The Very Low Grade Metamorphism in the Upper Paleozoic in Xinlingol Area of Inner Mongolia, NE China: Evidence from Studies of Illite and Vitrinite Reflectance
This paper deals with the genetical characteristics of illite in the Upper Paleozoic pelitic rocks in the Xilingol regions of Inner Mongolia using D/max-2500 X-ray diffraction and the relationship between organic matter vitrinite reflectance and metamorphic temperature. It is concluded that some horizons in the studied area have the potential of generating oil and gas resources.
