Mission: Use the carbonate and siliciclastic sediments within cave and karst settings to explore environmental and climate change, geomagnetic field behavior, identify the effects of land use, and reveal our anthropological heritage.
Mission: Use the carbonate and siliciclastic sediments within cave and karst settings to explore environmental and climate change, geomagnetic field behavior, identify the effects of land use, and reveal our anthropological heritage.
Stalagmites, flowstones, and siliciclastic sediments accumulating in caves and karst are natural archives of climate, geomagnetic, and anthropological history. By collecting carefully oriented samples and measuring them at the Institute for Rock Magnetism, we can uncover high-resolution records for a variety of phenomena. We can also use such samples to document the timing and conditions that formed the caves themselves.
Cave and karst environments occur on every continent and our research group collaborates with cave scientists from around the world. We love working and learning in the field and we share a strong commitment to cave preservation.
