Data report: anisotropy of magnetic susceptibility of sand layers and detrital carbonate layers in deep-sea sediments from the Labrador Sea, North Atlantic

Abstract

Microfabrics of sand and detrital carbonate layers were deduced from a study on magnetic susceptibility anisotropy of drill core sediments obtained from Site U1305 during Integrated Ocean Drilling Program Expedition 303. The magnetic minerals that contribute to the magnetic susceptibility and their anisotropy are assumed to be ferrimagnetic minerals according to their magnetic hysteresis analyses. Maximum magnetic susceptibility (Kmax) directions of those layers are largely scattered, but Kmax resides in the southeast margin of the diagram with 5°-10° inclination. Kmin is mostly concentrated in a vertical direction with a 5°-10°n orthwest plunge.
