Research Interests and Activities

Prof. Heller has contributed enormously to the interdisciplinarity of palaeomagnetism and is one of the founders of environmental magnetism. He gave proof of this by numerous multidisciplinary publications in important journals such as Nature. The recently published book Environmental Magnetism (Evans & Heller, 2003), reflects his broad research interests. In this book, environmental magnetism techniques are made easily accessible to a diversified public. The most important scientific achievements of Prof. Heller are the investigations on loess/palaeosol sequences world-wide, particularly in China where he established the basis for investigations of the most important continental palaeoclimate archives. During his 24 years of research on loess he successfully investigated loess/palaeosol sections in China, central Asia, eastern Europe and Argentina. Prof. Heller contributed much to the explanation of the magnetic mineralogy, the origin of the natural remanent magnetisation and the palaeoclimatic significance of loess/palaeosol sequences by connecting classical and new rock magnetic techniques with non-magnetic analyses. Prof. Heller has also been active in other fields of environmental magnetism such as lake sediments, biomagnetism and pollution studies. Classical palaeomagnetism is another research activity of Prof. Heller. He studied intensively magnetostratigraphy, tectonics and rock magnetism of the Permian/Triassic boundary in China, Pakistan, Russia and Italy which are vital regions for establishing the geochronology of this important stage of the Earth's history. Moreover, he dealt with magnetostratigraphy and tectonics of the Andean Cordillera, the Swiss Alps and Jura mountains and he contributed also to the magnetostratigraphy of the Cretaceous/Tertiary boundary in Italy. Under his guidance, the palaeomagnetic laboratory at the ETH Zürich has become one of the leading palaeomagnetic laboratories in the world. In this context, he has also been active in the development and application of new rock magnetic measurement techniques such as the high field torque magnetometer and the coercivity spectrometer.
