The location pole is the Fisher mean of the tilt-corrected site VGPs. For comparison, Meert & Stuckey also report a Mean-TC pole from the mean tilt-corrected direction (233.4/+36.9): 13.2 S, 219.0 E (dp 4.7, dm 8.0). The 18 sites in the `sites` list are the stable-direction pole sites; excluded from the mean (retained in the contribution as result_quality=b for the field tests) are the reversed, poorly grouped site 15-TS, the Cambrian boulder-conglomerate clasts (6-CT; conglomerate test), and the ca. 1.33-1.28 Ga dike / baked-contact component rows of 3-SG and 4-GM. Per-site VGPs were recomputed (signed) from the listed tilt-corrected directions, so they are internally consistent with the directions and may differ slightly from the rounded VGPs in Table 1 (and in hemisphere for the excluded younger-pulse rows). The pole is supported by positive fold, conglomerate, and inverse baked-contact tests. Age 1466 Ma (1448-1484) adopted from du Bray et al. (2021); originally dated 1476 +/- 16 Ma (Van Schmus et al., 1993). >>>>>>>>>> tab delimited sites site location result_type result_quality method_codes citations geologic_classes geologic_types lithologies bed_dip bed_dip_direction lat lon age age_sigma age_low age_high age_unit dir_tilt_correction dir_dec dir_inc dir_alpha95 dir_k dir_n_samples dir_comp_name vgp_lat vgp_lon vgp_dp vgp_dm description 1-BH St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Pluton Granite 10 240 37.7 269.595 1466.0 1448.0 1484.0 Ma 0 229.0 23.0 19.0 11.0 7 Conglomerate-test target site; clast directions are randomly distributed (positive conglomerate test). 1-BH St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Pluton Granite 10 240 37.7 269.595 1466.0 1448.0 1484.0 Ma 100 229.6 13.2 19.0 11.0 7 -26.0 212.3 9.9 19.4 2-KG St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Pluton Granite 10 240 37.68 269.615 1466.0 1448.0 1484.0 Ma 0 239.6 31.0 14.0 44.0 4 2-KG St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Pluton Granite 10 240 37.68 269.615 1466.0 1448.0 1484.0 Ma 100 239.6 21.0 14.0 44.0 4 -16.1 207.7 7.7 14.7 3-SG St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Volcanic Dike Diabase 10 240 37.6 269.65 1280.0 1330.0 Ma 0 44.0 50.0 9.8 28.0 9 b 3-SG St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Volcanic Dike Diabase 10 240 37.6 269.65 1280.0 1330.0 Ma 100 44.0 50.0 9.8 28.0 9 b 53.3 356.9 8.8 13.1 3-SG St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Pluton Granite 10 240 37.6 269.65 1466.0 1448.0 1484.0 Ma 0 234.0 39.0 11.0 39.0 6 c 3-SG St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Pluton Granite 10 240 37.6 269.65 1466.0 1448.0 1484.0 Ma 100 234.7 29.0 11.0 39.0 6 c -16.2 214.7 6.7 12.1 4-GM St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Extrusive Pyroclastic Flow Ignimbrite 10 240 37.569 269.635 1466.0 1448.0 1484.0 Ma 0 263.0 53.0 9.5 41.0 7 c 4-GM St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Extrusive Pyroclastic Flow Ignimbrite 10 240 37.569 269.635 1466.0 1448.0 1484.0 Ma 100 259.0 43.7 9.5 41.0 7 c 7.3 206.4 7.4 11.9 4-GM St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Volcanic Dike Diabase 10 240 37.569 269.635 1280.0 1330.0 Ma 0 325.0 59.0 10.0 19.0 12 d 4-GM St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Intrusive Volcanic Dike Diabase 10 240 37.569 269.635 1280.0 1330.0 Ma 100 325.0 59.0 10.0 19.0 12 d 62.8 195.2 11.1 14.9 4-GM St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Extrusive Pyroclastic Flow Ignimbrite 10 240 37.569 269.635 1280.0 1330.0 Ma 0 76.0 45.0 6.8 66.0 8 e 4-GM St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Extrusive Pyroclastic Flow Ignimbrite 10 240 37.569 269.635 1280.0 1330.0 Ma 100 76.0 45.0 6.8 66.0 8 e 26.4 345.3 5.4 8.6 5-GM St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Extrusive Pyroclastic Flow Ignimbrite 10 240 37.571 269.62 1466.0 1448.0 1484.0 Ma 0 246.8 63.0 15.4 26.0 5 5-GM St. Francois Mountains i g LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-F 10.1029/2000TC001265:10.3133/pp1866 Extrusive Pyroclastic Flow Ignimbrite 10 240 37.571 269.62 1466.0 1448.0 1484.0 Ma 100 245.1 53.1 15.4 26.0 5 3.5 220.5 14.8 21.3 6-CT St. Francois Mountains i b LP-DIR-T:LP-DIR-AF:LP-IRM-3D:DE-BFL:DE-FM:FS-FD:SO-SM:ST-G 10.1029/2000TC001265 Sedimentary Conglomerate Conglomerate 10 240 37.573 269.7 500.0 50.0 Ma 0 150.0 49.0 60.0 1.0 13 Conglomerate-test target: Cambrian boulder conglomerate whose clasts are both granitic and volcanic material (Meert & Stuckey, 2002; depositional age ~500 Ma).
