Table A.8

Average peak position shift summary by major bands of minerals.

mineral	band	1st irr.	deviation	2nd irr.	deviation	3rd irr.	deviation	avg. deviation after irr.
olivine	849.2	−11.33	6.5	2	12.8	1.8	5.7	8.3
olivine	887.8	4.4	3.6	−4	3.6	0.6	4.8	4
feldspar	1152.1	−1.58	20.4	2.16	19.9	−1.4	15.7	18.7
pyroxene	1047.2	−7.8	14.9	7	19.6	1.4	5.6	13.4
spinel	666.1	−3.22	5.9	0.11	1.9	3.4	2.9	3.6

Notes. Average peak position shifts, where minerals occur after all of the irradiations (spinel, pyroxene, feldspar, but not olivine because of less data). The standard deviation of peak shift is the difference from the average values of peak shift position.
