| sample_remark | Foden et al. (2020): Five samples of the post-tectonic A-type magmatic "Padthaway Ridge series" (Turner et al., 1992) were taken from scattered outcropping inliers in the Murray Basin. The analysed samples are the Mannum Granite (1109-7), the Marcollat Granite (JF07-118), the Mount Monster rhyolite porphyry (JF07-108), the granite at Monteith (KW08-15), and the granite at Kongal Rocks (JF07-114b). These each yielded abundant zircons and CL imagery showed well-defined magmatic concentric zonation. Concordia ages range between 486.1 +/- 1 Ma (Kongal Rocks, JF07-114b) and 470.1 +/- 1 Ma (Monteith, KW08-15). Between these limits, the Mannum Granite is 482.7 +/-2 Ma, the Marcollat Granite is 478.2 +/- 0.8 Ma, and the Mount Monster porphyry is 472.5 +/- 1 Ma. An undeformed granodiorite sample from drill hole PADD28 may also be a member of the Padthaway Ridge series, and has an age of 475.2 +/- 1 Ma. These ages are all consistent with earlier data that suggest that convergent deformation of this part of the Delamerian Orogen ceased at about 490 Ma (Foden et al., 2006). |
