Chad Deering (GMES) was quoted in a University of Wisconsin Oshkosh news story picked up by Science Daily and Phys.org. The story explains how a study led by Deering and UW-Oshkosh geologist Timothy Paulsen links zircon data from sandstones recovered from Earth’s major continental landmasses to the evolution of the Earth’s rock cycle and its oceans. Snehamoy Chatterjee (GMES) is also a co-author on the study.
“Continents tend to be worn down by weathering and rivers tend to transport this sediment to the oceans, leaving scattered puzzle pieces for geologists to fit together,” said Chad Deering, a Michigan Tech geologist and coauthor on the paper. “There is increasing evidence that important pieces of the puzzle are found in the ancient beach and river sediments produced through continental weathering and erosion.”
