From: Extreme lithium isotopic fractionation in three zircon standards (Plešovice, Qinghu and Temora)
(a) Trace outlines on the CL image of Plešovice-R to show the position of the Li isotopic and [Li] measurements by SIMS. (b) The ion image of the variation of Li and Y content (bright colors = higher concentration). (c) δ7Li vs relative distance to the rim. (d) [Li] vs relative distance to the rim. Uncertainty of standard analysis (2SD) has been shown in the plots while 2SE of individual analyses is smaller than 2SD. Typical analytical uncertainty of δ7Li is ∼2‰ for the 20 μm pits, ~2.5‰ for the 10 μm pits and ∼5‰ for 5 μm pits (2 SD). Distance to rim is calculated by the X-Y position of the analytical spot to the nearest rim.
