引用

Global Geology 1999年第2期4卷 206-209页

作者： Wang Daping, Zhou Ji and Yan Ping (Heilongjiang Nonferrous Geoprospecting Academy,Harbin,150046)

The paper expounds the metallogenic characterist ic s of Jiawula multimetals deposit in China and Uran multimetals deposit in Mongol ia. Comparative study shows that both deposits are volcanic hydrothermal mineral ization with same epoch(Mesozoic), same source, same temperature, and same miner al assemblage, but volcanic structure are different. Therefore, both deposits ca n draw on experience of each other and supplement in future of second time ore- prospecting, and point out the new direction of ore-prospecting.
