摘　　要：对十几个典型金属矿床进行试验研究后 ,初步总结了各类金属矿床上方 ,有机烃气和汞气的常见模式 ,即不对称对偶双峰式、对称对偶双峰式、顶端单峰 (或峰丛 )式和双峰、单峰混合式。并从烃气和汞的运移通道 ,成矿期的热差效应 ,金属硫化物的氧化作用 。Through the experimental study carried out on more than ten typical metallic ore deposits, the common models of hydrocarbon gas and mercury gas above various metallic ore deposits are summarized. There are unsymmetrical double peak type, symmetrical double peak type, top single peak or cluster type, double and single peak complex type. The genesis of these anomaly models is analyzed from the view of transportation pathway of hydrocarbon and mercury, heat difference effectiveness during the ore forming period, oxidation of metal sulfide and oxidation reducing condition.
