Mitengo ikuluikulu ndi mitundu yatsopano pansi pa dzenje ndi kuya kwa 192 metres
Asayansi aku China apeza mitundu yosadziwika ya nyama ndi zomera pansi pa dzenje m'chigawo cha Guangxi, m'chigawo cha Lue kum'mwera kwa China, nyuzipepala ya The Guardian inanena posachedwapa.
Pofufuza mapanga a 30 m'derali, akatswiri a speleologists adapeza phompho lalikulu kwambiri m'deralo - mapangidwe a karst, dzenje lokhala ndi makoma pafupifupi ofukula - kupitirira mamita 300 m'litali, mamita 150 m'lifupi ndi mamita 192 kuya kwake.
Gulu la Guangxi 702 Honging Cave Expedition Team lapeza chinthucho pogwiritsa ntchito zithunzi za satellite. Phompho lili pakhomo la mtsinje wa Fugui mobisa ku Lue County. Pa Meyi 2, Zhang Yuanhai, mainjiniya wamkulu ku Institute of Karst Geology ya Chinese Geological Survey, adapita pamalowa kuti akatsimikizire.
Pa Meyi 6, gulu la anthu 8 laulendo wasayansi, wopangidwa ndi ofufuza ochokera ku Institute of Karst Geology ya Chinese Geological Survey ndi Gulu la Guangxi 702 Cave Expedition Team, adanyamuka kupita kuphompho.
Gulu la ulendo wa sayansi linatsika mwala kwa mamita 100 ndipo pambuyo pa maola angapo otsika potsirizira pake linafika pamalo otsika kwambiri pansi pa phompho. Kumeneko imakwawa pang’onopang’ono m’munsi, ikudutsa m’nkhalango yowirira ya pansi pa nthaka yopotana ndi mipesa.
"Mitengo yakale yomwe imakula molunjika pamwamba pa phompho ndi pafupifupi mamita 40 kutalika, ndipo zomera zamthunzi wandiweyani zimatsala pang'ono kuphimba mapewa athu," anatero Chen Lixin, wamkulu wa Gulu la Guangxi 702 Cave Expedition Team.
“Sindingadabwe kumva kuti pali zamoyo zomwe zimapezeka m’mapanga amenewa zomwe sizinafotokozedwepo kapena kufotokozedwa ndi sayansi,” Lisin anauza nyuzipepala ya The Guardian.
“Mafuko aakulu atatu ajambulidwa m’makoma a phompho, amene amakhulupirira kuti ndiwo mabwinja a mapanga m’magawo oyambirira a kusinthika kwa mapangidwe a karst. Pansi pa phompho pali dongosolo la nkhalango ya namwali yosungidwa bwino, yomwe imabisala miyala yambiri yowonongeka. "Kaya uwu uli umboni wa chisinthiko kachiwiri kapena ayi, ulinso ndi chilengedwe chapadera pambuyo pa kupangidwa kwake komwe kuli ndi phindu lalikulu la sayansi ndi sayansi," anatero Zhang Yuanhai, injiniya wamkulu pa Institute of Karst Geology of the Chinese Geological Survey.
Kuchokera kumalingaliro a geological, phompho ndi phompho lalikulu la karst lomwe lili ndi mawonekedwe apadera komanso mawonekedwe achilengedwe, monga ma voliyumu akulu, makoma amiyala otsetsereka komanso mikombero yozama yowoneka bwino yowoneka ngati migolo kapena migolo. Phompho nthawi zambiri limakula m'matanthwe osungunuka a makulidwe akulu ndi madzi akuya, otsogolera mobisa kapena kumtunda, ndi m'lifupi mwake ndi kuya kwa mita 100, ndipo pansi nthawi zambiri amalumikizidwa ndi mitsinje yapansi panthaka.
Leye County ndi ya dera la karst kumwera kwa China. Awa ndi malo a gulu lalikulu kwambiri padziko lonse lapansi la anthu osambira, malowa amadziwika kuti "World Museum of Divers". Pakadali pano, chiwerengero cha osambira m'chigawo cha Lue chakwera kufika pa 30.
Zolosera za Lisin za zamoyo zatsopano zikuyenera kukwaniritsidwa, chifukwa malo akutali padziko lonse lapansi adapanga kale zomera ndi zinyama zochititsa chidwi, zapadera zomwe zimagwirizana ndi chilengedwe chawo. Zilumba za Galapagos mwina ndi chitsanzo chodziwika bwino, pali mitundu ingapo yachilengedwe yomwe sipezeka kwina kulikonse.

Chidziwitso: Phompholo linapanga bwanji?
Mapangidwe a sinki ayenera kukumana ndi zinthu zosiyanasiyana panthawi imodzi.
Chofunika kwambiri ndi mawonekedwe a miyala. Choyamba, makulidwe a laimu wosanjikiza ayenera kukhala okwanira kupereka malo okwanira kupanga phompho. Chachiwiri, makulidwe a vadose zone (mwala wosanjikiza wokhala ndi mpweya) uyenera kukhala waukulu mokwanira. Chachitatu, thanthwelo liyenera kukhala lofanana ndi dziko lapansi.
Chinthu chachiwiri ndi hydrological mikhalidwe. Choyamba, madzi a mtsinje wapansi panthaka ayenera kukhala akuya. Chachiwiri, mvula iyenera kukhala yayikulu mokwanira, ndipo kuyenda ndi mphamvu za mtsinje wapansi panthaka ziyenera kukhala zazikulu zokwanira kuti zichotse miyala yomwe yagwa. Kuphatikiza apo, mpumulo uyenera kukhala woyenera kugwa kwa zigawo za miyala.
Malingana ndi mtundu wa genesis, sinkholes akhoza kugawidwa mu mitundu iwiri - mwa kugwa kapena kukokoloka. Mapangidwe a phompho lakugwa amagawidwa m'magawo atatu: mtsinje wapansi panthaka, holo yowonongeka ndikutsegula mabowo padenga. Kukokoloka kwa mtundu wa sinkhole kumapangidwa ndi kukokoloka kosalekeza ndi kufalikira kwa madzi a pamwamba pa madzi ndi kuzama kwa kupambana kwa miyala ya carbonate.
Dzina la kuphompho karst mapangidwe amachokera ku Croatian ndi Slovenian. Amachokera ku liwu la Proto-Slavic "nora", kutanthauza dzenje, dzenje, phompho.
Malo angapo ku Southeast Europe (Croatia, Czech Republic, Hungary, Romania, Montenegro, Slovenia) amatchedwa Ponor chifukwa cha kutsegulidwa kwa karst. Ku Bulgaria ili ndi phiri la Ponor pafupi ndi Lakatnik.
Chithunzi: Ofufuza paphanga apeza phompho ku Leye County. Ndi mamita 306 m’litali, mamita 150 m’lifupi ndi mamita 192 kuya kwake. Ngongole: news.hsw.cn
