Miocene 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 ...

Steens Basalts: North Mickey Section
The section at North Mickey (42.8?N, 118.3?) is 25 km east of Steens Mountain at the north end of the Mickey Basin (Figure 4). The section is on a downward dropped block of Steens Basalt as mapped by Hook (1981) and ?correlation is established on the basis of a paleomagnetic reversal observe ...
