argillite pob zeb

Argillite yog lub npe muab rau cov pob zeb uas tau tshwm sim los ntawm lub cev qhuav dej, nias thiab rov ua cov av nplaum. Raws li txoj cai, lub pob zeb tsis suav tias yog ib qho khoom plig muaj nqis thiab koj tsis zoo li yuav pom cov hniav nyiaj hniav kub nrog nws. Txawm tias muaj tseeb hais tias av nkos yog heev zoo sib xws nyob rau hauv muaj pes tsawg leeg rau av nplaum, nws yog tseem nyuaj thiab resistant rau soaking.

piav qhia

Cov pob zeb hauv av belongs rau sedimentary formations, txij li thaum nws muaj pes tsawg leeg yog tsim los ntawm cov pob zeb puas lawm nyob rau hauv lub zog ntawm tej yam ntuj tso phenomena nyob rau hauv tus ntawm kub kub thiab siab.

Cov qauv ntawm cov pob zeb hauv av tsis yog homogeneous, tab sis muaj cov txheej txheem ntawm cov xuab zeb, hmoov av thiab av nplaum. Nyob rau hauv qhov tseeb, txawm tias qhov no muaj pes tsawg leeg, lub pob zeb yog suav hais tias yog heev ruaj. Ntawm Mohs nplai, nws tau txais 4 cov ntsiab lus.

Lub ntsiab ntxoov ntxoo ntawm yug:

• xiav-grey;
• dub;
• grey-dub;
• teeb.

Cov luster ntawm cov ntxhia yog resinous, nrog ib tug silky nto. Lub pob zeb nws tus kheej yog qhov yooj yim heev. Yog tias kho tsis raug, nws tuaj yeem yooj yim crumble.

Deposits thiab mining ntawm mudstone

Lub pob zeb tseem ceeb yog nyob rau ntawm ib pawg ntawm cov Islands tuaj hauv British Columbia. Nws paub tias ntau pua xyoo dhau los pob zeb tau siv rau kev tsim cov cuab yeej, cov khoom siv thiab lwm yam khoom siv, lub hom phiaj tseem ceeb ntawm kev saib xyuas lub neej thiab kev tshem tawm cov kev cai. Tsis tas li ntawd, ntau yam tseem ceeb ntawm argillite - catlinite - tau siv los ntawm Sioux Indian cov neeg nyob rau sab qaum teb Tebchaws Meskas thiab sab qab teb Canada los tsim lawv cov cim kab lis kev cai - cov yeeb nkab ntawm kev thaj yeeb, nrog kev pab los ntawm kev cog lus kev thaj yeeb thiab kev ua koob tsheej tau ua. .

Txoj kev tseem ceeb ntawm argillite mining yog quarrying. Rau qhov no, cov cuab yeej excavation txheem yog siv, thiab tag nrho cov pob zeb hauv av pom tau tam sim ntawd hloov mus rau kev tshuaj xyuas, kev tshawb fawb thiab kev ua haujlwm. Tsis tas li ntawd, huab cua qhuav tshav ntuj yuav tsum tau saib xyuas thaum lub sij hawm excavations, txij li thaum me ntsis nce nyob rau hauv cov av noo, av nkos kiag li crumbles thiab excavations nyob rau hauv cov ntaub ntawv no yog irrational.

Daim ntawv thov

Argillite yog siv nyob rau hauv ntau qhov chaw, tab sis tsuas yog nyob rau hauv kev tsim kho. Vim lub melting ntawm cov ntxhia nyob rau hauv high kub, nws yog ntxiv rau ntau yam mixs los txhim kho nws astringent zog.

Tsis tas li ntawd, lub pob zeb yog siv rau sculpting hniav ntsiab ntawm sab hauv thiab sab nrauv. Yog hais tias tag nrho cov hauj lwm ua tiav kom raug thiab kev xav tau pom, ces vim yog cov txheej txheem heterogeneous ntawm argillite, koj tuaj yeem tsim stucco molding zoo nkauj heev hauv cov qauv, cov kab du, thiab txawm tias cov duab ntawm tib neeg thiab tsiaj txhu.

Argillite kuj tseem nrov heev ntawm cov sculptors thiab artists. Txawm tias muaj tseeb hais tias cov ntxhia yog heev nyuaj rau kev ua hauj lwm nrog (nws yog ib qho nyuaj rau txheej txheem), nws yog ib qhov zoo rau tsim sculptures thiab peb-seem paintings, uas yog varnished thaum kawg thiab saib amazing.
