Xyoo 1969, cov neeg ua haujlwm tsim kho hauv Oklahoma, Tebchaws Asmeskas, tau tshawb pom cov qauv coj txawv txawv uas zoo li cov neeg tsim thiab, raws li ntau tus kws sau ntawv, muaj peev xwm rov sau dua tsis yog keeb kwm ntawm Tebchaws Meskas nkaus xwb tab sis kuj yog keeb kwm ntawm tag nrho lub ntiaj teb.
Cov qauv no, uas zoo li lub pob zeb mosaic hauv pem teb, tau pom nyob rau hauv ib txheej uas cov kws tshaj lij ntseeg tias hnub rov qab 200 txhiab xyoo. Nyob rau tib lub sijhawm, nws yog dav xav tias cov tib neeg ntxov tshaj plaws tuaj txog hauv North America tsuas yog 22-19 txhiab xyoo dhau los.
Tsis ntev tom qab nws tshawb pom, ib tsab xov xwm hais txog qhov kev pom zoo tshaj plaws no tau luam tawm hauv cov ntawv xov xwm "Tus Oklahoman, " ua rau muaj kev sib cav hnyav ntawm cov kws tshaj lij thiab cov neeg nyeem txhua hnub. Zaj dab neeg kuj suav nrog peb daim duab dub thiab dawb ntawm no "mosaic," uas tseem yog tib cov duab tseem muaj sia nyob ntawm cov khoom no.
Nov yog yam uas tau sau nyob rau hauv tsab xov xwm:
"Lub Rau Hli 27, 1969, cov neeg ua haujlwm txiav los ntawm lub pob zeb nyob ntawm Broadway Extension ntawm 122nd Street, ntawm Edmond thiab Oklahoma City, ua rau muaj kev cuam tshuam rau qhov pom tias muaj kev sib cav ntau ntawm cov kws tshaj lij. …
Kuv paub tseeb tias nws yog tib neeg tsim vim hais tias cov pob zeb tau teeb tsa hauv cov kab sib txuas zoo kawg nkaus uas cuam tshuam los ua lub pob zeb diamond, txhua qhov taw qhia sab hnub tuaj, "said Durwood Pate, tus kws tshawb fawb hauv Oklahoma City uas tau kawm txog qhov teeb meem thiab qhov chaw zoo.
Peb kuj pom lub qhov rau tus ncej (tus ncej) uas zoo kawg nkaus tiaj tus. Sab saum toj ntawm cov pob zeb yog du heev, thiab yog tias koj khaws ib qho ntawm lawv, koj yuav pom ib yam dab tsi uas qhia tias hnav khaub ncaws saum npoo. Txhua yam yog qhov chaw zoo dhau los ua ib qho kev tsim ntuj tsim. "
Dr. Robert Bell, tus kws tshawb fawb keeb kwm yav dhau los ntawm University of Oklahoma, tsis pom zoo, thov tias qhov kev tshawb pom yog kev tsim ntuj tsim. Dr. Bell tau hais tias nws tsis pom qhov kos npe ntawm tus neeg ua haujlwm. Pate, ntawm qhov tod tes, nrhiav pom ib yam dab tsi zoo li grout - cov kua dej ntom ntom siv los sau cov khoob hauv cov tsev - nruab nrab ntawm txhua lub pob zeb.
Tus qauv, pom kwv yees li 90 centimeters hauv qab lub ntiaj teb saum npoo av, zoo li muaj ntau txhiab square feet, raws li Delbert Smith, geologist, thiab tus thawj tswj hwm ntawm Oklahoma Seismograph Company, thiab yav tas los tus thawj tswj hwm ntawm Oklahoma City Geophysical Society. “Tsis muaj qhov tsis ntseeg txog nws. Nws tau hais meej meej rau ntawd, tab sis kuv tsis paub tias leej twg tuaj yeem ua tau, " nws hais rau cov neeg sau xov xwm.
