Strike-slip pull-apart process and emplacement of Xiangshan uranium-producing volcanic basin;

Geological conditions for ore-forming process and prospecting direction of the U-Mo polymetallic deposits in Guyuan volcanic basin;

Lingquan volcanic basin is located in the mid-southern segment of known Rrguna-Kelulun Eastnorth-trending volcanic rocks uranium metallogenic belt,it is on the same belt with Telechuf Field of Russia and Durnuot Field of Mongolia.

Some advances in the study of volcanic geology and a hazards analysis of Tianchi volcano;

Field observation of volcanic earthquakes and initial research for stress condition of Changbaishan Tianchi volcano;

The researches of volcanic earthquake activities recorded at Tianchi Volcano Observatory(TVO) since 1999 showed that the volcanic earthquake activities changed their features before or after the occurrence of the intermediate-deep earthquakes,magnitude 5.

Historical material records show there were a large number of seismicities in Wudalianchi volcano during 1720～1721,which provides us with abundant volcanic earthquake information.
