Many massive sulfide deposits that have been found abroad were formed by deposition of sulfides from hydrothermal system on the sea floor,and combined with sedimentation and alteration. Therefore,both primary halo in strata and secondary halo in altered rocks surroundtng the ore deposits are useful and should be studied. Mn halo ,anomaly of T1 ,Ba ,Hg ,As and Zn, enrichment of complex anions, distribution feature of minor mineralization elements,Co/Ni ratio of pyrite, lead isotope and ,especially,the adding of Mg and leaching of Na in massive sulfide Cu deposits ,are practical indicators for exploring massive sulfide deposits.

近年来国外发现了许多大型块状硫化物矿床,而我国进展还不大。原因之一是我们对这类矿床的地质特征、成矿条件尤其是找矿标志研究还不够。这是一类成矿物质通过热渡作用在海底沉积而成的特殊矿床,故在找矿勘探时既要研究沉积成矿时形成的原生晕,又要研究热液经过围岩时蚀变而产生的次生晕。Mn晕、Tl、Hg、Ba、Ag和Zn等元素的异常,络合剂元素的富集,微量元素的分布,铅同位素,岩石化学异常指数尤其是块状硫化物Cu矿中Mg的富集和Na的贫化,都是实用的地球化学找矿标志。

As an example of Shuijingtun gold deposit,fourteen gold close related indicator elements were selected to calculate the verti-cal zoning sequences of the elements and the spatial primary halo development feature. And the composite geochemical primaryhaol model Was established.

以冀西北水晶屯金矿为例,选择了与金矿化关系密切的14种指示元素,研究了该矿床的地球化学原生晕特征,并对局部地段含矿性作了初步评价。

This paper focuses on the geochemical characteristics of major ore-controlling structures, zoning sequence of indicator elements from the primary halo and denudation in the Hebaoshan Gold Ores. The Hebaoshan Gold Ores is situated at the intersection point of the Chongan-Shicheng Structural Belt and Jianning-Jianou Structural Belt in Fujian Province. Take the Hebaoshan ore block as an example, which is the major ore belt of the Hebaoshan Gold Ores. It is concluded that the difference of occurrence and denudation...

This paper focuses on the geochemical characteristics of major ore-controlling structures, zoning sequence of indicator elements from the primary halo and denudation in the Hebaoshan Gold Ores. The Hebaoshan Gold Ores is situated at the intersection point of the Chongan-Shicheng Structural Belt and Jianning-Jianou Structural Belt in Fujian Province. Take the Hebaoshan ore block as an example, which is the major ore belt of the Hebaoshan Gold Ores. It is concluded that the difference of occurrence and denudation between the southern and northern ore blocks in the No. 2 mineralizational belt of the Hebaoshan ore block results from the tensomshear fault of the EW trend.

本文以何宝山矿段为典型实例,较系统地论述了矿区主要控矿构造地球化学特征,探讨了矿区原生晕指示元素分带序列和金矿化剥蚀程度。认为矿区主矿带何宝山矿段Ⅱ号矿化带南北两段产状及剥蚀程度的差异,系受东百向张扭性断裂(F5)成矿后活动影响所致。