Geologysts Delbert Smith thiab Durwood Pate tau mus rau qhov chaw los tshuaj xyuas qhov tsim thiab sau cov qauv, raws li cov ntawv xov xwm. "Kuv ntseeg tias qhov no tsis yog lub ntiaj teb tsim, tab sis ib yam dab tsi tsim los ntawm tib neeg txhais tes," Smith hais tom qab.
Ob hnub tom qab, lub Rau Hli 29, 1969, lwm tsab xov xwm hais txog qhov kev tshawb pom no tau tshwm sim hauv cov ntawv xov xwm “Tulsa World”. Muaj Delbert Smith cov lus tau muab ntau dua qhov tseeb thiab kev sib tham ntawm cov khoom tau nrov rau thawj zaug:
"Tsis muaj qhov tsis ntseeg txog qhov ntawd. Nws tau tshwj xeeb ntsia los ntawm ib tug neeg, tab sis kuv tsis paub tias leej twg ua nws. "
“Lwm qhov kev paub tsis meej yog cuam tshuam nrog kev sib tham. Muaj cov kev xav sib txawv hais txog geology koom nrog, tab sis qhov tseeb tshaj plaws kwv yees ntawm lub hnub nyoog ntawm cov vuas no yog 200 txhiab xyoo. "
Kev tshawb nrhiav txuas ntxiv mus. Qhov nrhiav tau ntawm qhov thib ob hauv qhov "Mosaic" tau tshaj tawm hauv Oklahoman thaum Lub Xya Hli 1, 1969. Raws li cov txiaj ntsig ntawm kev ntsuas, muaj qhov deb ntawm tsib meters ntawm ob lub qhov. Raws li Pate, lub pob zeb siv los tsim cov mosaic yog kev sib xyaw ntawm Permian limestone thiab quartz nplej.
Thaum Lub Xya Hli 3, Cov ntawv xov xwm Oklahoman txuas ntxiv nws qhov kev tshawb pom, taw qhia tias raws li cov lus ceeb toom los ntawm archaeologists, ib qho "Ancient pob zeb rauj" kuj pom ntawm qhov chaw.
"Qhov paub tsis meej ntawm dolomite limestone tsim nyob nruab nrab ntawm Oklahoma City thiab Edmond tau ua rau hnub Wednesday ntau dua los ntawm kev tshawb pom cov khoom zoo li rauj ntawm qhov chaw."
Geologists uas tau them nyiaj rau qhov txawv txav tau pom tias nws nyuaj rau piav qhia txog keeb kwm ntawm kev tsim lossis khoom cuav. John M. Ware, tus kws tshawb fawb hauv Oklahoma City, hais tias: "Nws tsuas yog tsis tuaj yeem piav qhia txog geology - peb xav tau ib tus kws tshawb fawb keeb kwm yav dhau los los muab lub tswv yim kawg. Txawm li cas los xij, nws lub hnub nyoog thiab keeb kwm yuav nyob twj ywm tsis paub yog tias tus kws tshawb fawb qub txeeg qub tes tsis tuaj yeem yaum nws los ua qhov project sai sai. "
"Tsis pub dhau 20 hnub, cov neeg tsim khoom yuav txuas ntxiv lawv txoj haujlwm ntawm kev khawb ntawm thaj chaw txhawm rau txhawm rau pib tsim lub tsev khaws khoom noj khoom haus. Lwm qhov ntxim nyiam ntawm lub pob zeb yog tias nws muaj cov pob zeb hauv hiav txwv, qhia tias nws yog ib qho dej hiav txwv hauv av. "
Pate ntxiv tias "Kev tsim 100-by-60-foot yog nrawm dhau los ua ib qho chaw ncig xyuas."
“Cov neeg tuaj yeem tuaj rau ntawd thiab rub tawm cov pob zeb. Peb yuav tsum khaws nws mus txog thaum ib yam dab tsi ua tiav los txiav txim nws qhov keeb kwm. "
Hmoov tsis zoo, yuav luag me ntsis cov ntaub ntawv ntxiv txog qhov kev tshawb pom txawv txawv no tau tshaj tawm hauv Oklahoma xov xwm tom qab ntawd, thiab qhov tshwm sim tiag tiag rau nws tsis paub meej txog niaj hnub no.
