常見例句The formation of auriferous stratawas controlled by volcanism and eustacy. 火山作用和海平面變化對含金地層的形成起到了控制作用。To sum up, it arose from eustacy, transportation of sediment and lithosphere uplift relatively of the region due to the neo-tectonic movement. 這可以從沉積砂堤與含貝殼砂堤的分布看出,它們都曾是不同時期海岸位置的所在。The bottom boundary of sequence 3, sequence 4 and sequence 5 results from integrated effect of change of climate, sediment source and tectonic activity under falling global eustacy. 層序3、層序4和層序5的底界面是在構造作用穩(wěn)定、全球海平面下降背景之上由相對海平面次一級旋回變化形成的,是古氣候變化、沉積物供給及構造沉降共同作用的結果。Deeply cut valley and deep accumulation events, global climate change, sea-level eustacy motion and crustal movement organically linked up are reported for the first time in this paper. 首次將河谷深切和深厚堆積事件與全球氣候變化、海平面升降運動、地殼運動等有機地聯(lián)系起來,并提出冰期、間冰期全球海平面大幅度升降,是導致河流深切成谷并形成深厚堆積的主要原因的新觀點。Sea level eustacy 海平面升降 返回 eustacy
