Paleomagnetic studies of crystalline rocks (ages ranging from Lower Jurassic to Lower Cretaceous) from 5 sites located in area Argentine Islands and coast Antarctic Peninsula (65º15'S // 64°15'W) have detected the two main components of remanent magnetization: component of norrmal polarity (A) has an average direction Dm=342° and Jm=-44°, component of the reverse polarity (B) in relation to a modern geomagnetic field (Dm=144° and Jm=43°). The results of laboratory researches of spectra PTRM have established that in some samples at heatings there is a self - reverse of remanent magnetization.
