Jan Zalasiewicz introduces the field of geology, its fundamental role in understanding the Earth and other planets, and its economic importance in the finding and exploitation of resources. He explains how geologists work today, and describes major discoveries such as plate tectonics, and the field's exciting frontiers such as the geology of Mars.
Jan Zalasiewicz is a Professor in the Department of Geology at the University of Leicester, and before that worked at the British Geological Survey. A field geologist, palaeontologist, and stratigrapher, he teaches various aspects of geology and Earth history to undergraduate and postgraduate students, and is a researcher into fossil ecosystems and environments across over half a billion years of geological time. He has published over a hundred papers in scientific journals, and several books with Oxford University Press, including Rocks VSI (2016), and The Planet in a Pebble (2010).
