Abstract:

Aimed at the 7th member of Middle Jurassic(J2d7)in Yuqia area,we undergo the solid mineral development and the
comprehensive utilizationstudy. Accordingly,this study firstly discussed the tectonic background and sedimentary environment
of the oil shale formed in Yuqia area based on the data from the field outcrop measured section,drilling,seismic data,sample
analysis,and so on. Then economic and technological evaluations for the oil shale deposit were made according to seismic
data and sample analysis. Assessment results show that the oil shale in Yuqia area is characteristic of high quality,shallow
burying and big reserve. Thus it has a great potential value for development. Finally,taking into consideration developmental
experiences in the world and the actual condition of Qaidam Basin,for the first time the strategy for mining and utilization of
oil shale deposit in Yuqia area is proposed in this paper

Key words: oil shale, Dameigou group, Yuqia Area, northern margin of Qaidam Basin, Qaidam Basin
