Genesis and characteristic of weak intercalation existed in the red-bed slope of Badong formation in southwestern Hubei Province

According to the weak mud intercalation existed in the red-bed slope of Triassic period in southwestern Hubei Province,we studied the genesis of the intercalation from the geological sedimentary history and regional tectonic mechanics,and analyzed the changing of mineral and grain size during its formation.By doing indoor test we studied the strength characteristics and expansibilities of weak intercalation.After the research we made whole understanding of intercalation in this region from genes...
