According to mass balanced palaeogeographic reconstructions proposed by Hay et al (1989), palaeogeography, palaeotopography and palaeobathymetry of a closed erosional depositional system can be reconstructed by restoring sedimentary masses to elevated surfaces in a drainage basin based on the inverse of present erosion equations and adjusting for isostasy, sea l.

5) paleogeomorphy
古地貌
1.
The paleogeomorphy plays an important role in controlling sequence forming and growing as well as reservoir distribution,while the restoration of paleogeomorphy can help recognize reservoir growth and its distribution characters,judge the paleogeomorphic environments,the distribution of paleo-organisms and the characteristics of structural evolution.
古地貌对层序的形成与发育以及储层的分布起着重要的控制作用,古地貌的恢复可以有助于识别储层发育与分布特点、判断古地理环境、古生物分布以及构造演化特征等。
2.

补充资料：古地貌
| 古地貌 relic landform 基本形态与现代地貌塑造过程完全脱离的、与现代大地构造条件不相适应的地貌单元。古地貌往往不易被完整地保留下来，尤其是在构造隆起的剥蚀区。在抬升地区可出露地表，如山顶的准平原、风口的古河谷等；在沉降地区被埋藏于现今地貌面之下，如古河道、古潜山、古沙丘等。根据古地貌遗迹可寻找矿产资源，如石油、天然气、砂矿、地下水等，亦可推测形成古地貌时的自然环境，对农业生产具有重要意义。 |
