By the use of the component sandstone electric conductivity model, the effect of the pore structure characteristic parameter to cementation exponent m and saturation exponent n in the Archie formula were studied. It can be found the cementation exponent m mainly reflects the pore space size and its sizes distribution. The m is bigger, the pore space is bigger, the throat is simpler, and the reservoir is better.

The Chondrite normalized REE pattern shows typical enrichment of LREE, with ∑REE peaking up to 318 mg kg^(-1) in central layer of the profile. Both Ce and Eu have a similar trend of variation in the profile, i.e. positive anomaly-negative anomaly-positive anomaly from bottom to top. The highest ∑REE value occurs where negative Ce and Eu anomaly and relatively higher Fe(superscript 2+)/Fe(superscript 3+) values also occur.

The decennary increment of AOD averaged from all stations was 0.05. As to mean values, the maximum was in Sichuan Basin of 0.649, and the second maximum in South-Xinjiang Basin of 0.411, while the minimum was in Qinhai-Tibet plateau of 0.125. As to seasonal mean, AOD in spring had the highest value, and then in summer, while the minimum was in winter.
