Baddeleyite (ZrO2) is today recognized as the key mineral for dating the emplacement of mantle-derived igneous rocks, primarily gabbro and dolerite dykes and sills. The comment by Michard and Gasquet calls for a discussion on the significance of baddeleyite U-Pb TIMS dates of two dykes in the Bas-Draa inlier, dated at 1381 +/- 8 and 1384 +/- 6 Ma, presented in El Bahat et al. (2013-in this issue).
