Extended Data Fig. 3: Metaigneous xenolith zircon REE data.
From: Active crustal differentiation beneath the Rio Grande Rift
Each pattern represents a single zone from LASS-ICP-MS depth profiling as described in Methods. Zones with U-Pb ages dated to early in the RGR history have flat HREE patterns, suggesting that garnet was present in these rocks at this time — consistent with higher pressures from thicker overlying crust.
