Carbonate pob zeb: piav qhia, nta, qauv thiab kev faib

Nyob rau lub ntiaj teb, muaj ntau li ntau sib txawv pob zeb. Ib txhia ntawm lawv muaj zoo sib xws cov tsos mob, li ntawd, lawv tau ua ke nyob rau hauv pawg loj. Piv txwv li, ib tug ntawm lawv - yog carbonate pob zeb. Lawv piv txwv thiab cais nyeem tsab xov xwm.

Classification los ntawm keeb kwm

Carbonate pob zeb raug tsim nyob rau hauv ntau txoj kev. Muaj plaub txoj kev rau txoj kev ua no hom ntawm cov pob zeb.

• Ntawm tshuaj nag lossis daus. Yog li muaj dolomite, marl, limestone thiab siderite.
• Ntawm biogenic sediments tsim xws breeds li algae thiab coral limestone.
• Tsim los ntawm cov khib nyiab ntawm sandstones thiab conglomerates.
• Recrystallized pob zeb - nws yog ib co hom dolomite thiab marble.

Qauv carbonate pob zeb

Ib tug ntawm cov tseem ceeb tshaj plaws tsis uas yog npaum li cas tsim nyog rau pob zeb ntau lawm thiab ua, yog lawv cov qauv. Qhov tseem ceeb tshaj nam ntawm carbonate pob zeb qauv - nws yog lawv graininess. Qhov kev xaiv no cais lub pob zeb rau hauv ob peb hom:

• Ntxhib-grained.
• Ntxhib.
• Medium-grained.
• Fine-grained.
• Fine-grained.

zog

Vim lub fact tias muaj ntau yam pob zeb carbonate hom, lawv txhua tus nws muaj nws tus kheej lub zog, rau cov uas nws yog heev tseem ceeb nyob rau kev lag luam thiab raug. Yuav ua li cas yog lub cev thiab tshuaj thaj chaw ntawm carbonate pob zeb paub rau cov neeg?

• Zoo solubility nyob rau hauv acids. Lub limestones yog yaj nyob rau hauv ib tug txias lub xeev, thiab magnesite thiab siderite - tsuas yog thaum rhuab. Txawm li cas los, qhov tshwm sim yog zoo sib xws.
• High te kuj thiab zoo hluav taws kuj - undoubtedly lub tseem ceeb tshaj plaws zoo ntawm ntau carbonate pob zeb.

limestone pob zeb

Tej carbonate pob zeb muaj calcite minerals magnesite, siderite, dolomite, raws li zoo raws li ntau yam impurities. Vim sib txawv nyob rau hauv nyob tus yeees ntawm no loj pab pawg neeg ntawm cov pob zeb no tau muab faib mus rau hauv peb lub me sawv daws yuav. Ib tug ntawm lawv - limestone.

Lawv lub ntsiab tivthaiv - calcite, thiab, nyob ntawm seb lub impurities lawv muab faib ua xuab zeb, av nplaum, silica thiab lwm tus neeg. Lawv muaj sib txawv textures. Lub fact tias cov kab nrib pleb rau lawv nqaws yuav pom cov ripple qhab nia thiab raindrops, ntsev muaju, uas yog soluble thiab me kab nrib pleb. Limestone tej zaum yuav txawv nyob rau hauv cov xim. Lub hom xim yog beige, grey los yog daj, thiab cov impurities yog liab, brownish los yog greenish zas.

