Opis

A first step in polar research that takes account of both ends of the Earth: an interhemispheric comparison of the geological evolutions of the Antarctic and Arctic regions leading to the late Cenozoic glaciation. The 37 papers constitute the proceedings of a NATO workshop in Bremen, West Germany, i
