Txoj kev ntxhia reflects lub teeb los ntawm nws nto yog hu ua dawb paug uas tau piav qhia tias yog xim hlau lossis nonmetallic. Luster. Yuav ua li cas ntxhia hnov rau qhov kov yog hu ua . Kev ntxhib los mos. Thiab cov ntxhia dawb paug yog xim ntawm ntxhia thaum tawg thiab hmoov.
Ib yam li ntawd, cov ntxhia xav li cas?
Geologists siv lub cev lub cev los txheeb xyuas cov ntxhia . Piv txwv li, tus ------ ntawm ntxhia yog tshwm sim los ntawm tus muaj cov kab sib txawv. Cov txoj kev a ntxhia reflects lub teeb los ntawm nws nto yog hu ua ------, uas yog piav raws li metallic thiab nonmetallic. Yuav ua li cas ib tug ntxhia xav rau tus kov yog hu-----.
Ib tug kuj yuav nug, dab tsi yog qhov tseeb crystalline qauv ntawm cov ntxhia? Nrog ib meej tshuaj muaj pes tsawg leeg (txhua lub sij hawm peb pom tib yam ntxhia nws muaj tib yam tshuaj muaj pes tsawg leeg uas tuaj yeem qhia tau los ntawm cov tshuaj formula). thiab tus yam ntxwv crystalline qauv (Atoms yog teem rau hauv ntxhia nyob rau hauv ib qho kev txiav txim tshwj xeeb).
Hauv qhov no, qhov ntsuas qhov yooj yim npaum li cas ntawm cov ntxhia tuaj yeem khawb?
hardness yog ntsuas qhov yooj yim npaum li cas ib qho ntxhia tuaj yeem khawb.
Dab tsi yog tshwm sim los ntawm muaj cov kab hauv cov ntxhia?
Luster. Txoj kev a ntxhia reflects lub teeb los ntawm nws qhov chaw. Xim. Qhov no yog tshwm sim los ntawm lub xub ntiag ntawm txawv kab kawm.

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
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
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
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.
