Palaeomagnetism of Upper Cretaceous—Lower Tertiary igneous rocks from Central Argentina
Summary. From nine Upper Cretaceous—Lower Tertiary (85 ± 5–66 ± 5 Ma) volcanic hills in Central Argentina (33°S, 65°W), 26 hand samples were collected yielding a palaeomagnetic pole at 45°E 70°s (A 95 = 12.1°; k= 13.6; N = 12) after AC cleaning. Three sites show normal and nine reversed polarity. Th...

| Sumario: | Summary. From nine Upper Cretaceous—Lower Tertiary (85 ± 5–66 ± 5 Ma) volcanic hills in Central Argentina (33°S, 65°W), 26 hand samples were collected yielding a palaeomagnetic pole at 45°E 70°s (A 95 = 12.1°; k= 13.6; N = 12) after AC cleaning. Three sites show normal and nine reversed polarity. This pole is close to the pole for the late Cretaceous (69 Ma) Andacolo Series. Copyright © 1983, Wiley Blackwell. All rights reserved |
