摘要
本文通过对湖北潜山热水井中地震观察电缆表层水垢成分的分析，发现水垢中主要金属元素以硫化物或硫酸盐类矿物形式存在，并出现Ａｕ、Ａｓ、Ｓｂ、Ｚｎ等元素的浓集。Ａｕ在下部（还原环境）最富集，上部（氧化环境）也有浓集，但在中部（即氧化—还原界面附近）贫化；而Ａｓ、Ａｇ等则在中部浓集。
By means of the composition analysis of the scale on the surface layer of the seismological surveying cable in Qianshan geothermal well in Hubei,it is indicated that the metal elements in the scale take the form of sulphide or sulfate and the Au,As,Sb,Zn and some other elements in the scale are concentrated,of which Au mainly enriched at the lower part with a reductive environment and partly at the upper part with a oxditive environment.At the middle part near the boundary line between the reductive and oxidative environment,the Au,Ag and some other elements are enriched but Au is poor.Finally,the active faults and the possibility of the geothermal water metallogenesis in this area are discussed.
