Txhaum qhov ua txhaum

1. Lub cev pob tawg feem ntau yog so thiab laim ntoom, tshwj xeeb tshaj yog nyob rau hauv cov kev taw qhia ntawm kev tawm tsam.

2. Muaj ntau feem ntau muaj khawb, cov kauj ruam, thiab sab tes tawv ntawm daim txhuam cev. Cov yoov tshiab (xws li mica, talc, chlorite) thiab zuaj lossis elongated kem pob zeb, cov zaub mov flaky, pob zeb, granules, quartz, calcite wafers thiab cov khoom ua rau lub pob txha lov thiab ob sab yog teem ze rau cov pob txha loj tib si.

3. Lub pob zeb tectonic hauv qhov txhaum yog qhov feem ntau yog breccia, mylonite, cov av nkos txhaum, thiab qee zaum cov txheej txheem lub teeb pom kev kuj pom.

4. Lub pob zeb ntawm ob sab ntawm pob txha nto tau tawg, rub thiab tawg vim muaj qhov ua kom muaj zog, ua rau qee lub tsev txuam nrog, xws li plume-zoo li fissures, cleavage, "hauv" cov qauv duab (suav nrog cov ua yuam kev thiab cov quav), me me revolving Tus Qauv, thiab lwm yam.

5. Lub ntsej muag tawg feem ntau tshwm sim hauv cov pab pawg, thaum sib ncawv mus rau ib leeg, txuas ntxiv mus ntev dua ntawm kev tawm tsam, thiab feem ntau tsim cov qauv tiling ntawm qhov profile.

6. thim rov qab kev txhaum (suav nrog kev ua txhaum, thim rov qab txhaum 辗 daim pam) yog qhov zam kev txhaum

Tensile txhaum

1, lub fracture nto yog ntxhib thiab tsis xwm, thiab cov duab tsis zoo. Tsawg dua khawb, tsawg dhau kev khawb, thiab feem ntau steeper da dej

2. Thaum lub pob tensile tshwm sim nyob rau hauv conglomerate, lub pob txha tawg feem ntau dhau los ntawm gravel yam tsis tau txiav lossis pluav.

3. Tsis muaj qhov pom tseeb qhov hloov ntawm qhov tshwm sim ntawm cov pob zeb tsim ntawm ob sab ntawm pob txha lov.

4. Lub pob zeb tectonic tsuas yog breccia, thiab cov av ntawm mylonite thiab txhaum yog qhov tsawg. Lub breccia yog loj heev nyob rau hauv loj thiab tsis muaj qhov tseem ceeb orientation

5, lub zog tensile feem ntau faib rau hauv pab pawg, tsim txoj kev ua txhaum tensile. Lawv cov kab ke sib txuas rau hauv ib lub dav hlau, thiab feem ntau ua rau hauv qab daus, ib theem zuj zus, thiab cov zoo li nyob hauv tshooj hla. Lub cev pob txha uas ua raws qhov "X" zoo li lub cev pob txha tawg, hu ua "Zigzag" kev tawg.

6, ib txwm txhaum yog tensile

Torsional txhaum

1. Lub cev pob txha tawg feem ntau yog du, tiaj, thiab qee zaum daim iav zoo li, feem ntau nrog cov kab ntau ntawm kab rov tav lossis ze qib. Lub txhaum ua tau ruaj khov thiab tus kab ua txhaum yog ncaj.

2. Muaj qee zaum qee cov khoom tshiab metamorphic cov ntxhia xws li siliceous, calcite thiab chlorite ntawm lub cev puas, tab sis tsis tshwm sim zoo li cov khoom txuam nrog sab hauv.

3. Lub tectonite feem ntau yog milled zoo heev, nrog breccia thiab mylonite, thiab muaj ib txoj kab nqaim ntawm lub zog ntawm lub cev. Tectonic pob zeb feem ntau tsim nyob rau hauv oblique faib thiab torsional txhaum cheeb tsam

4. Ntawm ob sab ntawm pob txha nto, lub pob zeb yog feem ntau nrog qee qhov kev sib tsoo thiab sib tsoo vim yog lub zog sib ntswg, "hauv" cov duab thiab cov qauv daws teeb meem me me.

5. Cov pob qij pob txha tawg feem ntau tshwm sim hauv pawg, ob pawg yog cov kab sib luag, thiab muaj tus "X" duab (feem ntau txiav rau hauv pob zeb diamond), qee zaum hauv kab geese

6 txhaum kev cai txhais lus yog qhov kev txhaum torsional

Hlob tomography

1. Ntawd yog, nws muaj lub zog ziab thiab muaj tus yam ntxwv torsional. Cov yam ntxwv ntawm kev hais saum toj saud thiab torsional pob txha lov tuaj yeem siv rau kev siv.

2. Cov khawb thiab cov kauj ruam taw qhia ntawm oblique slanting ntawm lub phaj siab yog feem ntau pom ntawm lub pob tawg. Qee qhov kev cuam tshuam yuav tshwm sim nyob rau hauv ob daim phiaj ntawm cov pob zeb, xws li kev sib tsoo, pinnate fissures, cleavage, "hauv" ceg ntoo thiab kauv tsim. Cov kev sib tshuam ntawm lub dav hlau axial, lub dav tawg thiab lub ntsiab ntawm lub ntsej muag ntawm cov qauv uas txuas no tsis zoo ib yam rau cov kab tawm ntawm lub ntsiab pob tawg, tsis pub mus tib seem rau txoj kab sib, tab sis nruab nrab ntawm ob, uas yog qhov nrawm ntawm kev sib deev puas

3 kev nias thiab torsion pob txha tawg feem ntau tshwm sim hauv pawg, ua rau geese nyob rau hauv kab thiab tiaj

4 lub rov qab txhais yuam kev thiab rov qab txhais cov txhaum yog tag nrho cov compression torsion cov kev ua yuam kev
