摘要

量测了34个台湾西部地区中新世岩样的镜质体反射率并计算了Gini系数,探讨了量测镜质体反射率的不均性结果与其Gini系数之间的相关程度。结果显示:量测平均镜质体反射率的不均性结果与Gini系数之间有良好的相关性;说明Gini系数在判识镜质体反射率在不均性的量测结果上具良好的量化性指标。

Abstract

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.
