Cretaceous system
(initial capital letter)Geology. the Cretaceous Period or System.Cretaceous is the name given to a period of time in Earth 's history (i.e., Cretaceous Period) from 145.6 to 65 million years ago. Also, all the rocks that formed during that time have the same proper name of Cretaceous (i.e., they are referred to as the Cretaceous System). Said differently, the Cretaceous System is the rock record of events ...The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series.Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian.

Technical expert Wang Chunsheng, who recently joined the operation, stated that drilling a borehole which is more than 10,000 metres deep is a bold step to explore the Earth's unknown territory and enhance the boundaries of human understanding. Cretaceous Period - Rocks, Fossils, Climate: The rocks and sediments of the Cretaceous System show considerable variation in their lithologic character and the thickness of their sequences. Mountain-building episodes accompanied by volcanism and plutonic intrusion took place in the circum-Pacific region and in the area of the present-day Alps.
Cretaceous Period, Interval of geologic time from c. 145 million to 66 million years ago. During the Cretaceous the climate was warmer than today. In the seas, marine invertebrates flourished, and bony fishes evolved. On land, flowering plants arose, and insects, bees in particular, began their thriving partnership with them. The drilling process will penetrate more than 10 layers of the Earth's crust and reach the Cretaceous system, consisting of rock dating back up to 145 million years.
