洋脊中軸裂穀是板塊的創(chuàng)生邊界，是與地球內(nèi)部聯(lián)系最緊密的地表區(qū)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(duì)研究區(qū)中、晚石炭世區(qū)域古搆造環(huán)境的認(rèn)識(shí)，目前存在有限洋盆、裂陷槽、裂穀、島弧之爭(zhēng)。
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(gè)發(fā)育不完全的沉積盆地尚未發(fā)展成爲(wèi)大洋型盆地就衰亡了。
