Pansi pa Dziko Lapansi wapangidwa ndi zigawo ongokhala mafunde kotenga wa nthawi Carboniferous. miyala lolemererapo kugona mu zigawo m'munsi ndi chapamwamba amene timapemphera miyala carboxylic. Izi zikusonyeza kuti m'mbuyomu dera limeneli linali seismically yogwira, koma pakadali ntchito iyi chazirala. Ngakhale, malinga ndi zotsatira kafukufuku m'dera la pachilumbachi Gaspe nthawi anamva mkulu kotenga yoweyula liwiro (za 8.5 km / s).

Muyenera ndithudi kukaona malo awa, chifukwa ulendo adzatsala wosaiwalika wa moyo. Palibe alendo sadzamlekerera kuti anali pano.
