Muaj peb loj hom ntawm pob zeb folding : monoclines, synclines, thiab anticlines. Ib tug monocline yog ib qho yooj yim khoov hauv lub pob zeb txheej kom lawv tsis kab rov tav lawm. Anticlines yog folded pob zeb uas arch upward thiab poob ntawm tus nruab nrab ntawm lub quav.
Tib neeg kuj nug, hom folds yog dab tsi?
Hom Folds
- Anticline: linear, strata ib txwm poob ntawm qhov chaw axial, qhov qub tshaj plaws nyob hauv nruab nrab.
- Syncline: linear, strata ib txwm poob mus rau axial center, yau tshaj strata nyob hauv nruab nrab.
- Antiform: linear, strata poob deb ntawm axial center, hnub nyoog tsis paub, los yog inverted.
Ib yam li ntawd, dab tsi ua rau pob zeb tawg? Cov quav tshwm sim los ntawm tectonic siab thiab kev nyuaj siab nyob rau hauv lub pob zeb thiab ntau dua li tawg, lawv quav . Lawv yooj yim pom los ntawm qhov poob ntawm kab rov tav ntawm lub strata. Thaum tectonic rog ua rau sedimentary pob zeb yog ib tug xov tooj ntawm cov yam ntxwv daim ntawv.
Tsuas yog li ntawd, hom folds hauv geology yog dab tsi?
hom quav Peb daim ntawv ntawm folds : syncline, anticline, thiab monocline. Ib qho antiline yog ib quav uas yog convex upward, thiab ib tug syncline yog ib quav uas yog concave upward. Ib qho anticlinorium yog ib qho tshuaj tiv thaiv kab mob loj uas muaj menyuam yaus quav yog superimposed, thiab ib tug synclinorium yog ib tug loj syncline uas me quav yog superimposed.
Dab tsi yog symmetrical fold?
txhais. Hauv quav . A symmetrical quav yog ib qho uas lub dav hlau axial yog ntsug. Ib asymmetrical quav yog ib qho uas lub dav hlau axial yog inclined. Ib overturned quav , los yog overfold, muaj lub dav hlau axial inclined mus rau qhov uas lub strata ntawm ib ceg ceg yog rov qab .…

Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb

Extrusive igneous pob zeb
Cov pob zeb hauv av twg tuaj yeem tsim cov pob zeb zoo li lub raum?
Hematite (los yog haematite) Kuj tseem muaj ntau hom hematite, qee yam yog: raum ore, ib qho loj, botryoidal (lumpy) lossis reniform (lub raum zoo li tus) daim ntawv; specularite, micaceous (flaky) daim ntawv; oolitic, ib daim ntawv sedimentary tsim los ntawm cov nplej me me; liab ochre, ib daim ntawv liab earthy
