* Unrevelling reversals and periods of constant polarity of Earth?s magnetic field are of great importance in understanding processes of Earth?s liquid core ? Cretaceous Normal Superchron (CNS; 125 - 84 M io. years; Cande & Kent; 1995): well- established period of constant (normal) polarity; also period prior CNS of great interest for investigation of paleomagnetic field ? However, paleopoles from this period and from South America still scarce and show rather large dispersion ?» investigation of cretaceous dykes from Paraguay: obtain new directional and intensity data
