Magmatic Ore Deposits in Small Rockbody in China

Tang Zhongli

Strategic Study of CAE 2002, Volume 4, Issue 6,   Pages 9-12

Abstract:

There is not any large deposit associated with giant layered igneous complex in China.But superlarge and large magmatic deposits have been discovered in many small intrusions.Therefore, research and exploration direction having great potentialities for the magmatic deposits ofsmall intrusions is defined.The Jinchuan and Panzhihua deposits represent two important types of the magmatic deposits in China.
