Discussion on Geological Features and Ore-forming Rule of the Hulalin Gold Deposit in Eerguna,Neimenggu;

Discussion on the Fetures of the Eerguna Metallogetic Belt and the Metallogetic Condition of Gold,Daxinganling;

Eerguna River ductile shear zone and its relation to gold mineralization in Inner Mongolia;

Based on the geological and geochemical studies of Mesozoic volcan ic rocks from the Manzhouli-E erguna region, it is suggested that the Mesozoic volcanic rocks were developed on the tectonic background of the Mongolia-Ehucik e residue ocean that was closing in the scissors form, but each formation is dif ferent in tectonic character.

Taking the descendants of Chinese-Russian, living along Erguna River, as example, the author analyzed the concepts of marginal culture, marginal person, and bilingual phenomena and the internal relation among them.

The Eerguna metallogenic belt is an important nonferrous metal metallogenic belt in the Northeast China.

In order to explore concealed ores in the south section of Eerguna metallogenic belt,geophysical exploration methods such as combination of audio magnetotellurics prospecting and induced polarization(IP)are used.
