Late Cretaceous Paleogeographic Map
The global paleogeographic reconstruction for the early Turonian has been prepared by Balukhovsky et al. (2004). This map was constructed using the techniques involved in producing the Paleozoic and Mesozoic-Cenozoic Atlases of Lithological-Paleogeographic Maps of the World (Ronov et al. ...

Paleocene Paleogeographic Map
The global paleogeographic reconstruction for the Paleocene has been prepared by Balukhovsky et al. (2004). This map was constructed using the techniques involved in producing the Paleozoic and Mesozoic-Cenozoic Atlases of Lithological-Paleogeographic Maps of the World (Ronov et al., 1984 ...

Direction of Changing Magnetic Poles based on Basalt Samples in Japan
The figure shows the varying directions the magnetic pole has taken based on basalt samples in Japan. The samples span over a time period that begins in the early Quaternary and ends in the Tertiary. Using the locations on the graph and their respective time periods, it can be seen that th ...

Paleolatitude Data From Ocean Drilling Project Leg 197
This diagram show the age and location of sediments taken from various seamounts in the Hawaiian-Emperor Chain during leg 197 of an Ocean Drilling Project (ODP) expedition. The age is determined by paleomagnetic anomalies. It is shown that there were periods of simultaneous eruptions occurrin ...

Paleolatitude Values For Seamounts
This image shows the average paleolatitude value for Detroit Seamount derived from magnetic anomalies within the basaltic rock. Several trajectories are also shows which represent different combinations of plate and hotspot motion. The red line is a least squares fit to the data.

Age of Hawaiian Islands and Outer Seamounts graph
This graph represents the data from the Age of Hawaiian Islands and Outer Seamounts data set. It exemplifies fluctuations in the somewhat linear relationship of distance from Kilauea and age that are possibly contributed t ...
