One is the detailed discussion of the changing ecology of the marine world in the Proterozoic and early Phanerozoic
For example, if all Phanerozoic
volcanic arcs are palaeo-geographically delineated and reconstructed to their present-day locations, then some of them (from different geological time periods) will overlap in areas where subduction was pro longed, or where subduction-related magmatism repeatedly affected the same area of continental crust.
Characteristics of dynamic, filtration, hydrochemical and thermal parameters of the upper part of Phanerozoic
in the environs of KDGP generalized based on abundant geological survey, water and oil prospecting, and special investigation data (Dortman 1992; Kepezinskas et al.
Insect origination and extinction in the Phanerozoic
Strong coupling of predation intensity and diversity in the phanerozoic
86]Sr for the Phanerozoic
has been analyzed in numerous studies (e.
The tables typically focus on Phanerozoic
time and identify the approximate dates of geological periods, but geological time before the Paleozoic era is usually identified as "Precambrian.
The rarity of syneresis cracks in Phanerozoic
marine rocks is a consequence of greater content of organic matter in the sediment and organic binding of clay flocks in the water (Pratt 1988).
Taking into account that at least five outstanding mass extinction events were registered during the past 600 million years it seems logical to assume that probably a higher number of still undocumented mass extinction events occurred during the about 6 times more extended pre Phanerozoic
The First Baltic Stratigraphical Conference in Vilnius in 1976 adopted the primary version of the unified stratigraphical classification with correlation charts for the entire Phanerozoic
represented in the Baltic area.
Such traces are commonly reported from marine paleoenvironments throughout the Phanerozoic
