In this area, rocks are Carboniferous, with younger strata above them that have been identified through well data and high-resolution 3D seismic profiles. Among these strata, seven unconformities are observed and distributed at the bases of： the Permian Jiamuhe Formation, the Permian Fengcheng Formation, the Triassic Baikouquan Formation, the Jurassic Badaowan Formation, the Jurassic Xishanyao Formation, the Cretaceous Tugulu Group and the Paleogene. On the basis of balanced sections, these unconformities are determined to have been formed by erosion of uplifts or rotated fault blocks primarily during the Mesozoic and Cenozoic. In conjunction with the currently understood tectonic background of the sur- rounding areas, the following conclusions are proposed： the unconformities at the bases of the Permian Jiamuhe and Fengcheng formations are most likely related to the subduction and closure of the Junggar Ocean during the late Carboniferous-early Permian; the unconformities at the bases of the Triassic Baikoucluan and Jurassic Badaowan formations are closely related to the late Permian Triassic Durbut sinistral slip fault; the unconformities at the bases of the middle Jurassic Xisbanyao Formation and Cretaceous Tugulu Group may be related to reactivation of the Durbut dextral slip fault in the late Jurassic -early Cretaceous, and the unconformity that gives rise to the widely observed absence of the upper Cretaceous in the northern Junggar Basin may be closely related to large scale uplift. All of these geological phenomena indicate that the West Junggar was not calm in the Mesozoic and Cenozoic and that it experienced at least four periods of tectonic movement.展开更多

Methods: The clinical study involving observation of 135 patients of SARS was conducted in the randomized, synchronously controlled and open way. The patients were divided into two groups, 68 in the ICWM group and 67 in the c ontrol group, all of whom were treated with the same basic treatment of western medicine, but to the ICWM group, Chinese drugs for clearing Heat, detoxifying an d removing Dampness were given additionally. The comprehensive effect on relievi ng fever, cell mediated immunity, pulmonary inflammation and secondary infect ion was compared between the two groups. Results: The therapeutic effect in the ICWM group was better than that in the control group in such aspects as steadily lowering body temperature, alleviating general symptoms, accelerating the absorption of pulmonary infiltra tion and easing cellular immunity suppression. Conclusion: The therapeutic effect of ICWM is better in treating SARS than that of western medicine alone.展开更多
