| Abstract: | The study of Chang 8 sandstones from the Upper Triassic Yanchang Formation in the Zhenjing area, Ordos Basin, was undertaken to unravel the characteristics of chlorite minerals, such as type, occurrence, formation time and origin and so on. The chlorite minerals in the Chang 8 sandstones present as three different occurrences: terrigenous clastic chlorite, authigenic chlorite and alteration chlorite. Among them, the authigenic chlorite occurs as grain-coatings, pore-linings and pore-fillings, with the pore-... |
