About 60% of the samples show clear gneissosity, but 40% of the samples have less clear gneissosity. The samples with gneissic fabric show magnetic anisotropy. The maximum value of H_C and I_R, and the minimum values of X_ coincide with the lineation within a foliation plane. During thermal demagnetization of the samples having stable NRM's, the NRM declinations are gradually shifted toward the direction of lineation, and they are stabilized in a plane, within the rock, having well developed foliation. The anisotropy tendency is more clearly observed by using the H_C and I_R values than X_ values. Two kinds of virtual geomagnetic pole (VGP) positions are identified from the Skarvsnes area. The former is consistent (latitude 11.2°S, longitude 16.0°E) with the previous results reported from the Lutzow-Holm Bay area, and the latter (latitude 2.5°S, longitude 63.2°E) reflects the magnetic anisotropy resulting from the lineation.}, pages = {37--46}, title = {THE MAGNETIC ANISOTROPY OF GNEISSIC ROCKS FROM THE SKARVSNES AREA, EAST ANTARCTICA}, volume = {6}, year = {1993} }
