Discovery of cryptoexplosive breccia in Nanjinshan gold deposit of Beishan area,Gansu Province and study of metallogenic regularity;

Exploration on metallogenic regularity of gold-antimony deposit in Mazhala,south Tibet;

Geological characteristics and metallogenic regularity of underground brine ore in coastal areas of Weifang,Shandong Province;

Gas reservoir type and reservoir-forming rule of Huagou gas field;

Based on the study of the reservoir-forming rule, it is considered that the degree, of prospecting is still very low.

Based on the analysis of exploration wells information,seismic data and typical reservoir,the development features of unconformity structure,action of the unconformity to reservoir forming,and reservoir-forming rules and fine description method of unconformity traps in Jiyang Depression were researched.

On the base of discussion of the mineralization regularity and mechanism,prospecting direction in the area is proposed.

According the characteristic contrasting of the structure place,mine controlling factors,mineralizing action and forming types of the gold deposit in the areas around Wulaga gold deposit in Heilongjiang,the gold deposit mineralization regularity is summarized.

The deposit can be divided into three orebodies,geological characteristics and mineralization regularity,have been expounded in this paper.

Hainan Island contains abundant mineral resources and the metallogeny and mineralogenetic series on the island display many similarities to those in South China or the Nanling region but also have their own features.

In this paper, the basic characteristics of five metallogenic series are studied, and then, an discussion on regional metallogeny and mineralization model is made.
