STUDY OF GINI COEFFICIENT ON THE ANALYSIS OF VITRINITE REFLECTANCE MEASUREMENT—A CASE STUDY OF MIOCENCE SEDIMENTARY ROCKS OF THE WESTERN TAIWAN

In order to evaluate the correlation between variance of measured vitrinite reflectance data and Gini coefficient,34 Miocene sedimentary rock samples were collected from western Taiwan.Their vitrinite reflectance and Gini coefficients were measured and calculated.The good correlation evaluating indicates that the Gini coefficient can be applied as a quantitative index in the variation of vitrinite reflectance mea-sured.
