Notes:
* Direct results on C and O will be available from the analysis of alpha spectra at a later date.
** O is calculated from oxide stoichiometry, assuming S in the form of SO3 and Fe in the form of FeO.
*** Values for K and Mn are upper limits; more accurate numbers will be available after further analysis.
Analysis based on X-ray data.
Values for potassium and manganese are upper limits; more accurate numbers will be available after further analysis.
Minor elements such as phosphorus, chlorine and chromium are omitted from this table.
