Sr-Nd-Pb isotope geochemistry and tectonic setting of Devonian polymetallic metallogenic belt on the Southern margin of Altaid,Xingjing.;

Lithogeochemical characteristics and tectonic setting of volcanic rocks of Dianzhong Formation in the Coqen area,Tibet,China;

Geochemical properties of late Sinian basalt in the northwestern boundary of Tarim basin and its tectonic setting;

Type and structural setting of gold deposit in Qinling, orogenic belt;

Combining with the structural setting in the Ning er seismic area, we used GIS to synthetically analyze the structure marks of the earthquake preparation, including the structure in the seismic area, isoseismals, earthquake sequence, ground deformation zone, strong ground motion, focal mechanism solution and important macroanomalies.

On the basis of the analysis on the structural setting of the Huize,Yunnan,M_S5.

In order to investigate their genesis, source characteristics and tectonic background of diagenesis, the petrology and geochemistry are reported in this paper.

The chemical compositions of magmatite reflect the material source and the tectonic background,especially the content and distribution of microelements.

The study of sedimentary characteristics and tectonic background of the Carboniferous in Yeyungou area of South Tianshan will be great helpful to reconstruct the paleo geography and regional tectonics in northern margin of Tarim basin .

Through site investigation and project research on the characteristics of metallogenetic structure background,region metallogenetic geology,geophysics,geochemistry and etc,authors believe that the magma intrusion which caused by Yanshan Movement,supplied the heat source during the course of.

A Moving Object Detection Method Based on Background Reconstruction;

Moving object detection algorithm based on background reconstruction;

It theoretically proves that the algorithm based on background reconstruction can get rid of these mistakes.
