    Abstract:

    The cores, measurements of physical properties, well-logging and VSP data obtained from the Chinese Continental Scientific Drilling (CCSD) hole can be used to calibrate seismic reflectors and raise the reliability of seismic interpretation. Measurements of physical properties indicate that the rutile-bearing eclogite, due to its very high seismic velocity and density, can produce reflections and gravity anomalies. Numerical modeling demonstrates that the arch reflectors appearing at the CCSD site result jointly from the eclogites and the penetrating late shatter zone. Southeast of the CCSD main hole, there are quite a few such reflectors, implying that eclogite bodies exist in the extension direction of the surface eclogite body.
