江西省于都县营脑河子背区段汞蒸气测量应用效果

Application of Mercury Vapor Measurement in the Hezibei Section of Yingnao District, Yudu County, Jiangxi Province

摘要: 江西省于都县营脑河子背区段赋存有破碎带蚀变岩型银金铅锌矿体。由于其地表覆盖严重，原生矿体均隐伏较深，矿体产状及连接目前尚未完全搞清。该类型矿化与构造破碎带关系密切，所以通过汞蒸气测量确定区内主要断裂和破碎带构造的产状，以进一步验证本区钻探控制的深部北西向矿体、物探解译矿致北东向异常的有效性，从而确定本区段构造格局，查明赋矿构造产状及规模，为深部钻探施工提供可靠依据。

Abstract: Fracture zone altered rock type silver-gold-lead-zinc mineralization has been discovered in the Hezibei section, Yingnao District, Yudong County, Jiangxi Province. Due to serious surface coverage, primary ore bodies are buried in the deep so that the occurrence of ore bodies is not yet well understood. This type of mineralization is closely related to structural fracture zone; mercury vapor measurement is thus used to determine the main faults and fracture zones in the section. We further demonstrate the effectiveness of drill-controlled NW-trending ore body and geophysics- interpreted NE-trending anomaly. On the basis of this study, we can determine the structure framework, ore-controlling structure and the size of ore bodies, which can provide more information for future drilling.
