Abstract:
Paleomagnetic analyses of the natural remanent magnetization of >1700 vertically oriented sediment samples from Integrated Ocean Drilling Program (IODP) Holes U1319A, U1320A, U1322B, and U1324B in the northern Gulf of Mexico reveal complex magnetostratographic signals for the Brazos-Trinity and Ursa region carried by detrital iron oxide minerals. Additionally, gyroremanent magnetization was observed to form during alternating-field demagnetization of samples containing an enhanced amount of magnetic iron sulfide minerals. Most characteristic remanent magnetization inclinations are reasonable for the site latitudes. Stable declinations allow for azimuth correction of the formerly unoriented drill cores.
