涟源坳陷煤反射率变化及其与深部断裂构造的关系

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。 

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.
