Zaka zingapo zapitazo, ofufuza adazunguzika ndi zofukula zakale zomwe zidafukulidwa mozungulira Chigawo cha Qinghai pafupi ndi Phiri la Baigong pafupi ndi mzinda wa Delingha, kumwera chakumadzulo kwa China, ndipo chinsinsichi sichinadziwikebe mpaka pano, ndi umboni wokwanira wosonyeza zomwe akunenazo ndi akatswiri azakale zakuthambo. Mu 2002, ofufuza adadzidzimuka atapeza nyumba zingapo zapangidwe kazitsulo zokhala ngati mapaipi zophatikizidwa m'miyala yozungulira Phiri la Baigong, lomwe ndi White White Mountain.
Mapaipiwa adapezeka pafupi ndi Qadim Basin, yomwe ili m'munsi mwa mapiri a Himalaya. Nyengo yoipa yamderali yayipangitsa kukhala yopanda mbiri m'mbiri yonse ya anthu, ndipo pali umboni wochepa wokhazikika kwa anthu pano, ngakhale lero pomwe oweta okha amangodutsa pamalopo ndikusunthira msipu wachonde kumwera.
Chiyambi cha mapaipi awa a Baigong ndi omwe adawamanga akadali chinsinsi. Kupeza kofunikira kwambiri kunali kutulutsa ngati piramidi wokwera mita 50-60. Kutuluka uku kuzunguliridwa ndi makina okonzedwa bwino ngati mapaipi omwe amatsogolera ku Nyanja Toson Hu, nyanja yamchere yamchere pafupifupi 300 mita.
Kutuluka kumeneku kuli ndi zipata zitatu, ziwiri zomwe zidagwa, kusiya chachitatu chitsogoze kuphanga lokumbidwa lokhala ndi mapaipi olowa mkati mwanyumba zamkati ndi makoma. Kupeza kumeneku, komanso kutuluka kwa mapaipi, ndi ma payipi omwe amalumikiza ku Nyanja Toson Hu, ofufuza adazunguzika, makamaka popeza kutuluka kwake kuli pamtunda wamamita 300 kuchokera kunyanja yamadzi abwino.
Kodi nchifukwa ninji aliyense adasankha nyanja yamchere yamchere ndikupanga maukonde ovuta omwe amalumikiza ndi kuphulika? Kodi uwu unali malo akale ofufuzira? Kapena malo ena akale akuthambo kapena poyambira?
Pali ma saizi angapo omwe amagwiritsidwa ntchito pama payipi, okhala ndi mapaipi akulu mpaka 1.5 mita m'mimba mwake, ndi mapaipi ang'onoang'ono omwe amakhala mainchesi ochepa chabe. Mapaipi omwe amapanga makinawa amatchedwa Baigong Pipes ndipo amadziwika kuti Bai-Gongshan Iron Pipe.
M'maso mwa akatswiri ofukula zakale komanso akatswiri a mbiri yakale, mipope ya Baigong imagwirizana bwino ndikulongosola kwa buku lazinthu zakale zomwe zidapezeka kunja kwa malo (OOPART).
Beijing Institute of Geology idagwiritsa ntchito radiocarbon dating kuti iwonetse kuti mapaipi achitsulowa anali atasungunuka zaka 150,000 zapitazo. Ndipo ngati adapangidwa ndi anthu, mbiri monga tikudziwira iyenera kuyesedwanso.
Ofufuzawa adagwiritsa ntchito thermoluminescence kuti awone kutalika kwa mchere wa crystalline womwe udawunikiridwa ndi dzuwa kapena kutentha. Anthu amaganiza kuti akhala m'derali zaka 30,000 zapitazo. Ngakhale m'mbiri yodziwika m'derali, anthu okhawo omwe amakhala kumeneko anali osamukasamuka omwe moyo wawo sunasiye nyumba zoterezi.
Ngakhale ena ayesa kufotokoza mapaipi ngati zinthu zachilengedwe, Yang Ji, wofufuza ku "Chitukuko cha China cha Sayansi Yachikhalidwe," adanena "Xinhua" kuti piramidiyo mwina idapangidwa ndi anthu anzeru.
Zowonjezera zakumbuyo zakumbuyo zimatha kukhala ndi udindo, adatero, ndikuwonjeza kuti chiphunzitsochi ndi "Zomveka komanso zofunikira kuzifufuza ... koma njira za sayansi ziyenera kugwiritsidwa ntchito kuti zitsimikizire ngati zili zowona kapena ayi."
Lingaliro lina ndiloti lidamangidwa ndi mbiri yakale ya anthu (monga tafotokozera mu Silurian Hypothesis wolemba asayansi a NASA) pogwiritsa ntchito njira zomwe zidatayika kwa anthu omwe adatsata. Malinga ndi wamkulu wa dipatimenti yodziwitsa anthu zakomweko ku Delingha komweko, mapaipi adasanthulidwa ndi utsi wakomweko, ndipo 8% yokha yazinthuzo sizimadziwika kuchokera kuzinthu zina.
Zinthu zotsalazo zidapangidwa ndi ferric oxide, silicon dioxide, ndi calcium oxide. Kapangidwe ka silicon dioxide ndi calcium oxide ndi zotsatira za kulumikizana kwakukulu pakati pa chitsulo ndi mwala wamchenga wozungulira, zomwe zikuwonetsa kuti mapaipi ali ndi zaka masauzande. Injiniya Liu Shaolin, yemwe adawunika, adauza Xinhua kuti "Izi zapangitsa kuti tsambalo likhale losamvetsetseka."
Wofufuza za geology wochokera ku China Earthquake Administration dzina lake Zheng Jiandong adauza nyuzipepala yaboma “Anthu Tsiku ndi Tsiku” mu 2007 kuti mapaipi ena adapezeka kuti anali ndi nyukiliya kwambiri, zomwe zidawonjezera chidziwitso.
Mapaipi amathanso kukhala mizu ya mitengo, malinga ndi lingaliro lina. Asayansi adapeza chomera chotchedwa detritus komanso zomwe zimawoneka ngati mphete zamitengo pophunzira mapaipi, malinga ndi Xinmin Weekly mu 2003. Kupeza kumeneku kunalumikizidwa ndi lingaliro la geological kuti mizu yamitengo imatha kukhala ndi diagenesis (kusintha dothi kukhala thanthwe) ndi njira zina zomwe zimapangitsa kuti chitsulo chizisungika pansi pa kutentha ndi mankhwala.
Lipoti la a Xinmin Weekly pazomwe zimayambitsa mapaipi a Baigong lidayambiranso m'nkhaniyi, ndipo palibe kafukufuku amene akuphatikizamo ndemanga. Ponena za mapaipi a Baigong, palibe chidziwitso chotsimikizika chonena kuti chiphunzitsochi ndi cholimba.
