Multiple remagnetizations of lower Paleozoic limestones from the Taconics of Vermont
The natural remanent magnetizations in some upper Cambrian and middle Ordovician limestones from the Taconics of Vermont (~44°N 287°E) are multicomponent and can be attributed to early Paleozoic, late Paleozoic and Cretaceous-early Tertiary remagnetizations. A northwesterly and up magnetization found at 2 sampling localities, characterized by maximum unblocking temperatures of about 350°C, has directions prior to tilt correction corresponding to Ordovician reference poles for North America and is likely to represent a Taconic remagnetization. A shallow, southerly magnetization found at a third locality, with unblocking temperatures that range to about 500°C, has directions corresponding to a Permian (Kiaman and Alleghenian) remagnetization. Common to all 3 sampling localities is a low (up to 300°C) unblocking temperature overprint similar in direction to Cretaceous to Paleocene reference poles.
