Abstract
Abstract. Continental scientific drilling can be regarded as a telescope into the Earth's interior because it provides process insight and uncompromised samples of rocks, fluids, and even sampled from the deep biosphere from the Earth's surface to great depths. As one of the three founding members of the International Continental Scientific Drilling Program (ICDP), ICDP China has made great achievements in many scientific drilling-related research fields. Based on the ICDP participation it attracted global attention of scientists and set up not only the Chinese Continental Scientific Drilling (CCSD) Program in 2001 but also a growing number of ambitious drilling projects in the country. The 5158 m deep borehole of the CCSD project at Donghai County in the Sulu ultrahigh-pressure metamorphic terrain demonstrates that large amounts of crustal rocks of the South China Block have been subducted to at least 120 km, followed by rapid uplift. After successful completion of drilling at Donghai, several continental scientific drilling projects were conducted with funding of the Chinese government and partially with support of ICDP, resulting in a total drilling depth of more than 35 000 m. These projects encompass the Continental Environmental Scientific Drilling Program of China, the Scientific Drilling Project of Wenchuan Earthquake Fault Zone, the Continental Scientific Drilling Project of Cretaceous Songliao Basin, and the Program of Selected Continental Scientific Drilling and Experiments. On the occasion of the 20th anniversary of the ICDP and the 15th anniversary of the CCSD Program, this paper reviews the history and major progress of the CCSD Program.
Highlights
Flying into the outer space, going into the Earth’s interior, and investigating the deep ocean floor have been dreams of mankind for the exploration of the nature
Twenty years have passed since the foundation of the International Continental Scientific Drilling Program (ICDP) in 1996
The ongoing Continental Scientific Drilling Project of Cretaceous Songliao Basin started in April 2014 and will recover continuous highresolution terrestrial achieves and Cretaceous climate change (Wang et al, 2008, 2013a, b). Besides these ICDP projects, from 2008 to 2012 the Chinese government supported the Program of Selected Continental Scientific Drilling and Experiments, which consists of seven drilling projects on some key problems in continental dynamics
Summary
Flying into the outer space, going into the Earth’s interior, and investigating the deep ocean floor have been dreams of mankind for the exploration of the nature. The ongoing Continental Scientific Drilling Project of Cretaceous Songliao Basin started in April 2014 and will recover continuous highresolution terrestrial achieves and Cretaceous climate change (Wang et al, 2008, 2013a, b). Besides these ICDP projects, from 2008 to 2012 the Chinese government supported the Program of Selected Continental Scientific Drilling and Experiments, which consists of seven drilling projects on some key problems in continental dynamics. On the occasion of the 20th anniversary of the ICDP and the 15th anniversary of the CCSD Program, we present a brief review of history and achievements of the CCSD Program
