Olivine ua tsis tshwm sim nrog cov ntxhia quartz . Quartz tau tsuas yog tsim los ntawm magmas uas muaj txheeb ze nplua nuj nyob rau hauv silica, thaum lub olivine Cov zaub mov tsuas yog tsim los ntawm magmas uas yog lean hauv silica, yog li quartz thiab olivine yog incompatible minerals.
Kuj tseem yuav paub yog, vim li cas olivine thiab quartz tsis zoo li yuav pom ua ke hauv tib lub pob zeb tsis zoo?
Nws yog vim li no quartz tsis yog pom nrog olivine , corundum, sodalite lossis lazurite. Cov zaub mov no tsuas yog tsis muaj tshuaj lom neeg ruaj khov ua ke . Tsis muaj cov ntxhia hauv magma - tsuas yog xoob atoms darting ncig. Raws li cov magma txias, cov atoms pib sib txuas ua ke tsim cov minerals.
Ib tug kuj yuav nug, qhov twg yog olivine nyob rau hauv lub ntiaj teb? Qhov chaw nyob Olivine feem ntau yog pom nyob rau hauv cov xim tsaus nti igneous pob zeb pom nyob rau hauv qhov chaw ntawm lub Lub ntiaj teb . Cov pob zeb no feem ntau nyob nyob rau hauv daim hlau tectonic thiab divergent phaj ciam teb. Olivine muaj lub siab crystallization kub uas ua rau nws yog ib qho ntawm thawj mineralize mus crystallize los ntawm lub Lub ntiaj teb kub.
Yog li ntawd, hom pob zeb twg yog olivine?
igneous pob zeb
olivine muaj pes tsawg cleavage?
Lub cev muaj zog. Qhov tshwj xeeb gravity thiab hardness ntawm lub cov olivines muaj npe nyob rau hauv Table. Muaj tsawg kawg yog ob qhov cleavages-piv txwv li, txoj kev nyiam sib cais raws cov kev qhia crystallographic nyiam (perpendicular mus rau a thiab b axes nyob rau hauv cov ntaub ntawv no) - ob qho tib si yog zoo-tsim nyob rau hauv cov hlau nplua nuj ntau yam.

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
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
Kuv puas tuaj yeem tso cov pob zeb lava rau hauv kuv lub qhov cub?
Koj tuaj yeem ntxiv cov pob zeb lava ua ntej lossis tom qab koj ntxiv cov cav. Siv cov pob zeb lava los ncuav rau ntawm lub hauv paus ntawm koj lub qhov cub thiab ib ncig ntawm koj lub lauj kaub kub. Qhov no tsis yog rau txheej saum toj ntawm txhua yam
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
