Explanation / Answer

Hanawalt method. In this method, you make a list of the unknown peaks, that is, their values of d, in decreasing order of intensity. Then you look in the search manual in the section that contains the most intense peak. Within each section the minerals are listed in the order of decreasing d of the second most intense peak.
