As a result of the difference between various volcano eruption centers and multiperiodic activity of faulted structure and magma, Xiaoliukou volcanic complex rock in Luoyin area has confounding rock assemblages and complicated interrelationships between them, therefore the researchers had little interest in it over the years and prospecting in the volcanic complex rocks has being neglected. Based on the former works in recent years, the authors gain the new understanding in the characteristics and regularity of mineralization in volcanic complex rocks, and new development and breakthrough has been achieved in the prospecting works.
