Selecting two geologic models:dome model with homogeneous overlying medium and dome and fault model with overlying fractured formation,over which a ordinary 3 D seismic data acquisition,processing and analysis have been done and following results are obtained:① seismic physical model experiment can fully model 3 D geologic structural body;② wavefield feature of eac.

This paper introduces various data about Longshan dome (brachy-anticline) in Xinshaocounty, Hunan Province, China, and demonstrates that the dome (brachy-anticline) doesnot exist there on the basis of the definitions of dome and brachy-anticline, geologic sectionsand occurrence of the strata of Longshan area, as well as proposes a new viewpoint on thestructure of the district.

Transcaliosum interfornix approach to microsurgically remove the tumors of the third ventricle;

According to the recent understandings of the tectonic setting of Xiao Qinling area,it is put forward that the geological model of volcanic thermal dome gold being formed in the metamorphic complex cone under A-type subduction after studying of geology and minerals in this area.

This area underwent a widespread tectonic thermal event in Haixi period resulting in dome structure,extending fault ,secondary brittle fracture belt and brittle tough fracture belt,which played very important role to contol gold mineralization in this area.
