Rapid cooling of planetesimal core-mantle McKibbin et al. Rapid cooling of planetesimal core-mantle reaction zones from Mn-Cr isotopes in pallasites Figure 1 LA-ICP-MS trace element concentrations traverses in olivine for (a) Brenham (left panels) and (b) Brahin (right panels). Traverses were conducted from core to rim; concentrations are in parts per million by weight (ppm) and horizontal axes represent distances from olivine rims (μm). Data are represented by grey points and traverse averages are traced by solid lines. Vertical dashed lines (blue and green for Brenham and Brahin respectively) represent limit of SIMS spatial resolution (~30 μm) when analysing near olivine margins. LA-ICP-MS tracks from this study and ablation pits from previous work (McKibbin et al., 2013c).