Cov feem ntau limestone pob zeb yog raws li nram no:

• Mel - heev mos mos pob zeb, uas yog yooj yim pounded. Nws yuav ua tau tawg caj npab los yog zom rau hauv ib lub hmoov. Nws yog suav tias yog ib daim ntawv ntawm limestone cemented. Mel - nqi raw khoom siv nyob rau hauv qhuav ntawm MAAs tsev ntaub.
• Calcareous tufa - ntxeem tau friable pob zeb. Nws yog txaus yooj yim los tsim. Yuav luag tib yam tseem ceeb thiab coquina.

dolomite pob zeb

Dolomite - ib lub pob zeb dolomite mineral nyob rau hauv cov ntsiab lus ntawm ntau tshaj 50%. Feem ntau, lawv muaj impurities ntawm calcite. Vim li no, koj yuav tau saib ib co ntawm cov zoo sib xws thiab sib txawv ntawm ob pab neeg ntawm cov pob zeb: lub sij dolomite thiab limestone.

Dolomite limestone txawv ntawm cov neeg uas muaj ib tug ntau pronounced ci. Lawv yog cov tsawg soluble nyob rau hauv acids. Txawm lub seem ntawm cov organic teeb meem yog ntau npaum li cas tsis tshua muaj heev nyob rau hauv lawv. Coloring dolomite qhia tau hais tias greenish, pinkish, brownish thiab yellowish ntxoov.

Yuav ua li cas dolomitic pob zeb yog feem ntau? Nws yog, ua ntej ntawm tag nrho cov, muab pov - denser pob zeb. Nyob rau hauv tas li ntawd, muaj Greiner mos liab xim, nws yog dav siv nyob rau hauv sab hauv tsim. Teruel - kuj yog ib tug zoo ntawm dolomite. Lub pob zeb no yog zoo tshaj plaws nyob rau hauv uas yog nyob rau hauv cov xwm xwb nyob rau hauv dub, thaum lub seem hom ntawm no pab pawg neeg yog xim nyob rau hauv lub teeb xim.

Carbonate-av nplaum pob zeb, los yog marl

Muaj pes tsawg leeg ntawm carbonate cov pob zeb ntawm no hom muaj xws li ib tug ntau ntawm cov av nplaum, namely - ze li ntawm 20 feem pua. Los ntawm nws tus kheej, ib tug tsiaj nrog no lub npe muaj ib tug tov muaj pes tsawg leeg. Nyob rau hauv nws cov qauv ib txwm tam sim no aluminosilicates (av nplaum Feldspar decomposition khoom) raws li tau zoo raws li calcium carbonate, nyob rau hauv tej daim ntawv. Carbonate-av nplaum pob zeb yog hloov txuas ntawm limestones thiab av nplaum. Marl yuav muaj ib tug txawv qauv, khoom los yog tuab, xoob los yog earthy. Feem ntau cov feem ntau lawv tshwm sim nyob rau hauv daim ntawv ntawm ob peb khaubncaws sab nraud povtseg, txhua tus uas yog yus muaj los ntawm ib qho kev muaj pes tsawg leeg.

High carbonate pob zeb no hom yog siv nyob rau hauv qhuav ntawm crushed pob zeb. Marl, muaj impurities ntawm gypsum tsis yog tus nqi, yog li no zoo nws yog yuav luag mined. Yog hais tias koj sib piv qhov no zoo ntawm cov pob zeb nrog rau lwm yam, ntau dua lwm yam nws yog zoo li shale thiab siltstone.

limestone

Tej kev faib comprises carbonate pob zeb qhab hu ua "limestone". Pob zeb, uas tau muab nws lub npe tau lug siv nyob rau hauv ntau yam teb ntawm kev lag luam. Limestone - lub feem ntau nrov yug nyob rau hauv cov pab pawg neeg. Nws muaj ib tug xov tooj ntawm zoo zoo, ua tsaug rau uas yog dav siv.

