Nature research paper: Hadean isotopic fractionation of xenon retained in deep silicates
we would had measured if the sample fragment had been directly melted. For S1–11d , we observe variations ofby a roughly 2-fold factor along the heating ramp. For this same sample, an unfractionated component was evidenced for the lowest laser voltage, but represent a marginal part . Since for similar heating power, ~45% of the total Xe of S1–19b was released, this low. at the sample melting point, for S1–19b and S1–11d respective 0.54 ±0.12 ‰/amu and 0.61 ±0.
11 ‰/amu fractionations were measured, which points towards a Xe component with some fractionated Xe, but still with an unfractionated component lowering the overall measured.
