Detailed paleomagnetic data can be obtained from continuous measurements of U-channels extracted from sedimentary cores using a small-diameter pass-through magnetometer and signal-response pick-up coils. Spatially, features of 3-5 cm size can be resolved. An analysis of the demagnetization data based on the angular dispersion of the directions between successive demagnetization steps and the downcore changes in the rate of intensity decrease can rapidly distinguish between intervals with well-identified magnetic components and zones characterized by a more complex behavior during demagnetization, as well as directly measure the magnetic susceptibility and measure most rock magnetic properties along the U-channels. Thus, all parameters necessary for a complete paleomagnetic study of sediment cores can be obtained directly from U-channels without extracting individual samples. This equipment allows the measurement and complete demagnetization of up to 10 single samples in less than 1 hr, via techniques similar to those developed for the U-channels.
