Palynological analysis of Lower Cretaceous (Berriasian-Barremian) sections from North Siberia allows definition of detailed dinocyst and sporepollen zonations, which are calibrated against the establi...
Lower Cretaceous lithostratigraphy across a regional subaerial unconformity in Spitsbergen:the Rurikfjellet and Helvetiafjellet formations
Lower Cretaceous lithostratigraphy regional subaerial unconformity Rurikfjellet and Helvetiafjellet formations
2009/12/2
During development of the Lower Cretaceous succession in the Spitsbergen domain of the epicontinental Boreal Basin, a fall in relative sea-level caused a major subaerial unconformity to form. This unc...
