Amanena kuti anabweretsedwa kumphepete mwa milungu - izi ndi momwe anthu a ku New Zealand amafotokozera alendo oyenda chidwi, kumene kumakhala miyala ya Moeraki yodabwitsa. Zoonadi, palibe chinthu chomwe chingawasonkheze. Zoonadi iwo adalengedwa ndi chibadwa cha amayi?
Mbiri ya zochitika
Asayansi amakhulupirira kuti miyala iyi inayamba mu nyengo ya Cenozoic, nyengo ya Paleocene (zaka 66-56 miliyoni zapitazo). Zambiri mwa miyalayi zinakhazikitsidwa pa nyanja ndi pamtunda. Izi zimatsimikizira kuwerengedwa kwa mipira: ili ndi mayendedwe amtundu wa oxygen, magnesium, chitsulo, ndi carbon.
Zomwe mungazione ku New Zealand, choncho zili pamabwinja a Moeraki
Mphepete mwa miyala, yomwe ili bwino kwambiri, ili pamphepete mwa nyanja ya Koehoe, yomwe ili pakati pa Hempden ndi Moeraki. Amatchedwa mipira yamwalayi polemekeza mudzi wausodzi wa Moeraki.
N'zosangalatsa kuti pamtunda mungathe kukumana ndi nambala yaikulu (pafupifupi 100) yamwala. Mipira yodabwitsa imeneyi ili pambali mwa nyanja, kutalika kwa mamita 350. Mbali imakhala pamchenga, gawo - m'nyanja, zomwe zimakhalapo m'magazi.
Mzere uliwonse wa mwala uliwonse umasiyana wina ndi mzake: kuchokera 0,5 mamita mpaka 2.5 mamita. Mwachilendo, pamwamba pa zina zimakhala zosalala bwino, pamene zina zimaphimbidwa ndi ziphuphu zomwe zimawoneka ngati chipolopolo cha nyambo yamakedzana.
Ndithudi, kukongola uku kukukopa ndipo kumakopa kwambiri asayansi ambiri. Mwachitsanzo, miyala ikuluikulu inaphunzitsidwa mothandizidwa ndi makina osakaniza a electron, komanso X-rays. Zinawonetsedwa kuti zimakhala ndi matope ndi dothi, zogwirizana ndi calcite, komanso mchenga. Ponena za kuchuluka kwa kudzikuza, zikhoza kukhala zofooka, ndipo zina zimafika kunja. Pamwamba pa boulders ndi calcite.
Ndipo wasayansi woyamba yemwe anali ndi chidwi ndi chodabwitsa ichi cha New Zealand ndipo anakhala Volter Mantell. Kuyambira mu 1848, adawaphunzira mwatsatanetsatane, akugwirizanitsa nawo kafukufuku ambiri, chifukwa dziko lonse lapansi adaphunzira za mipira ya Moikaak. Mpaka pano, alendo pafupifupi 100,000 amafika ku gombeli chaka chilichonse kukawona miyala yodabwitsa.
Kodi mungapeze bwanji?
Tikufika ku Otago poyendetsa pagalimoto kapena pa basi 19, 21, 50 ndikupita ku Koehohe.
