eustacy
基本解释
- n.海面升降；海面变化
英汉例句
- The formation of auriferous stratawas controlled by volcanism and eustacy.
火山作用和海平面变化对含金地层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.
这可以从沉积砂堤与含贝壳砂堤的分布看出，它们都曾是不同时期海岸位置的所在。 - 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.
层序3、层序4和层序5的底界面是在构造作用稳定、全球海平面下降背景之上由相对海平面次一级旋回变化形成的，是古气候变化、沉积物供给及构造沉降共同作用的结果。 - 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.
首次将河谷深切和深厚堆积事件与全球气候变化、海平面升降运动、地壳运动等有机地联系起来，并提出冰期、间冰期全球海平面大幅度升降，是导致河流深切成谷并形成深厚堆积的主要原因的新观点。 - Sea level eustacy
