Work in this paper focuses on the data mining from chromatographic retention index data. A retention index database that contains about 50000 records of retention index is firstly established. Projection pursuit technique is then utilized to do data mining upon the data in order to find out some valuable information about the relationship between the retention indices and structural descriptors. A novel algorithm for projection pursuit is developed in this work. Samples of alkane, alkene and cycloalkane are investigated.

The age of adakitic dacite is about 514.2±8.5 Ma, and the age of eclogite from the northern margin of Qaidam basin is 494.6±6.5 Ma. Therefore, it is considered that the slab started its subduction in Late Cambrian, that the adakitic magma was formed at the subduction depth of about 75~85 km, and that the partial melting residues with garnet facies continued subducting and finally formed eclogite in Early Ordovician.

据其地球化学研究结果并结合该区埃达克质英安岩(5 14.2± 8.5Ma)和榴辉岩(494.6± 6 。5Ma)的年龄数据，推测柴北缘板片在晚寒武世开始俯冲，俯冲板片在 75～ 85km深处开始部分熔融形成埃达克质岩浆，而熔融残留部分继续俯冲，在早奥陶世形成含石榴石残留相的榴辉岩。
