Title: Paleomagnetic Correlation: ABSTRACT

Author(s): Neil D. Opdyke

Article Type: Meeting abstract


There are two ways in which paleomagnetic results can be used to correlate rock formations with each other. The first is achieved by using an established paleomagnetic polar-wander curve and matching new results to this curve. The second is by determining a reversal sequence and using this to correlate sedimentary strata.

In the past, both methods have been successful, the first in correlating older rocks and the second in dealing with rocks of Pliocene and Pleistocene ages. The reversal method is discussed in respect to its recent successful application to marine sediments of Miocene or younger age. The possible extension of this technique to older rocks is investigated and a recent successful application of magnetic reversal stratigraphy in rocks of Triassic age is outlined. It is reasonable to predict that reversal sequences will be of most value in older rocks where independent faunal or mineralogical control is present. It should also be of value as a well-logging tool for correlations within individual sedimentary basins.
