New Caledonia – July 2022

Sampling Paleocene conglomerate-micrite-chert sections for magnetostratigraphy and dinocysts to determine the age of the island of New Caledonia, and young fluvio-lacustrine sediments for pollen, to determine the age of mountain building. In context of my NWO Veni project ROAD TO RICHES. Together with Margot Cramwinckel and Suzanna van de Lagemaat (Utrecht University), Prof. Pierre Maurizot and Willy Foucher (Geological Survey of New Caledonia).

Saint Barthelemy & La Désirade, French Antilles – January 2018
