The San Francisco City Hall was open for all participants the whole evening. The building was fi rst open to public in 1915. Its dome, which owes much to Mansart‘s Baroque dome of Les Invalides, Paris, is the fi fth largest dome in the world. The City Hall was build by Arthur Brown Jr. who also designed San Francisco‘s War Memorial Opera House, Veterans Building, Temple Emanuel, Coit Tower and ...

The conventional K-Ar dating method was applied to the 1986 dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in 1986 gives a whole rock K-Ar “age” of 0.35±0.05 million years (Ma). Mineral concentrates from the dacite which formed ins 1986 give K-Ar “ages” from 0.34±0.06 Ma (feldspar-glass concentrate) to 2.8±...

geophysical data are always affected by different sources of anomaly. these sources are classified in to three groups: first group is relatively deep sources commonly called as regional effects, second group is near surface sources or local effects and third group is high frequency noises. the only common way to separate the anomaly is separation with respect to the signal frequency. there are ...

RATIONALE Pseudomyxoma peritonei is an unusual clinical condition, and the appendix and ovaries are reported as the primary sites. PATIENT CONCERNS A 44-year-old man who was reported a 3-month history of lower abdominal pain and distention, along with increased abdominal girth, was admitted with a palpable tender mass in the central lower abdomen. DIAGNOSIS Ultrasonography showed a large we...

We describe a new short cut strategy to image the sediments and salt edge around a salt flank through an overburden salt canopy. We demonstrate its performance and capabilities on a synthetic acoustic seismic data from a Gulf of Mexico (GOM) style model. In this strategy, we first redatum the surface shots from a walk away Vertical Seismic Profile (WVSP) survey to be as if the source and receiv...

Hart et al. (1995) postulated that large meteorite impacts may generate characteristic magnetic signatures due to thermal resetting of remanent magnetism, as a consequence of the impact process. Their postulation is based on the results of a study of the ca. 2 Ga Vredefort structure which shows that the remanent magnetism of rocks from the core of the structure was reset penecontemporaneously w...

Dome A is the highest point on the Antarctic Plateau, and the Chinese Expedition Team first arrived here in 2005 January. It is an excellent site for astronomical observations. The first-generation Chinese Antarctic optical telescope CSTAR has been operating on Dome A since 2008 January. The second-generation Chinese telescopes known as the Three Antarctic Survey Telescopes (AST3) are currently...

Geological maps have wide coverage with low acquisition difficulty. When other geological survey data are scarce, they a valuable source of structure information for modeling. However, structures large deformation, map has difficulty meeting the requirement its 3D Therefore, this paper takes dome as an example to explore modeling method based on maps, DEM and related knowledge. The includes: (1...
