemstones. Tsis tas li ntawd, nws yog ib qho tseem ceeb hauv kev lag luam hluav taws xob. Piv txwv li, Synthetic single crystals ntawm cov ntaub ntawv semiconductor feem ntau yog muag raws li nyias wafers uas yooj yim dua rau cleave.
Fracture yog dab tsi?
Fracture yog qhov tawg ntawm cov pob zeb thaum atomic bonding zoo meej, thiab tsis muaj qhov tsis muaj zog. Nws tshwm sim raws nkhaus nto yam tsis muaj cov duab meej. Cov zaub mov uas muaj cov cuab yeej no tsis muaj qhov tsis muaj zog. Ntxiv mus, lawv tawg irregularly.
Daim duab 02: iav tawg
Tsis tas li ntawd, qhov tawg yog qhov cim tseg ntawm lub pob zeb thaum nws tawg, tab sis cov atomic bonding ntawm atoms hauv nws cov qauv crystalline qhia tias tsis muaj zog thiab zoo tag nrho. Xws li cov zaub mov, thaum muab tso rau hauv kev ntxhov siab, tawg rau hauv daim, tsis muaj ob qho tib si. Tsis tas li ntawd, qhov tawg yog qhov yooj yim yog conchoidal lossis non-conchoidal. Ib qho piv txwv ntawm conchoidal tawg yog lub iav tawg; nyob ntawd peb tuaj yeem pom cov qauv ncig hauv cov khoom tawg. Whereas, thaum quarts tawg, tej daim qhia tsis-conchoidal tawg tsis muaj tus qauv ruaj.
Qhov txawv ntawm Cleavage thiab Fracture yog dab tsi?
Cleavage thiab tawg yog ob yam khoom ntawm cov zaub mov. Qhov sib txawv ntawm qhov cleavage thiab tawg yog qhov cleavage yog yam uas cov pob zeb tawg raws nws lub dav hlau tsis muaj zog thaum tawg yog tawg ntawm cov ntxhia thaum atomic bonding zoo tag nrho, thiab tsis muaj zog.
Raws li lwm qhov sib txawv tseem ceeb ntawm kev sib cais thiab pob txha, peb tuaj yeem hais tias kev sib cais tsis tu ncua, tab sis pob txha tsis sib xws. Raws li cov piv txwv ntawm cov minerals nrog cleavage peb muaj peev xwm muab halite, calcite, gypsum, thiab lwm yam. Quartz yog ib tug mineral uas qhia fracture es tsis cleavage.
Cov ntsiab lus ntxiv tau muab rau hauv cov duab hauv qab no ntawm qhov sib txawv ntawm qhov sib cais thiab tawg.
Summary – Cleavage vs Fracture
Cleavage thiab pob txha yog cov yam ntxwv ntawm lub cev uas pab txhawm rau txheeb xyuas cov pob zeb hauv av. Qhov sib txawv tseem ceeb ntawm cleavage thiab pob txha yog qhov cleavage yog qhov uas cov pob zeb tawg ua rau nws lub dav hlau tsis muaj zog thaum tawg yog qhov tawg ntawm cov pob zeb thaum atomic bonding zoo meej, thiab tsis muaj qhov tsis muaj zog.
