Abstract

Abstract

Eclogite, one of the important lithologies in the main hole of Chinese Continental Scientific Drilling (CCSD) Project, is distributed over 3 245 m above the sea-level. Gamma-ray, compensating density and neutron well-logging and so on can be used to distinguish the ecolgite from others in the main hole. In the paper, because of diverse mineral and chemical components and well-logging responses, eclogites are classified in terms of three aspects: origin, content of oxids and sub-minerals. The studied statistical method in the paper is used to evaluate 11 kinds of reconstructed eclogites. As a result, eclogites can be divided into 6 types by using of well logs. With the identification of these six types in the main hole, 20 sections of eclogites are sorted and analyzed, which will provide important information for geological research of CCSD.
