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

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.
