The reconstruction and analysis of palaeowater depths: a new approach and test of micropalaeontological approaches in the post-rift (cretaceous to quaternary) interval of the northern North Sea

摘要: This paper explores and tests a new ecelectic approach to micropalaeontological data which are used reconstruct palaeowater depths in the Norwegian North Sea period from Cretaceous Quaternary. These ideas evidence presented here promote greater understanding of palaeobathymetry basin evolution. account focuses particular upon Cenozoic sediments this region although has general applicability. Such information is important because palaeobathymetric variations palaeobasin shape essential for recognition tectonic phases, distribution source rocks. Palaeobathymetric curves with upper lower depth limits derived part statistical analyses were constructed present most likely through time region. The obtained investigations compared palaeobathyemtric that suggested by independent structural restorationms outcomes these two approaches shown be essentially similar implies soundness data. Both restoration results point following: shallowing Early Cretaceous; deepening middle Late Palaeogene; early Neogene, deppening late Neogene (Pliocene). Quaternary interval wells study illustrates complexity palaeoenvironmental record over time, some clearlt showing subsidence while others suggesting relative uplift. result impact ice movement multiple glaciations subsequent isostatic re-adjustments.
