Introduction. During the mid-Cretaceous, significant global perturbations in paleoceanographic, paleoenvironmental, and paleobiological events took place in response to the activity of large igneous provinces and oceanic crustal production, which resulted in extraordinary emissions of atmospheric carbon dioxide (Jenkyns, 2010).Major subdivisions of the Cretaceous System; Occurrence and distribution; Types of Cretaceous rocks; CorrelationChina’s 10,000-meter hole project heralds a new era in Earth Science.
