You drilled the site below and found the pattern of normal and reversed polarity

Question

You drilled the site below and found the pattern of normal and reversed polarity based on paleomagnetic inclination. Using table 4 in Lisiecki and Raymo 2005, what are the ages of the reversal boundaries observed in the figure below? What is the sedimentation rate implied by those ages and how does the sedimentation rate change with time? What isotope stage would you expect to find at each polarity transition? What are uncertainties might you imagine from deriving a chronology by this method?

Figure 2) table 4 in Lisiecki and Raymo 2005, needed to find the reversals.

PLEASE answer all parts of the above questions, thank you!

Explanation / Answer

There are total three reversal phases within the given geological time span which are listed below:

1. Between 6H and 18H. This overall reverse phase of earth's magnetism contains short livved normal polarity also which ar at 8-9H and 12H and 13H

2. The next reversal is at 17H to 26H.

The rates of sedimentation in these periods are 10m per H and 7.14m per H

The rates of sedimentation present in the given succession, is higher in case of the reverse polarity and lower i case of the normal polarity.

U1314B is suitable for the studies of the polarity transition.
