The eastern area of Inner Mongolia is in the joint between the Siberia plate and the Sino Korean plate, where there are many rich ore deposits as a result of the injection of deep magmas, volcanos and diagenetic alteration. Under these special geotectonic environment, many special rocks, such as hydrothermal sediments, were formed. Hydrothermal sediments have been discovered and reported in China in the eighties and some were discovered later on. The discovery of these sediments in this area is reported here for the first time(Fig 1). Hydrothermal resources (hydrothermal solutions, hot water, the endogenous material flow) are usually from deep in the ground (could be from the mantle) to the earth surface to form rocks such as travertine, tufa, sinte, exhalite, exhalative hydrothermal sediments.The stripe sediments in Jirihe, Zhalute of Inner Mongolia were created under these conditions and they contain a lot of organic species(Fig 1). It is very helpful to reveal the origin of some shale oil or shale gas by understanding the relationship between these hydrothermal sediments and the hydrocarbon they contain through the systematic study of their chronology, composition, minerals, diagenetic alteration, geochemistry, nanostructures, organic species and hydrothermal hydrocarbons.
