Current IRM Conference
12th IRM Conference on Rock Magnetism
Virtual Meeting, June 1- 4, 2021
Iron minerals in the rocks of Earth's crust, its sedimentary cover and within speleothems contain fossilized records of ancient geomagnetic field activity, and in their physical and chemical characteristics they hold evidence of geological and environmental processes and events that have affected them. This conference will explore the state of the art in magnetic studies of natural materials, examine methods for extracting paleomagnetic and paleoenvironmental information through magnetic analysis, and assess what such studies are telling us about the history and workings of our planet and the solar system.
Dates and Session Format
The 12th IRM Conference on Rock Magnetism will be held virtually from June 1- 4 2021. The meeting will be hosted over zoom with four three-hour oral sessions, two keynote speakers and a poster session. The oral sessions are by invitation only, but we welcome poster presentations on any topics in rock and paleomagnetism. The conference format is designed to be interactive and in-depth, allowing extended periods of open discussion following invited lead talks on selected topics.
