| 11. | The mostly postglacial Lake unit includes glassy rhyolite, which is poor in crystals.
|
| 12. | The postglacial rocks have very similar element compositions.
|
| 13. | Thus, the observations of postglacial rebound provide a natural experiment to measure mantle rheology.
|
| 14. | All geological formations are quite recent, dating from the Ice Age and postglacial times.
|
| 15. | Conditions favourable for human settlement occurred in the present Wyrzysk Region in the postglacial period.
|
| 16. | Gulf of Utica was formed during the postglacial transgression about 6, 000 years ago.
|
| 17. | Populations in Europe are genetically relatively homogeneous, perhaps reflecting postglacial colonization representing a single lineage.
|
| 18. | The volcanic system consists of lava fields, postglacial basaltic crater rows, and small shield volcanoes.
|
| 19. | Similarly extensive spreads of peat have developed across parts of the plateau surface in the postglacial period.
|
| 20. | Several small shield volcanoes, and postglacial lapilli cones and lava flows have been reported in this area.
