Fig. 2: Comparison of the number of grains counted in a sieve analysis

The distribution of ice rafted debris (IRD) is an important parameter in glaciomarine sediments. A simple method is presented allowing the determination of the IRD-content by counting the gravel fraction of the X-radiographs which are generally taken during sarnpling. In comparison with sieve analys...

Description
Summary:The distribution of ice rafted debris (IRD) is an important parameter in glaciomarine sediments. A simple method is presented allowing the determination of the IRD-content by counting the gravel fraction of the X-radiographs which are generally taken during sarnpling. In comparison with sieve analyses corresponding values are obtained by both methods. However, more information can be made available in a shorter time by this method.
