Hematite (los yog hematite)
Kuj muaj ob peb daim ntawv Ntawm cov hematite, qee qhov yog: cev ore , loj heev, botryoidal (lumpy) los yog reniform ( lub raum zoo li ) daim ntawv ; specularite, micaceous (flaky) daim ntawv ; oolitic, ib tug sedimentary daim ntawv muaj li ntawm me me rounded nplej; liab ochre, liab earthy daim ntawv.
Ntawm no, dab tsi yog crystal daim ntawv ntawm ib tug ntxhia?
Hauv mineralogy , Crystal cwj pwm yog tus yam ntxwv sab nraud puab ntawm tus kheej siv lead ua los yog siv lead ua pab pawg. Ib leeg Crystal tus cwj pwm yog ib qho kev piav qhia ntawm nws cov general puab thiab nws crystallographic daim ntawv , ntxiv rau qhov tsim tau zoo npaum li cas daim ntawv yog. Paub qhov tus cwj pwm tuaj yeem pab txheeb xyuas a ntxhia.
Ib yam li ntawd, dab tsi yog cov ntxhia nrog cov txiv hmab txiv ntoo zoo li cov qauv siv lead ua? Ib tug botryoidal kev ntxhib los mos los yog ntxhia cwj pwm yog ib qho uas tus ntxhia muaj ib tug globular sab nraud daim ntawv zoo li ib pawg ntawm txiv kab ntxwv (botrys nyob rau hauv ancient Greek). Qhov no yog ib qho qauv rau ntau tus cov ntxhia , tshwj xeeb tshaj yog hematite, lub classical pom zoo.
Tsuas yog li ntawd, hom pob zeb hauv av yog hematite?
Hematite yog ib qho ntawm ntau tshaj cov ntxhia nyob rau hauv lub ntiaj teb nto thiab nyob rau hauv qhov ntiav crust. Nws yog hlau oxide nrog cov tshuaj muaj pes tsawg leeg ntawm Fe2O3. Nws yog ib hom pob zeb-forming ntxhia pom nyob rau hauv sedimentary, metamorphic, thiab igneous pob zeb ntawm qhov chaw thoob plaws ntiaj teb. Hematite yog qhov tseem ceeb tshaj plaws ntawm cov hlau.
Lub raum ore yog dab tsi?
Lub raum Ore (Hematite) yog cov ntxhia uas "hlau (Fe)" thiab "oxygen (O)" txuas nrog. Nws raug cais raws li hom "Oxide Minerals". Nws kuj yog nto moo raws li ib tug ore los ntawm qhov twg hlau tuaj yeem sau tau.

Dab tsi yog 3 hom folds uas tuaj yeem tsim hauv pob zeb?
Muaj peb hom pob zeb folding: monoclines, synclines, thiab anticlines. Ib tug monocline yog ib qho yooj yim khoov nyob rau hauv cov pob zeb txheej kom lawv tsis kab rov tav. Anticlines yog folded pob zeb uas arch upward thiab poob deb ntawm qhov chaw ntawm lub quav
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
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
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
