U-Pb LA-IC-PMS geochronological results and chondrite-normalized REE for monazite from sample AR736. (A) Tera-Wasserburg plot of monazite U-Pb results for the Bellachat micaschist (AR736). (B) Weighted averages of ²⁰⁷Pb-corrected dates diagram as function of monazite textural location. Error ellipses and uncertainties are ±2σ level. (C) Monazite trace element data from sample AR736. REE patterns normalized to chondrite values from McDonough and Sun (1995). (D) Plots of Y content and Dy_N/Lu_N ratios vs. ²⁰⁷Pb-corrected dates diagram. Bt-Ms: monazite in biotite-muscovite layers; St: monazite in fractures affecting staurolite cores; Pl: monazite in plagioclase inclusion.
