THE CHARACTERISTICS OF VITRINITE REFLECTANCE OF ANTHRACTIVE IN LIANYUAN DEPRESSION AND THEIR RELATION TO THE DEEP-SEATED FAULT STRUCTURE

摘要: 研究了区内近30个矿井中煤的反射率变化特征及分布规律,结合地质、航磁资料,确认了区内上古生界地层下有一条北西向压扭性基底隐伏断层。

Abstract: By means of measuring the vitrinite reflectance of the anthractive from nearly thirty mines in the Lianyuan depression, Hunan province, this paper researches their various characters and distribution regularity. Meanwhile, summing-up themand the material of geology, air magnetic survey and remote sensing, author considers further that there is a basementblind fault of the pressure-shearing nature in northwest direction beneath the strata of the opper palaeogoic erathem.