Muaj limestone ntawm txawv xim. Nws tag nrho cov nyob rau ntau npaum li cas ntawm lub pob zeb muaj hlau oxides, vim hais tias cov tebchaw yog pleev xim rau limestone nyob rau hauv ntau xim. Feem ntau cov feem ntau nws yog xim av, daj thiab liab hues. Limestone - lub pob zeb yog txaus ntom, nws cov lus dag nyob rau hauv lub hauv av nyob rau hauv daim ntawv ntawm cov loj loj khaubncaws sab nraud povtseg. Tej zaum tsim tag nrho roob, uas yog ib qhov tseem ceeb ntawm lub pob zeb no. Xauj khaubncaws sab nraud povtseg piav saum toj no yuav ua tau nyob deb deb ntawm tus dej ntws nrog ntxhab lub tsev txhab nyiaj. Ntawm no lawv yuav saib tau zoo heev.

Limestone muaj ib tug xov tooj ntawm thaj chaw uas paub qhov txawv los ntawm lwm pob zeb. Paub qhov txawv nruab nrab ntawm lawv yooj yim heev. Qhov yooj yim txoj kev uas koj yuav ua tau nyob rau hauv tsev - ib tug nco nyob rau hauv nws ib tug me ntsis vinegar, ib tug ob peb ncos. Tom qab ntawd poslyshatsya hissing suab thiab roj evolution pib. Nyob rau hauv lwm cov breeds xws tshuaj tiv thaiv acetic acid yog tsis tam sim no.

kev siv cov

Txhua carbonate pob zeb tau thov nyob rau hauv tej tshav pob ntawm kev lag luam. Yog li ntawd, nrog rau limestone dolomite thiab magnesite yog siv nyob rau hauv metallurgy raws li ib tug flux. Cov no yog cov tshuaj uas yog siv nyob rau hauv lub smelting ntawm co los ntawm ore. Nrog lawv pab ores txo melting kub, uas yuav pab tau yooj yim cais co ntawm pov tseg pob zeb.

Tej carbonate pob zeb, cwj mem av dawb, paub rau tag nrho cov xib fwb thiab cov me nyuam kawm ntawv, vim hais tias nrog nws pab, sau rau lub Rooj Tswjhwm Saib. Nyob rau hauv tas li ntawd, cov cwj mem av dawb whitewash lub phab ntsa. Vim hais tias nws yog tseem manufactured hmoov dentifrice, tab sis tam sim no qhov no yog tsis yooj yim kom tau ib tug hloov pastes.

Limestone yog siv los tsim dej qab zib, cov nitrogenous chiv thiab calcium carbide. Carbonate cov pob zeb ntawm ib yam ntawm cov hom views, xws li limestone, siv rau kev tsim kho ntawm lub tsev, industrial cov chaw, raws li zoo raws li txoj kev. Nws los ua ntau raws li ib tug txojkev khoom thiab pob zeb ua sau ua ib pawg. Nws kuj yog siv los tsim pub pab nrog cov zaub mov thiab limestone av saturation. Los ntawm nws ua tau ib lub tsev blocks, piv txwv li, gravel thiab rubble. Nyob rau hauv tas li ntawd, qhov no ib yam tsiaj ua MAAs thiab txiv qaub, uas yog dav siv nyob rau hauv ntau hom industries, xws li nyob rau hauv lub metallurgical thiab tshuaj.

lolus

Muaj xws li ib tug ntau yam ntawm pob zeb raws li lolus. Lawv muaj peev xwm, uas enables lawv los tuav cov dej, nkev, roj, thiab tig rau ib tug thaum muab lawv rov qab mus txoj kev loj hlob. Yog vim li cas yog no mas? Lub fact tias cov pob zeb muaj ib tug ntxeem tau qauv, thiab qhov no zoo heev muaj nuj nqis. Nws yog ua tsaug rau tus porosity, lawv yuav haum ib tug loj tus naj npawb ntawm cov roj thiab cov nkev.

Carbonate pob zeb - zoo lolus. Qhov zoo tshaj plaws nyob rau hauv nws cov pab pawg neeg yog dolomite, limestone thiab cwj mem av dawb. 42 rau ib xees ntawm siv roj reservoir thiab cov roj reservoir 23 feem pua - carbonate. Cov pob zeb nyob ob qhov chaw tom qab clastic.
