Dab tsi kiag li Lub sijhawm luv luv yog sawv cev los ntawm qhov tsis sib haum xeeb ntawm lub hauv paus ntawm pob zeb txheej G ? Los ntawm 75 mus rau 150 lab xyoo 9.
Yog li ntawd, yog pob zeb txheej kuv laus dua lossis yau dua txheej H?
Ua ntej, peb paub los ntawm lub hauv paus ntsiab lus ntawm superposition ntawd pob zeb txheej F yog laus dua E, E yog laus dua D, D yog laus dua C, thiab C yog laus dua B. Qhov thib ob, peb saib qhov ntawd pob zeb txheej H (uas yog igneous intrusion) txiav rau hauv pob zeb txheej B-F. Nws yog li ntawd hluas dua B-F.
Tsis tas li ntawd, dab tsi yog qhov kev txiav txim ntawm cov xwm txheej los ntawm tus hlob mus rau tus yau? Lub hauv paus ntsiab lus ntawm superposition hais tias lub hlob sedimentary pob zeb units yog nyob rau hauv qab, thiab cov tus yau nyob rau saum. Raws li qhov no, txheej C yog hlob , ua raws li B thiab A. Yog li tag nrho ib ntus ntawm xwm txheej yog raws li nram no: Txheej C tsim.
Ua raws li qhov no, dab tsi yog 4 hom kev tsis sib haum xeeb?
Muaj plaub hom kev tsis sib haum xeeb:
- Kev tsis sib haum xeeb.
- Paraconformities.
- Angular Unconformities.
- Kev tsis sib haum xeeb.
Pob zeb strata qhia li cas lub sij hawm geological?
Txheej, lossis txaj txaj, yog qhov pom tseeb tshaj plaws ntawm sedimentary pob zeb . Txoj cai ntawm Superposition no yog qhov tseem ceeb rau kev txhais lub ntiaj teb keeb kwm, vim hais tias ntawm ib qho chaw nws qhia cov hnub nyoog txheeb ze ntawm pob zeb txheej thiab cov pob txha hauv lawv. Txheej pob zeb tsim thaum cov khoom nyob ntawm dej los yog huab cua.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Lub hauv paus ntsiab lus twg ntawm kev txheeb ze koj tau siv los txiav txim siab seb pob zeb txheej H yog laus dua lossis hluas dua txheej?
Lub hauv paus ntsiab lus ntawm superposition yog yooj yim, intuitive, thiab yog lub hauv paus rau cov txheeb ze hnub nyoog sib tam. Nws hais tias cov pob zeb nyob hauv qab lwm cov pob zeb yog cov laus dua li cov pob zeb saum toj no
Lub pob zeb twg sawv cev rau kev kho mob?
Agate - Lub pob zeb zoo nkauj no muab kev tiv thaiv dav dav thiab kho, ua kom muaj siab tawv, pab txhawb kev ntseeg tus kheej thiab lub zog thiab txhawb nqa lub neej ntev. Amber - ua kom muaj tswv yim zoo, nws pab koj lees txais kev hloov pauv thiab ua raws li koj txoj kev npau suav. Kho pob zeb uas soothing, calming thiab coj tus cwj pwm zoo
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
Lub pob zeb foliated twg yog qhov qis tshaj plaws metamorphic pob zeb?
slate Ua li no, marble puas yog qib qis metamorphic pob zeb? Qee qhov piv txwv ntawm non-foliated Cov pob zeb metamorphic yog marble , quartzite, thiab hornfels. Marble yog metamorphosed limestone. Thaum nws tsim, cov calcite crystals yuav loj hlob tuaj, thiab tej yam sedimentary textures thiab fossils uas muaj tam sim no raug puas tsuaj.
