Paleomagnetism of the Beemerville (New Jersey) Alkaline Complex

Stable remanent magnetism in the Late Ordovician Beemerville (New Jersey) alkaline complex (435 m.y.) is carried by secondary hematite resulting from supergene weathering prior to deposition of the Lower Silurian Shawangunk Conglomerate. The mean vector from four stable sites (of eight sampled) is D = 163°, I = 22° (κ = 23, α₉₅ = 20°) and gives a virtual geomagnetic pole at 35°N., 126°E., δp</em> = 9°, δm</em> = 18°. *Present address: Manlius Pebble Hill School, Manlius, New York 13104
