Pob zeb thiab cov Minerals

Pob zeb thiab cov minerals - yog ib tug tshwj xeeb compound khoom txoj kev lub ntiaj teb ua kiav txhab. Tag nrho cov khoom lub cev nyob rau hauv lub ntug thiab nyob rau hauv ntiaj teb ntawm ib tug uas zoo sib xws yam rau lub ntiaj teb tsim los ntawm pob zeb. Feem ntau cov kab lus "cov pob zeb" yog nrug tshaj lo lus "minerals", txij thaum lub qub tseem muaj li ntawm ntau hom ntawm cov zaub mov. Tag nrho cov pob zeb yuav txawv nyob rau hauv kev ntxhib los mos thiab cov qauv.

Kev ntxhib los mos - ib qhov chaw txheeb ze rau txhua tus lwm yam minerals, lawv tis nyob rau hauv ib qho kev txiav txim. Piv txwv li, thaum tsis muaj kev txiav txim nyob rau hauv no yog tsis pom, nws yog hu ua ib tug loj heev kev teeb tsa. Noj cov archaeologists hais tias lawv tau unearthed ib co kev txheej, nws txhais tau tias nyob rau hauv no qhov chaw fawm kib arrangement ntawm pob zeb (pob zeb thiab minerals) yog tsis tov, thiab superimposed on ib leeg.

Nyob rau hauv cov xwm, muaj zoo nkauj heev qhov chaw miraculous - nws underground qhov tsua ob loj thiab me me. Yog li ntawd, lawv npuas tsim tshwm sim nyob rau hauv lub pob zeb - xws voids tseg gases tso tawm los ntawm lub ntiaj teb. Ib tug shale pob zeb? Nws zoo li no nyob rau hauv lub hlais xwb xav tsis thoob! Qhov no daim yuav dawb lias thaum cov zaub mov ua tiaj tus zoo thiab ntev nyob rau hauv tib txoj kev coj.

Ib suam ntawm pob zeb muas thaum chiv thawj raws li nyob rau hauv peb tsis:

1. Thawj yug - lawv yog igneous.

2. Secondary yug - lawv yog sedimentary.

3. Metamorphic pob zeb - lawv muaj peev xwm tseem yuav hu ua hloov.
Igneous pob zeb thiab lwm yam minerals tawm yog tsim los ntawm solidification ntawm magma uas mus txog lub saum npoo av. Vim hais tias ib tug tej yam muaj pes tsawg tus ntawm tej yam kev mob yog lossi hloov kub thiab txawv tej yam tsim pob zeb nrog txawv zog thiab cov qauv. Igneous pob zeb raug muab faib ua effusive thiab sib sib zog nqus. Cov yav tas muaj ib tug ntau dua lub zog thiab ib tug tuab siv lead ua qauv. Lub nto moo tshaj plaws cov neeg sawv cev ntawm no hom ntawm cov pob zeb yog basalt thiab granite.

Sedimentary pob zeb raug tsim nyob rau hauv tus ntawm lwm yam tseem ceeb xws li kub hloov, lwm puag ncig - los nag, daus, hnub ci tawg thiab atmospheric gases. Sedimentary pob zeb raug muab faib ua organogenic, tshuaj thiab xoob.
Metamorphic pob zeb thiab lwm yam minerals tawm yog tsim raws li ib tug tshwm sim ntawm cov kev hloov nyob rau hauv tus nto qauv ntawm lub ntiaj teb. Qhov no tshwm sim thaum lub sij hawm cov av qeeg txhua, hloov ntawm lub ntiaj teb ua kiav txhab. Nyob rau hauv cov ntaub ntawv no qhov sib txawv khaubncaws sab nraud povtseg yog mixed breeds thiab hom - ob qho tag nrho sedimentary thiab igneous.
Txhais los ntawm lub Latin, mineral ( "miner") txhais tau tias "ore". Muaj pes tsawg leeg ntawm minerals - yog cov tshuaj hais tias yog tsim nyob rau hauv ntau yam complex lub cev thiab tshuaj dab. Minerals - lawm tshwm sim crystalline tshuaj. Tab sis qhov zoo ntawm tus siv lead ua yog tsis yog txhua txhua minerals.

Ib suam ntawm mineral keeb kwm raws li nyob rau hauv lawv cov kev faib mus rau hauv thawj thiab. Lub hom xws li cov neeg uas tau raug tsim nyob rau thaum lub sij hawm crystallization ntawm lub magma. Tej zaub mov muaj xws li mica, silica thiab sulfur. Secondary minerals tsim nyob rau hauv vivo thaum raug rau ntau yam lwm yam. Qhov no yuav ua tau ib tug precipitate ntawm ntsev dej dlaws los ntawm weathering thiab thawj kev puas tsuaj ntawm cov zaub mov los yog txawv residues tseem ceeb heev functions ntawm muaj sia nyob. Tej zaub mov muaj xws li ntau ntsev, sylvite thiab gypsum.

Raws li cov tshuaj nyob tus yeees ntawm cov zaub mov yuav ua tau haiv neeg (kub, pob zeb diamond, platinum, tooj liab), sulfide (ore tooj liab, mercury ore, taug txhuas), halides (poov tshuaj ntsev thiab pob zeb), oxides (tsim los ntawm raug cov pa: hematite, quartz, hlau ore) , carbonates (malachite, marble), sulfate (gypsum hais txog rau lawv), phosphate (apatite), silicate (chrysotile, talc, mica).
