摘　　要：赤峰市莲花山金矿区南部为大片风积黄土覆盖区，壤中气汞测量圈出了许多气汞异常，其中在已开采的４号、５号金矿脉上，气汞异常的形态、规模和强度都较好地反映了矿体的产状和规模。新的工业金矿体的发现，更加证实了壤中气汞测量找金矿脉的有效性。通过壤中气汞异常的评价，认为４号矿脉的北部，５号矿脉的南部，Ｈｇ２号异常的南部及Ｈｇ３号异常的深部有较好的开采远景，而４１号、１５号、２０号石英脉则无工业价值。The southern Lianhuashan gold field in Chifeng is covered by eolian loess. Many mercury gas anomalies in the site have been delineated by the method of mercurial gas survey in soil. The shape and scale of the deposit are circled by the mercury gas anomalies above. The productive gold veins of No.4 and No.5 wells reflected by the occurence and size of the anomalies confirm the availability of gas mercury survey in soil in addition to the discoveries of industrial ores. It is held by the evaluation of gas mercury anomalies that there are mining perspectives at the north of vein of No.4 and the south of vein of No.5 and the depth of vein of No.101. Whereas the veins of No.41, No.15 and No.20 are not industrially available.
