^*Values are given as a weight percentage. Only values exceeding a 5% threshold are recorded in the table. The value of the element with the greatest percentage for each part of the core assembly is indicated in bold.

^@Presence of gallium (7%) may be a possible misidentification of Zn.

^#Presence of Antimony (12%) may be a possible misidentification of Sn.
