中国大陆科学钻探终孔及研究进展

Completion and achievement of the Chinese Continental Scientific Drilling (CCSD) Project

摘要: 提要：中国大陆科学钻探工程经过1309天的努力奋斗，于2005年1月23日，钻井终孔深度达到5 118.20 m。成为中国钻探技术发展的新里程碑。全面研究正在开展，在巨量物质深俯冲、超高压深俯冲与折返的精确定年、超高压岩石的原岩形成背景、上地幔流变学、地幔特殊新矿物发现、地下流体异常及地下微生物发现等方面已取得重要进展。

Abstract: Abstract：After 1309 days of hard work, the Chinese Continental Scientific Drilling (CCSD) project drilled a total depth of 5118.20 m and reached its target depth by January 23th, 2005. The well completion is a new landmark in the development of China′s drilling technology. A comprehensive on-going study is being carried out and great advances have been made in the following aspects：precise dating of deep subduction of voluminous continental materials, UHP deep subduction and exhumation, setting of formation of protoliths of UHP rocks, upper mantle rheology, discovery of special, new mantle minerals and discovery of subsurface fluid anomalies and subsurface microorganisms.
