Background: Use of descriptive logs for comparative visual analysis of sediment from cores and borings is rarely as satisfactory as first hand study of the actual material. This is true because subtle visual properties which cannot be fully described are often important in showing relationships. Where large numbers of samples are being analyzed, comparison of the sediments in their original containers is cumbersome and requires considerable space for layout. In addition, the analyst, being unable to scan more than a few samples at a time, is less efficient in perceiving relationships. A useful expedient for making preliminary comparative analysis of a large number of samples is to glue small representative subsamples on illustration board cards work with the whole sample and for more sophisticated forms of analysis. However, carded samples are very useful during preliminary analysis and correlation, and as a basis for selection of representative samples for more detailed study.
