Rock magnetism and paleomagnetism of basalts at DSDP Leg 65 Holes

We investigated the magnetic and paleomagnetic properties of 77 basalt samples from Holes 482, 482C, 482D, 483, 483B, 485, and 485A in order to study the structure and development of the ocean's crust. During the course of this study, we measured the natural remanent magnetization, Jn, and its stability in an alternating magnetic field; the magnetic susceptibility, x; the saturation magnetization, Js; the saturation remanent magnetization, Jrs; the coercivity of maximum remanence, HCR; and the median destructive fields MDFn (for Jn) and MDFs for Jrs. A thermomagnetic analysis for Js and Jrs was also performed; these latter measurements were made on the same samples.
