Sm Nd isotope age and its geological significance of epimetamorphic rock series in the Qinglong area, eastern Hebei province;

Study on igneous reservoir forming conditions and reservoir prediction of Qinglongtai area;

Natural gas play targets in Gulong area,Songliao Basin;

Based on the detailed determination under microscope,the comparison with the texture,shape and composition of iron stromatolites,as well as on the analyses and studies of stable isotopes and organic geochemistry of oolitic ores from the Xuanlong area,the paper proposed preliminarily that oolitic ores actually are coated grains by the formation of microorganisms.

To reveal the relationship between the changes of Giant Panda habitats and environmental alterations resulted from human activities at a watershed scale,the digital elevation model of 1∶250000 was used to select two watersheds(Shouxi and Yuzixi) and Giant Panda potential habitats in Wolong area.

Five of top soils and two yak samples were collected from Wolong area and analyzed to determine the concentration levels,altitude distribution,sources,and toxicity equivalency quantity(TEQ)of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs),co-planar polychlorinated biphenyls(co-PCBs)and polychlorinated naphthalenes(PCNs).
