Phanerozoic paleoenvironment and paleolithofacies maps. Cenozoic
(Wydawnictwa AGH, 2009) Golonka, Jan
The paper presents the detailed plate tectonic, paleogeographic, paleoenvironment and plaeolithofacies maps for seven Cenozoic time intervals. Thirty five maps, generated using PLATES and PALEOMAP programs, contain information about plate tectonics, paleoenvironment, and paleolithofacies during Paleocene, Eocene, Oligocene, Miocene and Pliocene, time slices. The spatial reconstruction of basin architectures during their origin, expansion, closure and inversion as well as the dynamic of intrabasinal ridges were obtained by palinspastic modeling. This modeling utilized paleomagnetic data and stratigraphic-facies analysis of basins and ridges. Information contained within global and regional papers were selected and posted on the maps. The detailed paleoenvironment and plaeolithofacies zones were distinguished within the basins. The paleogeographic maps illustrate the geodynamic evolution of Earth from Late Cretaceous to Neogene, spreading and origin of new oceans, oceans closing, collisions, continents accretion and origin of new supercontinents.
Phanerozoic paleoenvironment and paleolithofacies maps. Early Paleozoic
(Wydawnictwa AGH, 2009) Golonka, Jan
The paper presents the detailed plate tectonic, paleogeographic, paleoenvironment and plaeolithofacies maps for eight Early Paleozoic time intervals. Forty maps, generated using PLATES and PALEOMAP programs, contain information about plate tectonics, paleoenvironment, and plaeolithofacies during Cambrian, Ordovician and Silurian. Disintegration of supercontinent Pannotia and origin of Gondwana, Laurentia and Baltica occur during Early Cambrian. Oceans spreading continued during Late Cambrian and Early Ordovician, vast platform flooded by shallow seas existed on the continents. The plate tectonic reorganization happened during Middle Ordovician. Silurian was a time of Caledonian orogeny, closing of Early Paleozoic oceans and origin of supercontinent Laurussia as a result of Laurentia and Baltica collision. Information contained within global and regional papers were posted on the maps and the detailed paleoenvironment and plaeolithofacies zones were distinguished within the platforms, basins and ridges.
