This dataset includes organic carbon measurements on rock samples collected upper Cretaceous deposits found in Cerro Cazador (Magallanes Basin, Patagonia, Southern Chile) in March 2020. The dataset was collected during the Chile Slope System geologic field trip that took place between February and March 2020, and led by Steve Hubbard, Brian Romans and Lisa Stright. Samples were collected along a 525-m geologic section using hammers and shovels
