Dr. Li Da is visiting the our research group to carry out isotope analyses of approx. 525 million years old limestone from China. These limestone comes from the Cambrian explosion, a period of approx. 540-520 million years ago, when skeletonized, marine animals suddenly diversified into new species. The study will compare the stable isotopic composition of uranium deposited in a Chinese basin to a time-equivalent basins in Siberia. These efforts will help us understand global oxygen conditions in the oceans during the Cambrian explosion.
Dr. Li Da stays in the Section for Geobiology and Mineralogy for three months from September 11th, 2016.
