On Research of Early Mesozoic volcanism in Fujian Province;

Mesozoic Volcanism and Constraint on Deep Geological Process in Yanshan Area;

Tectonic activities and volcanism in the basin have an influence on hydrocarbon generation of kerogen and its change.

Volcano acted differently on oceanic crust and continental crust after the global-scale dolomitite formation in Late Proterozoic:oceanic crust type volcanic action is characterized by magma gushing out quietly and evaping seawater;continental crust type volcanic action proformed violent eruption,dry ice refrigeration from baked carbonate layer leading to air .

Taking Chaobai River Bridge in Jingcheng Expressway as the engineering background, the article introduces the selection process of 3-phlon partial cable-stayed bridge structural system, and through the numerical analysis, compares the reactions of the different structural systems under the external action, and uses the measures using damper to reduce the earthquake effect of the structure.
