Nrog "Guiyang tshav dav hlau chav dej marble dab dej tag nrho ntawm cov pob txha" maj nrawm mus rau qhov kev tshawb fawb kub ntawm Weibo, thawj marble ntawm 100 yuan / square tsis zoo heev rau muag, tam sim no nws tau muag ntau dua 1, 000 yuan / square! Tus nqi tam sim ntawd nce 10 npaug!
Paleontologists thiab geologists nrhiav pom tias cov hniav marble slabs ntawm chav dej hauv Guiyang tshav dav hlau, Guizhou, tau npog nrog pob txha pob txha. Nws tau raug txheeb xyuas tias yog genus Silurian thaum ntxov Silurian 439 lab xyoo dhau los.
Shen Shuzhong, tus kws tshaj lij ntawm Suav Academy ntawm Kev Tshawb Fawb thiab tus xibfwb ntawm Tsev Kawm Ntawv ntawm Geographical Sciences ntawm Nanjing University, tau hais hauv kev xam phaj nrog tus neeg sau xov xwm los ntawm Central Chaw Nres Tsheb tias cov pob txha pob txha no muaj nyob thoob plaws. Nws tsis yog qhov xav tsis thoob tias cov fossils no muaj ntau heev. Pom tau tias hom fossil no, yuav muaj pob txha pob txha nyob hauv av hauv qee qhov chaw ua yeeb yam, chav tsev thiab lwm qhov chaw. Qhov no tshwm sim heev thiab nws tsis yog xav tsis thoob.'
"Qhov no puas yuav tsum tau muab tshem tawm los tiv thaiv?" Hauv kev teb, Xib Fwb Shen tau hais tias, "Qhov fossil no nws tus kheej tau nthuav dav thiab ntau heev. Qhov tseeb, nws yog ib qho khoom siv hauv tsev zoo tib yam."
Seashell Flowers Marble (dub fossils marble) yog tsim nyob rau hauv Guizhou, Sichuan, Suav teb, thiab yog tsuas yog siv rau architectural kho kom zoo nkauj, xws li siv monumental vaj tse, tsev so, exhibition halls, theaters, khw malls, tsev qiv ntawv, tshav dav hlau, chaw nres tsheb, thiab lwm yam. , cov phab ntsa sab hauv tsev, lub tog raj kheej, thiab lwm yam ntawm cov tsev loj loj Cov khoom siv rau hauv av thiab lwm qhov chaw kuj tuaj yeem siv rau stair railings, cov chaw pabcuam, lub ntsej muag lub ntsej muag, phab ntsa tiab, qhov rais sills, skirting boards, thiab lwm yam.
Zhan Gengshen, tus tuav ntaub ntawv ntawm Geological Society ntawm Jiangsu Xeev, tau hais tias lub hnub nyoog ntawm cov pob txha tsim nyob deb heev ntawm peb, tab sis hauv lub neej tiag tiag nws nyob ze rau peb. Fossil slabs nyob rau hauv chav dej ntawm Guiyang tshav dav hlau yog tsim nyob rau hauv Yunnan, Guizhou thiab Sichuan, thiab ntau ntawm lawv yog siv nyob rau hauv lub tsev cov ntaub ntawv kev lag luam. Ua kom zoo nkauj marble slab.
1. Cov pob txha
Fossils yog cov seem, relics, los yog relics ntawm ancient creatures nyob rau hauv lub ancient strata. Nyob rau hauv layman cov ntsiab lus, fossils yog pob zeb ua los ntawm cov seem los yog relics ntawm creatures nyob rau yav tas los deb.
Nyob rau hauv lub hnub nyoog geological ntev, suav tsis txheeb creatures tau nyob hauv lub ntiaj teb. Ntau qhov seem lossis ib qho ntawm lub neej tom qab kev tuag ntawm cov tsiaj no raug faus los ntawm cov xuab zeb thaum lub sijhawm ntawd.
Nyob rau hauv lub xyoo tom ntej, cov organic teeb meem nyob rau hauv cov seem ntawm cov kab mob no decomposed thiab tag, thiab cov tawv nqaij xws li lub plhaub, cov pob txha, ceg thiab nplooj, ua ke nrog cov nyob ib puag ncig sediments, tau petrified thiab tig mus rau hauv pob zeb, tab sis lawv cov qub. cov duab thiab cov qauv (Txawm tias qee qhov hloov maj mam sab hauv) tseem khaws cia; zoo sib xws, cov kab uas tshuav los ntawm cov tsiaj muaj sia kuj tuaj yeem khaws cia li no.
Peb xa mus rau cov fossilized biological seem thiab relics collectively li fossils. Fossils muaj xws li trilobite fossils, cog fossils, plhaub fossils, hneev taw fossils, dinosaur fossils, ntses fossils, thiab lwm yam.
Tsiaj fossils hauv Suav dub marble-Amen kaum pob zeb
Fossils feem ntau khaws cia rau hauv cov pob zeb sedimentary, yog li qee cov marbles nrog cov metamorphism kuj tuaj yeem pom. Tsis muaj pob txha pob txha hauv granite siv rau paving hauv nroog, tab sis yog tias koj muaj hmoo txaus, koj tuaj yeem nrhiav cov pob zeb hauv av xws li cov muaju hauv nws.
Prehistoric crocodile fossils ntawm marble slab
Ntau qhov zoo nkauj marbles los ntawm Egypt muaj cov pob txha hu ua "foraminifers".
Foraminifera yog ib tug loj-celled tsiaj, thiab tej zaum nws yuav yog ib tug loj tshaj plaws-celled tsiaj nyob rau hauv lub ntiaj teb no. Nws tuaj yeem pom tau yooj yim los ntawm qhov muag liab qab yam tsis muaj lub tshuab tsom, thiab qee qhov tuaj yeem loj hlob mus txog 2 cm! Cov tsiaj no tau tshwm sim hauv dej hiav txwv ntau dua 500 lab xyoo dhau los, thiab muaj ntau hom.
Txawm li cas los xij, cov khoom siv marble zoo heev yog nkig, thiab txawm tias nws pheej yig heev, nws tsis ruaj khov li cov khoom siv hauv pem teb.
Keeb kwm: Morocco
Hnub tim: lig Silurian 420 lab xyoo dhau los
Fossils: Nautilus fossils, lub kaum pob zeb (txoj cai-angled nautilus) pob txha, thiab lwm yam.
Cov roj ntsha dub limestone muaj ntau cov pob txha ntawm cov tsiaj hauv hiav txwv. Nws los ntawm Lesser Atlas Toj siab hauv Morocco thiab hnub rov qab mus rau Silurian lig 420 lab xyoo dhau los.
Feem ntau ntawm cov tsiaj khaws cia yog hornstones. Lawv tsis yog gastropod conch, tab sis yog ze ze rau "cov pob txha nyob" nautilus uas tseem muaj nyob hauv dej hiav txwv. Lawv kuj yog cephalopods nrog octopuses thiab squids.
Tom qab 400 lab xyoo ntawm kev faus thiab mineralization, lub plhaub ntawm cov hornstones tau ua dawb thiab ci, ua rau muaj zog dub-thiab-dawb sib piv nrog cov pob zeb tsaus nti. Ntxiv nrog rau hornstones, muaj curled kauv ammonites thiab crinoid fossils. Ntau yam tsiaj ua ke tsim lub ntiaj teb no "ntub qab dej".
