摘要 研究了赤峰地区金矿床中不同介质中的As、Sb、Mn和Zn特征,简要地讨论了各元素形成异常的机制,指出了该区金矿床中这4种元素的基岩地球
化学异常特点:As异常为宽而低缓,Sb异常为窄而高,Mn和Zn异常为环带状,这4种元素的垂向分带性不明显。本区金矿中的方铅矿中Sb含量特别高,
远高于其他硫化物中Sb含量。在本区残坡积物组成的土壤中As、Sb、Mn、Zn明显富集,显著高于基岩中相对应的含量,但是基岩、蚀变围岩及矿体上方
的残坡积物中这些元素含量趋于均匀化,大大地降低了这些元素对金矿的指示意义。

Abstract: This paper has studied As,Sb,Mn and Zn characteristics of different rocks and minerals as well as soils in gold deposits
of Chifeng area and briefly discussed the formation processes of their anomalies. It is shown that the primary anomalies of As are
low and wide,those of Sb are narrow and high,and those of Mn and Zn assume the zoned form. All these four elements do not show
obvious vertical zonation, and the Sb content is far richer in galena than in other sulfide minerals.It is also discovered that
these elements are richer in soils than in rocks, but they tend to be uniform in soils above the rock,altered rocks and ores, which
obviously decreases their indication significance for gold deposits in this area. |
