洋脊中軸裂穀是板塊的創生邊界，是與地球內部聯系最緊密的地表區域之一。
There are many disputations about the geological setting in Carboniferous of the Bogeda Mountain, such as small oceanic basin, aulacogen, rift or Island-Arc and so on.
對研究區中、晚石炭世區域古搆造環境的認識，目前存在有限洋盆、裂陷槽、裂穀、島弧之爭。
This sequence reflects the development of an incomplete depositional basin that started from extensional fracturing, went through a rift stage and failed before developing into an oceanic basin.
該序列反映了一個發育不完全的沉積盆地尚未發展成爲大洋型盆地就衰亡了。
