Co dalej z dewońską krzywą eustatyczną

IMPROVEMENTS SUGGESTED FOR THE DEVONIAN EUSTATIC CURVE Summary Results of the international symposium on Devonian eustasy in Moscow in July 1994, as well as ideas presented in several recent publications markedly confirmed an overall global control of major facies movements by Devonian sea-level fluctuations (Figs 1,2), as supposed by Johnson and co-authors in 1985 (and earlier by House). Refinement and new subdivision of their Euramerican eustatic cyclicity scheme are more and more necessary (Figs 2, 3) toward its standardization in the whole Devonian World. Data from Polish and East European epicontinental sequences are significant in this modification, as exemplified by early Frasnian (llb/c) deepening pulse. More and more numerous recognizable sea-level falls seem to be especially important to understanding of Devonian successions in terms of sequence stratigraphy. Such improved eustatic curve would be reliable chronostratigraphic framework for event interpretation of sedimentar...
