Abstract

Abstract

Magnetic susceptibility (κ) and density (ρ) were measured at 5.7 m depth intervals on drill cores from the main hole of the Chinese Continental Scientific Drilling (CCSD) Project. We analyzed the data by discriminant analysis employing SPSS 10.0 for Windows to test whether the lithology can be distinguished by petrophysical parameters. The density and magnetic susceptibility of the CCSD 100-2 000 m main hole are mainly controlled by the lithology. Lithology discriminant functions were constructed by means of the Enter Independents Together method. The results show that the total discriminant rate is 84.8%, while the rates of the serpentinized peridotite, orthogneiss, paragneiss, eclogite, amphibolite and retrograded eclogite are 100%, 87.1%, 89.7%, 89.6%, 96.7% and 63.7%, respectively. This research confirms that the petrophysical parameters of magnetic susceptibility and density can provide quantity constraints for the lithology discrimination of ultrahigh-pressure (UHP) rocks. Furthermore, it throws some light on the lithology determination, and may be useful in improving the interpretations of geophysical surveying and well logging.
